摘要
针对传统底盘测功机惯量模拟装置存在振动噪声大、体积大、模拟精度不高及不能实现惯量无级调整等缺点,用加载电机代替原有的机械飞轮,分析了惯量电模拟的理论基础,推导出惯量电模拟时加载电机所需的动态补偿转矩。分析了惯量电模拟的实现方法,并在DCG-10E型底盘测功机上进行了汽车的加速性能试验和滑行试验。试验结果表明:在采用惯量电模拟时,底盘测功机的测试精度提高了4.4%,说明惯量电模拟方法是可行的。
In order to solve the problem that the inertia mechanical flywheel analog system had large vibration noise,big volume,low analog precision and without inertia stepless adjustment,the original mechanical flywheel was replaced by a loading motor. The theory of inertia electric analog were analyzed,and the dynamic compensation torque of the motor was deduced during inertia electric analog. The implementation method of inertia electric analog was analyzed,and the acceleration test and coast-down test of the vehicle were researched on the DCG-10E chassis dynamometer. The experimental results show that the accuracy of the chassis dynamometer is improved by 4. 4% when the inertia electric analog is used. So the the inertia electric analog method is feasibility.
