摘　　要：某企业采用ABB六轴机械手实现恒力、恒行程打磨结构件焊缝,因打磨过程中振动较大,需避开设备的固有频率,还需对打磨过程中引起的受迫振动进行分析。因此,采用SolidWorks对六轴工业机械手进行建模,利用ANSYS Workbench软件对其模态振型和谐响应特性进行分析,得到了模态振型数据和简谐响应曲线,仿真检验了该工业机械手的最大振幅以及受迫振动下是否能满足打磨精度要求,可为实际工况应用提供数值参考。An enterprise uses ABB six axis manipulator to realize constant force and constant stroke grinding of structural weld.Due to the large vibration in the welding seam grinding process,it is necessary to avoid the natural frequency of the equipment and analyze the forced vibration caused by the grinding process.Therefore,this paper uses SolidWorks to model the six axis industrial manipulator,uses ANSYS Workbench software to analyze its modal shape and response characteristics,obtains the modal data and harmonic response curve,to simulate and test the maximum amplitude of the industrial manipulator and whether it can meet the grinding accuracy requirements under forced vibration.Finally,it provides a numerical reference for the practical application.
