本文假设当液压支柱受到偏载荷时,由于密封件的弹性变形,刚体与活柱轴线间将产生相对转角与套接处的弯矩成正比,导出了弯矩应力的计算公式,并将计算结果与用其它方法计算的结果进行了比较。
This paper assumes that when the hydraulic prop receives partial load, the formula of moment stress is deduced due to the elastic deformation of the seal and the relative rotation angle between the rigid body and the live column axis. Compared with the results calculated by other methods.
