Zero Thrust adjustment:Almost hopeless!

I've talked about the negative effects of thrust angles in passenger cars and the need to eliminate them, but today he talks about the possibilities.

If you operate the steering even a little while going straight, the car will change the direction of driving. The driver should know the direction change very sensitively. Then, is it the same with a forklift with rear wheel steering? The same thing will happen physically.

Let's assume a state where both front wheel steering and rear wheel steering functions are provided. When the rear wheels are fixed at the center position that matches the traveling direction, the front wheels can also be kept straight at the steering center position.

If you steer the rear wheel slightly to either side and shift it from the center, the car will start turning, and if he tries to keep going straight in this state, the front wheel must be in phase and steered at the same angle as the rear wheel.

The direction of the left-right vector sum of the rear wheels and the deviation angle from the center of the car may be called as the thrust angle, or the vector sum corrected by the front wheels.

If you write so far, it is easy to think that you should correct the deviation angle on the rear wheel, but in reality it is not easy because there are many uncertainties.

When the arc drawn by the thrust angle and the radius of the curve match when turning, a dead zone occurs in the steering pressure. At this time, the car turns along the curve even if you take your hand off the steering wheel.

Since the load moves back and forth when starting and stopping, he changes the amount of correction for thrust.

When the forward weighted movement is stopped, it will be over if it starts at the steering position as it is, and it will be undercut and it will be necessary to increase the number of turns. The steering action is complicated due to the action, and it feels uncomfortable. Even if the car is equipped with EPS, the basic geometric and physical deviation cannot be corrected.

It is an unreasonable consultation as if he is trying to correct the roll movement habit that should be corrected by the aileron tab on the airplane from the yaw movement by force on the rudder tab. Unpredictable bad habit appears when the driving situation changes.

Thrust Angle adjustment for Zero degree

Yesterday, I mentioned about the thrust angle of automobiles and its influence, and the necessity of installing a thrust angle adjustment trim mechanism.

Today I want to tell the practice and results of error adjustment in the absence of a trim mechanism about almost every car.

It must be possible to adjust the thrust angle to zero while driving, depending on the keen human senses relatively easily.

As an usual manner, if this is not possible, we must establish it by repeating cut and error, considering all the uncertainties unrealistically.

This thrust adjusting procedure requires a relentless determination and tenacity to accomplish it at any rate, mentally and physically, while repeating extremely troublesome adjustments, efforts to bring the infinitely misaligned thrust angle closer to zero continue endlessly.

"But when the ideal zero-thrust condition is achieved, he will immediately be impressed by the joyous and wonderful handling that the driver has never experienced before.

Once he tastes this feeling, he doesn't want to drive a car that has a misaligned thrust." 

In other words, when he establishes zero thrust for a car that he wants to let go, he always changes his mind and decides. It's supposed to change, because he's got rid of everything that had the potential to feel uncomfortable.

A car that flows to the right, a car that does to the left, a car that has to change direction immediately when it receives some external disturbance, and a car that has to be corrected in a hurry.

However, from a geometrical point of view, there is no peculiar habit regarding the direction during exercise. It can be changed in any way depending on the adequate adjustment. 

The steering sensation of the vehicle which is easily disturbed by some external stimulation, is fixed and stable at an adequate position around the center with comfortability under appropriate resistance.

Thrust angle?

Recently, I felt uncomfortable with the steering of the Audi A-3 DBA-8PCAX, so I measured the thrust angle with a laser pointer device. As a result, the angle value was a plus of 0.6 minutes. Because it is a sufficiently acceptable value of 3 digits or less, if the thrust angle is 10 minutes that is torrelance of European Automobile Safety Standard, if you go straight for 100 m, you will draw an arc to either the left or right for about 3 m. This deviation is unknowingly corrected by the driver. Then, if you continue to drive the car while correcting such a deviation, how about 0.6 minutes? Since the deviation is positive under the same conditions, it will occur 23 cm to the left and you will go straight while correcting this. As the thrust angle increases, the amount of correction increases. The driver has to concentrate on checking and correcting the state of deviation, which is very tiring. The amount of correction of the rudder when receiving a external disturbance varies, so it is unpredictable and driving, I feel sick in such a driving condition.

The recent car is equipped with EPS, and by memorizing the steering position when going straight, it is possible to take the thrust angle to zero in a Pseudo manner, but since it is always running while correcting the thrust, it is not possible to predict disturbance. The countersteering cannot be solved, and the difference between the left and right steering sensations remains the same, so the contribution of the EPS-Cal is only Pseudo.

From the idea of trimming adjustment for neutral position, vehicles need a geometric and physical establishment of axle and wheel alignment.

In the case of an aircraft, the position of the center of gravity changes depending on the condition of the load and burdened fuel, so the pilot always makes trim adjustments to maintain level flight, no matter how it is Autopilot or Human one.

From this point of view, I think that it is necessary to adjust the thrust trim in the direction of travel for automobiles as well, but although some concepts of 4WS have been mentioned, there is no report that delves into this point. 

In the case of automobiles, four wheels, it is unlikely that everything is exactly aligned with the all-wheel steering, but the front vector direction is always present independently, and therefore the rear is always present alone. Therefore, match these vector directions, that is, make the thrust zero discrepancy respectively. Should be possible as a matter of fact.

It should be aware of any driver as he gets a bit sticky and stable steering position near the center when the zero thrust discrepancy is established.  Almost no one has never experienced this feeling that is difficult to verbalize.

If you want safety and comfort in a vehicle, it's the first to introduce a "Thrust trim mechanism", not an electric motor.

This fact and truth should be known to every car maker.

I'm about to mention on the ultimate difficulty to establish the condition of "Zero Thrust Discrepancy" for ordinary vehicle.

Confusion

In Japan, which is in control of all military, economic and politics, and continues to be ruled by the specific foreign countries, no matter how much the truth is stated and the right direction are shown, nothing will change. It is the same regardless of whether the ruling party or the opposition party might change.

Even if you are connected on the website, information those are inconvenient for the Japanese Government will be erased immediately, so the public opinion will not change.

Some lawmakers argue in tune with those who say the truth, but he just seems to be trying to sell and stand out.

The person's physiognomy does not show "the Pain of Birth in pursuit of the Truth". 

He is merely making a play-stained angry expression in the eyes of the Ukrainian representative who has no enthusiasm to really appeal the truth.

This comedian is on the wrong stage.

Change our mindset!

Looking at the general public, there is a tendency to look ahead, to proactively play with measures, and to take a better benefit only by oneself. Dominate and exploit people If another one doesn't hear what is said, threaten and destroy to fatal.

The composition of the idea is really simple and it seems that even a child can think about it resulting to a same inferior conclusion.

We had been doing exactly the same thing all the time since recorded history with changing places and people. No regret nor repentance! 

Throw away all the temporally escape and lowly thoughts now!

It's almost time for us to realize this and abandon our self-centered thoughts so that we can all live in Peace, Happiness and Cheerfulness.

Even if the words, skin color, and eye color are different, all the people are the same, because we observe very beautiful alignment of the tissue cell construction with blood circulation in subcutaneous tissue those are exactly the same phenomenon.

We think we can do it in the modern society that is always connected worldwide on the Web, but can't we?

Abandon the killing weapons especially explosives of guns and remodel all tanks with caterpillars into the constructive heavy equipment to help with reconstruction and development for our future?

All the conflicts in the world are primitive and boring at all, so why not stop?

Kyoto Botanical Garden at Kitayama

All plants are very well maintained by excellent professional vendors and will not be disappointed whenever you visit throughout the four seasons. The same is true for the western flowers in the greenhouse. 12000 species of plants are nourished in a large area of 60 acres. You can enjoy hydrangea flower iris camellia, etc. It is directly connected to the subway Kitayama station, and the elevator is also available, so the transportation is ultimately convenient. Wheelchair users acceptable, also modern toilet is prepared.

How will be our countermeasure?

Is it correct that the fact that Japan was attacked by Nuclear weapons is the good reason why Japan does not have Nuclear weapons?

Is it correct to appeal to the world for the abolition of Nuclear weapons because of its misery?

On the contrary, is it helping to secure the absolute status of Nuclear-weapon states by giving fear to non-Nuclear-weapon states?

Japan's Nuclear development capability could be completed in a very short period of time if we want to.

Being able to put it in Orbit means that it can be dropped anywhere, but what about Japan's Rocket and Missile technology?

From the perspective of military power balance, is Japan at the forefront and always at risk of the outbreak of war?

Isn't it wondering from all over the world that Japan, which should be naturally armed with Nuclear weapons, does not do so?

If the United States permits Nuclear weapons, Japan should respond immediately?

That might be the case if Mr. Trump is re-elected, but what will we do?

Regardless of land, sea and air, it is an era of military equipment with unmanned equipment, but it seems that we are doing our best in the progress of Japan.

Japan's missile interception system seems to be advancing, but it may be okay to spend a little more budget.

It seems that the time of peace in the United States, "the Master Hinomaru", has already passed. The times have already changed significantly.

I think it is not the way Japan should be to live smaller while looking at the complexion around us, influenced by the situation in foreign countries.

It's almost time for Japan to awaken from 80 years of hibernation and live seriously.
