Ride Dynamic Simulation of Armored Vehicles and Field Test Validation

摘要

This paper studies the problem of vehicle (wheeled vehicle, tracked vehicle) ride dynamics over rough ground or cross small obstacle. A unified vehicle ride dynamic model based on state equation is built up which includes random and fixed ground figure, three-dimensional bodywork, and etc; Tire and track affection are considered according to wheeled vehicle and tracked vehicle respectively; Special condition are considered such as impact between wheel and suspension gear, and corresponding module are bui Simulation outcome and field dates are compared to check and assess the model, and the human-vehicle-ground model proved to be acceptable. The model and its method can be used for armored vehicle design and vehicle dynamical analysis, and give technical support to digitized battlefield.
