曲轴疲劳试验中的载荷标定方法及其误差

Methods for Load Calibration and Load Error Analysis in Crankshaft Fatigue Testing

本文介绍了曲轴疲劳试验中常用的两种载荷标定方法即位移法和应变法。根据实测数据对它们所产生的误差进行了分析讨论。结果表明应变法的载荷精度远高于位移法。

This paper describes two load calibration methods generally used in crankshaft fatigue testing, i. e. displacement method and strain method. Analysis and discussion on their load accuracy were made based on experiment data. It was. found that strain method had a much higher accuracy than the other.
