摘　　要：传统的汽车惯性式制动试验系统采用机械惯量盘模拟汽车运动惯量,这种系统体积大、惯量调整困难、自动化程度不高,针对这些问题,提出了基于电惯量的汽车惯性式制动试验系统的设计思想。该设计通过对机械惯量数学模型的分析,提出了用控制算法控制电动机,使它的输出惯量能模拟机械式惯量盘的惯量,即用“电惯量”代替“机械惯量”。文中用MATLAB软件对系统性能进行了仿真研究并作了可行性的分析,研究结果表明设计是可行的。The traditional Automobile-inertia -brake-testing-system adopts the Mechanical Inertia pan to imitate automobile the Moving Inertia. This kind of system volume is bigger than new one, more difficult in inertia adjusting, and lower in automation degree. Aiming at the problems, this paper puts forward the innovative design of Automobile-inertia-brake-testing-system based on electrical inertia. The mathematic model of the Mechanical Inertia is analyzed. To use the algorithm to control motor, the authors make the output inertia generated by the controlled motor can imitate the Mechanical Inertia, then apply electrical inertia to replace Mechanical Inertia .The simulation result shows that the design idea is correct and feasible, stronger in system rubustness, lower in cost, more accurate in control quality, and higher in automation level.
