摘　　要：液压千斤顶在工作过程中常常会出现弯曲现象,以等截面法、不等截面法对液压千斤顶进行压杆稳定性理论计算,同时应用ANSYS分析,对等截面法和不等截面法理论计算进行验算,从而进一步核对理论计算结果,通过比较计算结果来完善千斤顶设计中的压杆稳定性计算方法,找出影响压杆稳定性的关键因素。The hydraulic cylinder will present the curving phenomenon frequently in the work process, by the constant section method, the ranging section method,carry on the strut bracing stability theory computation to the hydraulic cylinder, simultaneously using the ANSYS analytic method, the coordinated method of sections and the constant section method will not carry on the checking calculation, thus further school team theoretical calculation result, will consummate in the cylinder design through the comparison computed result the strut bracing stable method, will discover the influence strut bracing stable key aspect.

关 键 词：油缸 等截面法 不等截面法 压杆稳定性
