摘要
本文从空间受力出发,研究了顶梁、掩护梁、前连杆及后连杆在图1所示荷载情况下的受力和变形,解决了掩护梁的外力矩计算及扭矩的分布问题。最后,以JY_(320)掩护式液压支架掩护梁为例,做了数值计算,其结果与实验值对比符合较好。
In this artiele, from place forces system, studied forces relation and deformations relation of roof, shield canopy, and front and rear linkages which were acted by forces flgure 1 signaled; resolved outer moment calculation and internal moment distribution of shicld canopy. At last, calculated mumcrically JY_(320) shicld canopy of the Shiclded Powered Support, and compared the results of calculation with experimant. The comparision proved that the method of the essay is accurate.
