摘　　要：对伺服电机的转矩波动性能指标进行测试时,伺服电机安装在测试台上,结构件的精度及安装同心度的偏差带来了附加转矩,需要去除附加转矩才能得到伺服电机的实际转矩波动值。本文介绍了基于时-频域变换的方法去除附加转矩的应用,以及采用LabVIEW软件的设计实现,经过仿真验证,并应用到实际测试系统软件中,取得了满意的效果。Torque ripple of the servo motor performance testing, servo motor installed on the test bench, the precision of the structure and installation of the concentricity deviation will lead to additional torque, remove additional torque is needed to get the actual values of torque ripple servo motor. This paper introduced the method based on time-frequency transform applied to remove the additional torque, and the use of LabVIEW software design implementation, through simulation and applied to the actual test system software, satisfactory results have been achieved.
