轮胎滚动阻力试验系统研究

许多汽车性能试验均在底盘测功机上进行，而轮胎滚动阻力是影确测试精度的重要原因。由于目前我国大多数企业均使用双滚筒式底盘测功机，所以设计双滚筒式测功机上轮胎滚动阻力测试系统，将为台试轮胎滚动阻力特性研究奠定基础。双滚筒式试验台上测试轮胎滚动阻力采用反拖法实现，滚动阻力测试系统由双滚筒式底盘测功机改制而成。通过对加载方式、误差处理方法、系统测试精度等问题的探讨，验证了系统的可靠性和准确性。

Study on Tyre Rolling Resistance Test System

Many automotive performance tests are conducted on chassis dynamometer,while tyre rolling resistance is an important factor to affect measuring accuracy.Because most enterprises in our country have been using the double drum type chassis dynamometer,designing tyre rolling resistance measuring system in double drum type dynamometer will lay a foundation for a table type tyre rolling resistance characteristic research.Measuring tyre rolling resistance on a double drum type test bench can be realized by using a reverse drawing method,the measuring system of rolling resistance is reformed by a double drum type chassis dynamometer.With discussion of loading type,error handling method,system measuring accuracy and etc.,the reliability and accuracy of the system are verified and approved.
