摘要
本文通过对液压支架上两个结构尺寸,即掩护梁上铰点至顶梁顶面之距和后连杆下铰点至底座底面之距的变化,对支架进行受力分析,找出它们对受力影响的变化规律.
The regularity of changes in the forced influence through the two construction-sizes in the power supports-the changes of distances between the up-hinge on gob shield to head face of head shield and down-hinge of back connecting rod to the face of pdeestal is obtained through the analysis of the force of power supports.
