摘　　要：在设计曲轴连杆式低速大扭矩液压马达的连杆结构时,不能忽略连杆滑靴底面变形的影响。采用ANSYS软件对连杆进行了有限元分析,表明由于排量、压力等诸多因素的影响,曲轴连杆式低速大扭矩液压马达的连杆滑靴底面会出现较大的变形。变形差量可由密封带巴氏合金的正常磨损得到补偿,以保证静压支承润滑油膜的形成。The deform of slipper pair bottom surface should not be neglected while designing the connecting rod structure in camshaft connecting rod type of low speed high torque hydraulic motors. The finite element analysis was performed on connecting rod with the help of ANSYS, and the problems that should be noticed while manufacturing were pointed out. The influence of rotating angle on stress, total strain and shape deform of the connecting rod structure can be neglected. The cross section shape and depth of oil cavity on slipper pad must be fulfilled to guarantee the function of hydrostatic bearing slipper pairs.
