汽车传动轴似静扭试验台

Development of Vehicle Drive Shaft Quasi-Static Torque Testing Bed

本文主要论述了采用PC工控机作为控制核心,并配置了一个支持网络协议的通讯软件,实现在本试验台上对汽车等速万向节传动轴,进行5000Nm以下传动轴的似静扭和静扭断裂强度试验的工作原理和测试方法。

The paper reports the working principle and testing method about measuring fracture intensity of quasi-static torque and static torque for an automobile transmission shaft which is connected with a constant velocity universal joint rotating below 5000 Nm torque. The testing system abopts an industrial PC by means of a communication software for a metwork protocol. At the same time the paper elaborates the driving of main shaft, control of load and determination of measurement in detail. It also analyses the loading error and the measuring error so as to overcome and compensate it.
