发动机总成动力学参数的测量

The Survey of Engine Unit Dynamics Parameter

介绍了三线扭摆法是测量发动机总成动力学参数的常用方法,通过分析转动惯量的相关原理及公式得出,只要对简单参数的测量,就可用三线扭摆法计算出所需要的动力学参数,在发动机总成动力学参数测试试验中,该方法操作简单,精度非常高。

Three-string pendulum is to measure the dynamics parameter of the engine unit common method. In this paper, by analyzing the relevant theory of inertia and the formula derived, three-string pendulum as long as it can be a simple measurement of the parameters needed to calculate the dynamics parameters. Dynamics parameters of the engine unit tests, also can be seen three-string pendulum method is simple, highest aceuraey.
