Recorded Simulation Control Scheme. User's Manual. Volume II.

摘要

Recorded simulation control scheme is a method of generating realistic inputs for vehicle shake tests. The scheme involves generating axle displacement records by simulating vehicle operation over the specified terrain, storing the records in memory of a control system and using them to provide input signals to the vehicle shaker. This user's manual provides instructions on implementing the scheme in terms of two steps. Step 1: A complete program which can simulate motion of a three axle military truck using any of the previous developed four tire models is described. The tire models are: point contact model, rigid tread band model, fixed footprint model and adaptive footprint model. Instructions on using the program to create axle displacement records are given along with an illustrative example. Step 2: A control system which employs a digital processor, disc memory and input-output peripherals to generate shaker input signals from the displacement records is described. Instructions on operating the control system are provided through typical examples. (Author)
