摘要
针对重叠式短推杆在使用过程中易出现弯曲变形的现象进行了分析,计算结果表明设计强度不够是造成推杆弯曲变形的主要原因。在此基础上,提出了具体的改进方法与措施。
The deformation of a certain relay bar is analyzed in the paper. The calculation result indicates that the main reason of the deformation of relay bar is that yield strength of material is less than calculation strength. Based on this, an improvement method is put forward.
