Tracked Air Cushion Research Vehicle -Dynamics Simulation Program User's Manual.

摘要

A digital computer program was generated for use on the IBM 370/165to evaluate the dynamic characteristics of the tracked air cushion research vehicle. The manual provides a summary review of the analytical basis,the construction of the computer program and the necessary instructions for the use of the program. The analytical model is formulated with the primary objective of obtaining vehicle ride qualities. The major vehicle components (body,chassis,guidance cushions and levitation cushions) supported by the vehicle suspension system are represented in a dynamic mathematical model with a maximum of twenty degrees of freedom. The non-linear response of this model to rigid and flexible guideway excitations,turn and superelevation excitations,and aerodynamic forces are obtained using numerical integration.
