摘　　要：为保证350 t钳夹车压柱油缸及其相关部件的运行稳定性,采用了理论分析计算与动力学系统数值仿真相结合的方法,对钳夹车压柱油缸及其相关部件的稳定性进行了研究.基于各构件稳定的几何条件及系统的受力状态要求,得出了各相关构件轴线间的许用夹角值,并讨论了钳形梁联接车耳、安全销对横向稳定性的影响.研究结果已被采纳,结果令人满意.For operation stabilization, the stability of 350 t schnable car hydraulic cylinder and interrelated parts was studied by theoretical analysis and numerical simulation in the dynamic system. Based on the geometry conditions with all components steady and the system force state, the allowed angle is obtained between the axesis of the interrelated parts, and the influences of hinge bushes and safety-pins are discussed. The expefimet result has been put into practice, and the performance is satisfactory.
