摘　　要：目前使用的5×135气动马达存在严重的动不平衡问题,工作过程中振动和噪音比较大,降低了马达的工作效率和使用寿命。针对现有气动马达存在的问题,通过UG等三维建模软件对其进行三维建模来得到特征参数,再由所得参数进行动平衡计算。根据计算分析后的结果对曲轴进行改进,将改进后的曲轴用同样方法进行计算,把计算结果与未改进时进行对比,做到保证马达的动平衡又不增加马达质量,并通过有限元分析软件ansysworkbench14.5对现有曲轴和改进后的曲轴进行静力学分析,将改进前后的分析结果进行对比,使改进后的曲轴应力分布更为合理。There are serious dynamic unbalance problem of the air motor presently,the vibration and noise are too much,These decrease the work efficiency and service life of the air motor. About the air motor problem, to get the charac- teristic parameters by the UG or other 3d modeling softwares to make the three-dimensional modeling, then make the dynamic balance calculation according to the parameters.Make improvement to the crankshaft according the analyzed result,then do calculation to the improved crankshaft using same method, make the comparation of the calculation result with before, to reach the aim of making the motor moving stably but without increasing the motor＇ s weight.Make the static analysis to the present and improved crankshaft bythefinite element analysis software of ansys workbench14.5,compare the analyzed result and ensure the crankshaft stress distribution more reasonal after improvement.
