摘　　要：平衡千斤顶受冲击频繁,且所受静力很大,经常造成活塞杆从卡键槽处断裂,受专业知识及试验条件的限制,使用方和生产厂家很少对此进行全面专业的失效分析,从而影响设计结构的优化。本研究通过试验数据分析、受力软件模拟和静力的理论计算等方法,分别从疲劳和静力拉伸两方面对活塞杆的断裂原因进行了详细分析,最后给出了适合的结构设计建议,为后续平衡千斤顶卡键式活塞杆的设计提供了理论基础。The impact of the balance jack is frequent,and the static force is very large,often cause the piston rod from the keyway fracture,limited by professional knowledge and test conditions,users and manufacturers rarely carry out a comprehensive professional failure analysis,thus affecting the optimization of the design structure.In this researh,through the test data analysis,force software simulation and static theoretical calculation and other methods,respectively from the fatigue and static tensile two aspects of the fracture of the piston rod are analyzed in detail,finally gives the appropriate structural design suggestions,for the subsequent balance jack clamp key piston rod design provides a theoretical basis.
