摘　　要：针对某中吨位挖掘机回转马达在作业时产生较大噪声的问题,以斜盘式轴向柱塞回转马达为研究对象,采用流场仿真方法对轴向柱塞马达进行动态模拟,探究柱塞马达配流盘上不同阻尼槽的结构和参数对柱塞腔的压力脉动和出口流量脉动的影响关系;结合多目标麻雀搜索算法对阻尼槽参数进行寻优,得到最优的阻尼槽参数组合。结果表明:在一定范围内增大阻尼槽的深度和宽度参数都能在一定程度上抑制柱塞马达的压力和流量脉动,U形阻尼槽优于三角型阻尼槽;对U形槽结构参数进行优化后,马达柱塞腔的压力脉动幅值、马达出口流量脉动分别下降了4.38 MPa和17.44%;马达噪声试验间接验证了仿真结果及优化方法的可靠性。Aiming at the problem that the rotary motor of a medium tonnage excavator produces large noise during operation,the swash plate axial piston rotary motor is taken as the research object,and the dynamic simulation of the axial piston motor is carried out by using the flow field simulation method.The influence of the structure and parameters of different damping groove on the piston plate on the pressure pulsation of the piston cavity and the flow pulsation at the outlet is explored.Combined with multi-objective sparrow search algorithm,the damping groove parameters are optimized,and the optimal damping groove parameters are obtained.The results show that the pressure and flow pulsation of the piston motor can be suppressed to some extent by increasing the depth and width of the damping groove in a certain range,and the U-shaped damping groove is superior to the triangular damping groove.After optimizing the U-shaped groove structure parameters,the pressure pulsation amplitude of the motor piston cavity and the motor outlet flow pulsation decreased by 4.38 MPa and 17.44%respectively.The reliability of the simulation results and the optimization method are indirectly verified by the motor noise test.
