液压架架设计中目前普遍应用四连杆机构。四连杆机构设计的好坏直接影响液压支架某些重要参数的确定。它也直接影响液压支架性能、强度及受力状况的改善。为了进一步推动液压支架优化设计,开拓设计新方法,1987年12月5日～7日由郑州煤矿机械厂提议,在郑州组织召开了液压支架四连杆优化设计研讨会。参加会议的有煤炭部技术发展司、制造局、部属高等院校、科研院及液压支架制造厂等共13个单位代表32人。
Hydraulic rack design is currently widely used four-bar linkage. The design of the four-bar linkage directly affects the determination of some important parameters of the hydraulic support. It also directly affects the hydraulic support performance, strength and stress conditions improve. In order to further promote the optimal design of hydraulic support and develop new design methods, proposed by Zhengzhou Coal Mining Machinery Factory from December 5 to December 7, 1987, a symposium on optimization design of hydraulic support four-bar linkage was held in Zhengzhou. Attended the meeting were the Ministry of Coal Technology Development Division, manufacturing bureau, subordinate colleges and universities, research institutes and hydraulic support factory a total of 13 units representing 32 people.
