摘要
负荷拖车是用来测试车辆动态牵引性能的现代车辆测试设备,测功系统在试验过程中为之提供可调节负载,对拖车性能起着决定性的作用。文章在简述负荷拖车结构及工作原理的基础上,介绍了拖车的新型测功系统——液粘测功机的结构、工作原理及特性,并分析了测功系统的恒转矩控制、输出稳定转矩的响应情况,及其对改善负荷拖车试验性能的贡献。
Mobile Dynamometer is a modern equipment for measuring dynamic traction performance of vehicles. Power-measuring system, playing a decisive role in improving Mobile Dynamometer's performance, provides adjustable load for it. On the basis of simply describing the structure and working principle of Mobile Dynamometer, this article introduces the structure, working principle and traits of the new power-measuring system-hydroviscous dynamometer, and gives an analysis of constant torque control principle of power-measuring system, course of steady torque output, and their contribution to improve Mobile Dynamometer's testing performance.
