SIMULATION ON THE COMPUTER OF THE RUNNING OF A VEHICLE WITH TILTING BODY

The running of a vehicle with tilting body is simulated on the IBM 360/40 computer for the purpose of comparing different curve and body rotation detection systems (with or without feed back) relative to the limit conditions of the track. For the simulation, the following data are used: 1. Track: Curve radii - Superelevation--Irregularities measured every 5 metres according to the track condition record. 2. Vehicle: Running speed - Parameters relative to the rotation, such as the detection time and response time of the mechanism controlling the rotation. As result of the simulation, moment by moment, the characteristic trend of the uncompensated acceleration on the coach body is obtained for the whole of a speed-range according to different characteristic parameters of the system.
