The invention discloses an apparatus and method for analyzing dynamic torsional stiffness of a harmonic reducer. The apparatus comprises an AC servo motor with a coding disc. An output shaft of the AC servo motor is connected with an input shaft of a harmonic gear reducer through a coupling. An output shaft of the harmonic gear reducer is connected with one end of a torsion sensor, and the other end of the torsion sensor is separately connected with a torsion spring and a rotary coding disc. The apparatus further includes an AC motor servo amplifier, a signal generator, an A/D conversion data acquisition card, a computer and a code disc counting solution card. The output torsional stiffness of the harmonic gear reducer can be solved by measuring angular displacement signals at input and output ends of the harmonic gear reducer and a load torque signal at the output end and by running a corresponding algorithm. 本发明公开了种谐波减速器动态扭转刚度分析装置与方法，包括交流伺服电机，所述交流伺服电机自带编码盘，所述交流伺服电机的输出轴通过联轴器与谐波齿轮减速器的输入轴连接，所述谐波齿轮减速器的输出轴与扭转传感器
