| 摘要： | Automobile chassis dynamics performance is vulnerable to numerous kinds of uncertainties to cause the movement devia-tion between an actual and an ideal movement trajectory.In order to improve the robustness of vehicle dynamics performance,a new model for vehicle steering-suspension is proposed.In the model,a mine truck chassis with steering system,braking system and suspen-sion system is built using ADAMS,and some simulation data is integrated in the system to complete robustness for the vehicle dynamics performance.The controllable variables include the structure parameters of steering mechanism and alignment parameters of suspension,and environment noises include load,driving force and steering torque.Optimization objective is composed of the maximum turning angle error for steering mechanism,the maximum braking sideslip and the maximum swinging angle for front wheel on bumpy road.Through the approximation method,the response surface models for optimization objectives have been built.Lastly a comparison for the optimiza-tion results based on the robust model and a traditional optimization model has been carried out.The results show that the standard devia-tions of optimum objective in the robust model are decreased at the same noise factors of load,driving force,steering torque and the ro-bustness of dynamics performance for the mining truck is improved. |
