Abstract: A novel vibration method， the master-slave distributed vibration test method， was proposed. Aiming at its control re? quirements， an online waveform replication technique for vibration loads was developed and an integrative prototype system with measuring and controlling functions was constructed. Therein， a signal processing method of frame segmentation and reconstruc? tion was proposed for solve the problem that time waveform replication for long-duration continuous vibration loads. A method for dynamic transfer function estimation based on sample database construction and weighted average was proposed to reduce the influ? ence of nonlinear property on control precision. A spectrum correction method was introduced to improve the frequency domain con? trol accuracy. A test with 1 master vibrator and 2 slave vibrators was performed using the developed online vibration load replica? tion control technique， and the results show that the technique has a high replication precision in both time domain and frequency domain， has a subsecond overall delay time， and has a subpercent overall root-mean-square error. The technique can provide a key technique for supporting online distributed vibration tests.
