履带车辆双侧变速箱传动系统建模及动态仿真

随着现代履带车辆动力传动系统越来越趋向于一体化、综合化和集成化,传统的分析工具和手段已经不能满足现代机、电、液和自动操纵控制系统的需要.利用专业化的模块化模型进行车辆性能分析是分析工具发展的必然趋势.本文应用模块化建模手段,建立了双侧变速箱车辆动力传动系统及整车的仿真模型,对车辆的加速性进行了仿真研究并与实车试验结果进行了比较,验证了所建模型是正确和有效的,能够反映出系统的动态特性.该模型和建模方法能够方便地对车辆的性能进行预测并为改进设计提供依据.

MODELING AND DYNAMIC SIMULATION OF DOUBLE SIDE GEARBOX TRANSMISSION SYSTEM FOR TRACKED VEHICLES

With the trends in the development of tracked vehicle driveline, fowards merging, synthetization, and integration of individual members, the conventional tools and means of analysis can no longer satisfy the demands of development in modern mechanical, electricical and hydraulic systems and automatic steering control systems. It is an inevitable trend to analyse vehicle performance based on modular models. Based upon modular modeling, a model for the driveline of tracked vehicle is developed.The acceleration performance of the vehicle is simulated and studied. Results of simulation accord well with the results of experiment.The model and its method of analysis can be used conveniently to predict vehicular performance.
