摘要
为精确地模拟实际工况中汽车传动系转动惯量,实现对多种汽车传动系冲击耐久性能的检测,基于机电混合惯量模拟方式设计传动系冲击耐久性试验台惯量模拟系统。根据机电混合模拟惯量原理,确定了飞轮组设计原则,建立了动能补偿系统。采用转速控制法实时控制电机输出转矩以补偿飞轮动能,调节系统输出惯量,并对试验台惯量模拟范围进行分析。结果表明,以基础惯量为10的试验台为例,按0.6g减速度设计时,通过调节飞轮组,结合电机控制,可模拟的汽车转动惯量范围为0~195,满足轻型、中型、重型车的惯量要求,且模拟精度高、试验成本低,有较好的工程实用价值。
For accurately and efficiently simulating the rotary inertia of automotive transmission in actual working condition, realizing the detection for durability of various automotive transmission, the inertia simulation system of endurance test--bed for transmission is designed based inertia simula- tion method, which has mixed the machinery and electricity. According to the hybrid inertia simula- tion method, the design principle of the flywheel groups is determined, and kinetic energy compensa- tion system is established. The electrical machinery is regulated by the rotational speed control method so that the kinetic energy for the flywheels is compensated and the efferent inertia of system is regula- ted, the simulation context of the test--bed is analyzed. Finally, taking the test--bed with the basal inertia of 10 kg m2 as example, when its designed deceleration is 0. 6g, the simulated inertia scope of 0-195 kg · m2 is realized by regulating flywheel groups and the domination of electrical machinery, the inertia requirements of light--duty vehicle, mid--size vehicle, and heavy--duty vehicle is met, and its possesses high analog accuracy and low experimentation cost, so that will be more useful in ac- tual application.
