摘要
本文叙述了50t平板车中桥桥壳弯曲载荷、半轴扭矩工作载荷谱测定方法及其试验程序载荷谱的编制方法。运用“浮动零线法”解决了测试时载荷的“直流分量”和“交流分量”的比例问题。并对8级程序载荷谱中如何计算每级的循环次数提出了近似的计算方法。
The paper describes a method of measuring the field loading spectra for the differential axle housing and wheel shaft of a 50t flat truck and determining corresponding testing program loading spectra. A technique called 'loating zero line method' is introduced to assure proper ratio between DC component and AC component of the load. Then an approximarion of calculating the cycle numder for each grade in an eight grade loading spectra is also proposed.
