摘　　要：为了提高内锁紧油缸10000次循环加载试验效率,通过重新设计试验液压回路,利用单片机控制油缸进行往复循环试验,实现了油缸运动过程中的动作自动转化以及自动计数等功能。试验和应用证明,该试验方案自动化程度高,不仅提高了产品的试验效率,也降低了产品损坏的风险,具有一定的推广价值。In order to improve the efficiency of the inner-lock cylinder＇s ten thousand times cyclic loading test, through redesigning the hydraulic circuit of experiment and using single-chip microcomputer control oil cylinder reciprocating cycle test, the automatic transformation in the process of the oil cylinder＇s movement and the automatic counting function are realized. The test and application show that the test scheme＇s degree of automation is high. The scheme not only improves the test efficiency of the product, but also reduces the risk of product damage, which has a certain popularization value.
