A Certain Type Of Front And Rear Turn To The Special Vehicle Handling And Stability

This dissertation based on ADAMS software research the maneuverability and stability of the vehicle united a research and develop project of a Multi-Axle special-vehicle with Four-wheel Steering.This dissertation has introduced the development course and control strategies and trends of the 4WS system and Multi-Axle Steering; built the special-vehicle dynamics model having twenty one freedoms which including body, tires, the 4WS system, suspend and so on by ADAMS software and disserted the theory and method and steps fully; and next, the dissertation has done a lot of dynamics simulating experiments adequately utilizing the trait of ADAMS to research the maneuverability and stability of the vehicle; and more, this dissertation has done many experiment of the real car to check the model and research the maneuverability and stability advanced; at last, this dissertation has studied and analysis the effect of main framework on maneuverability and stability by defining variables, and finally this dissertation gives some scheme and advice to improve the maneuverability and stability of the vehicle and the similar vehicle.
