Control failure


I'v come across the strange phenomena in the train, Super Kuroshio 28 to Kyoto, while the straight running over 80 km/h, only the 4th train left roles about 2 degree, so the door edge line is not parallel to frontal nor posterior train, very incredibly strange phenomena happened. This tendency disappears below the speed of 60 km/h so the door sashes duplicated into parallel.
This shot from a frontal seat of No 4th train shows only the 4th cage plays strange the left side roling conditioned while straight running the degree of inclination was about 2.
The professional in this field would easily recognize that while the straight running this strange photo must not be taken if the pendulum control system was working well as designed.
Considering about the special adjusting construction, computer controled automatic pendulum adjusting mechanisms, probablly the gyro or it's controller must have lost a good control.
I told about the failure to the professional person at Shin Osaka St. of course the number of the train also, モハ380-26.

Beer caps putting on the small shelf falls down provided a small window sash inward relatively easily if get into the curve at high speed with ready angle minus 2 degree(left side role).
Sitting on the window side and the second row right truism beer strewn on the floor more dirty clothes right of retention or customer reached through the left window side passed through my feet on second row left aisle despite the state after passing through the curve and while straight running.

The corrections by the pendulum system is activated in order to compensate the centrifugal effect while curvature running at relatively high speed, then such kind of correction must not be done except in those situations, so designed and electric and mechanical systems are firmly adjusted and set according to the principles?
