摘　　要：文章介绍了阶跃激励法、正弦激励法、脉冲激励法三种动态扭矩计量测试方法,并对不同时间做的两次试验进行了对比,得出的数据相差在3%以内,证明了上述动态特性的测试方法具有重复性和追溯性,可用作扭矩传感器动态特性的测试。This paper introduces the measurement method of dynamic torque particularly which includes step excite, sinusoid excite and impulse excite, then contrasts the two experimental result made in different time of which the discrepancy is less than 3 percent, and proves these method are repeatable and retroactive which can use for measuring the performance of torque transducers.

关 键 词：动态扭矩 测试方法 阶跃激励 正弦激励 脉冲激励
