Research On Driving Dynamics Of A Special Off - Road Vehicle

Multi-axis special vehicle is always used as the transportation and launch chassis of weapon system. Its’characteristics affect the performance of transportation and even the projection of weapon system directly. So it’s necessary to study the performance of the vehicle. It’s different from the common off-road vehicle in size、carried mass and working conditions.This paper studies the three-axis special vehicle. It uses relevant software to establish the correct model of the vehicle and simulation analysis. Finally, it comes down to the performance of the vehicle.This paper firstly analyzes the suspension. That is to say, first of all, it analyzes the characteristic of the suspension. Then it builds the model of the suspension by AD AMS/Car. And finally it estimates the simulation result according to relevant criterion and requirements.Then it analyzes and uses AD AMS/Car to build the whole system of the vehicle, such as steering system, chassis and powertrain. Finally, it carries on the performance of handling, riding and ABS and finally analysis of the vehicle according to the criterion. Thus it can come down to the paper of the driving performance of the vehicle.
