| In this dissertation, according to the theory of Mechanical Dynamics and Multi-body Dynamics, a simulation model of NJ2046 light off-road vehicle including suspension system, steering system and tires is built with the software CarSim and so the vehicle steering characteristics are analyzed with the step angle input of steering wheel. It is found that the steering characteristics are different when the velocity and load are different, and the relationship between steering characteristics and velocity and load is presented. At the same time, with another software which can calculate and analyze the brake system, the braking process is analyzed in different velocity and load. The road tests of this vehicle's braking and handling performance have been processed; it is found the simulation analysis is coherent with the testing data, and the braking and handling performance of this vehicle are well. |
