摘要
在履带车辆动力传动系统设计及匹配研究中,系统的建模是一个非常复杂的过程,耗时较长,给研究工作带来诸多不便,利用专业软件进行建模与仿真可大大提高研究效率.以某履带车辆为研究对象,采用AVL公司的Cru ise软件,建立了整车直驶模型,讨论了后传动比以及发动机外特性曲线形状的变化对车辆动力性的影响,对车辆动力传动一体化结构设计及性能匹配的研究提供参考.
Power train modeling brings a great deal of inconvenience to the research of tracked vehicles for its complication and long period. Modeling and simulating with professional software can increase effi- ciency obviously. This paper adopts Cruise developed by AVL, takes a certain tracked vehicle as the re- search target to establish straight run model, and discusses the influences of rear drive ratio and the shape of engine＇ s external characteristic curve on the performances of the entire vehicle. The study provides references for the designing of unified powertrain structure and performance match of powertrain system.
