Study on Modeling and Turning Performances for Electric Drive Tracked Vehicle Propulsion System

为准确分析某电传动履带车辆转向特性,运用现代设计理论与方法—协同仿真与虚拟样机技术,借助动力学分析软件RecurDyn/Track-HM和控制系统分析软件Matlab/Simulink仿真平台,建立了整车行动部分三维多体动力学模型和控制系统模型。以不同车速v、不同转向半径R下的转向特性为例,对其进行了理论分析与协同仿真分析,并通过与理论计算和试验结果对比验证了模型的正确性。该方法对深入了解整车的转向特性以及试验调试策略具有重要指导意义,可进一步缩短研制周期,降低研究成本,同时为履带车辆电驱动系统动态特性的深入研究提供了一条新的思路。

In order to analyze the turning performances of an electric drive tracked vehicle exactly, with modern design theory and methodology-collaborative simulation ＆ virtual prototyping was applied, the 3-D multi-body dynamics model of the whole vehicle walking parts and control system model were built based on the simulation platforms on dynamics analysis software known as RecurDyn/Track-HM and control system analysis software known as Matlab/Simulink. Theory analysis and collaborative simulation on turning performances in different velocity υ and turning radius R were made. The correctness of the model was validated by comparing with theory computer and test result. The method has instructional signification on comprehension of turning performances and test debug strategies, and the method can short the circle of the research and cut down the costs, and also form a new idea on profoundly research of dynamic characteristics for electric propulsion system of the tracked vehicle.
