美国西南研究所研制成一种微机控制系统,用以控制两种以柴油机为动力、双路液压变速驱动的试验型军用履带车辆。本文通过实车试验数据和计算机模拟,说明驱动系部件的稳态特性和动态特性。文中介绍了传动装置开环控制的野外试验情况、西南研究所开发的闭环控制方程的内部研究方案、以及闭环控制下车辆动态响应的模拟。
Southwest Institute of the United States developed a computer control system to control two kinds of diesel powered, dual hydraulic variable speed test military tracked vehicles. In this paper, the steady-state characteristics and dynamic characteristics of driving system components are demonstrated through real vehicle test data and computer simulation. This paper introduces the field test of open-loop control of transmission, the internal research program of closed-loop control equations developed by Southwest Research Institute, and the simulation of vehicle dynamic response under closed-loop control.
