For improving continuous independent pulse measurement accuracy and satisfying requirements of large-scale samples processing, design the processing method for torsion pendulum displacement data in continuous independent impulse measurements. Analyze the actual vibration process, establish torsion pendulum displacement equation, use LM method and displace data to acquire fitting parameter, write practical program, calculate impulse by calibration parameter and verify it by example. The results show that the method can effectively improve the efficiency of continuous independent impulse measurement with high accuracy. It has strong anti-interference ability and engineering application value in complex environment.
