| 摘 要： | 在液压支架设计中，顶梁偏载、掩护梁受扭转时，需要对掩护梁和前、后连杆进行扭转强度计算。作者把掩护梁和前、后连杆一起考虑，引出掩护梁和前、后连杆组成的虚拟系统。根据求解静不定问题的一般方法，利用卡氏定理建立变形协调关系，求得了前、后连杆力矩分配的一般公式。

| Abstract: | in design of shield support,it is necessary to calculate torsional strength of the debris shield, the front and rear linkage when The canopy has offset loading,and when the debris shield is in torsion.The author derives a virtual system of debris shield and the front and rear linkage.Based on the normal method for solving static indetermination problem,the author established a general formula for solving distribution of moment between the front and rear linkage by using Castigliano theory to coordinate deformation. |

| Keywords: | powered support torional strength distribution of moment |
