摘　　要：　为提高复杂机电系统的建模效率,基于面向对象的物理系统建模语言Modelica,建立了液力机械传动箱基本组件的可重用参数化模型.所建模型具有无因果性,支持类结构(面向对象,多重继承,模板),可重用等特点.利用面向对象的基本构件模型,建立了某履带车辆液力机械综合传动箱模型,并进行了动力传动系统的换挡动态特性仿真.虽然没有对结果进行试验验证,但从定性分析看,所建模型能正确地反映换挡动态特性,可用于换挡动态特性评估以及传动箱动态载荷的计算.In order to increase modeling efficient, the reusable subsystem models of hydraulic transmission , based on object-oriented physical modeling language Modelica, was developed. The characteristics of the models that distinguish the traditional simulating models are of non-causal, supporting class structure (object-oriented, multi-inheritance, and template), and reuseable. Modeling and simulating of the integrated hydraulic transmission of a tracked vehicle was carried out based on Modelica/Dymola software. The results show the expected behaviors, however since no measurements has been available it is hard to say how near the truth the model is, just that the qualitative behavior is correct.
