大型汽车底盘动态模拟测功机测控系统

大型汽车底盘测功机的关键部分是行车阻力的精确模拟与控制。本文论述了大型汽车底盘测功机动态电模拟行车阻力系统的加载原理，组成与控制过程，通过实验证明其控制效果极佳，汽车加速过程与路面实际加速曲线贴合度误差不大于３％。

Control System in Large Chassis Dynamometer

Accurately simulating and controlling driving resistance of a motor vehicle is the key part of large chassis dynamometer, the paper elaborates the loading principle, constitution and control process of the driving resistance simulation system in dynamometer. The difference between acceleration curve in simulation and that in experiment is less than 3%.
