“…[22][23][24] Although the vibration isolation measures can optimize the vibration response of the system and cannot eliminate the vibration, the crankshaft vibration will still be transmitted to the gears of the gearbox, so it is the source of torsional vibration in the rest of the transmission system. 25 The influence of engine damping elements of the transmission system is tantamount to decrease the critical speed, generally lower than idle speed. However, the residual vibration will still excite extra low-order modes of EMT torsion.…”

The high-power electromechanical transmission (EMT) system is a typical dual-mode hybrid power transmission system. The torque fluctuation of internal combustion engine causes serious shock and vibration problems of EMT. Suppressing torsional vibration based on high dynamic motor torque regulation is an important way to improve the working life and stability of EMT system. First, a lbased on the lumped parameter linear dynamic model,the torsional vibration characteristics are analyzed. Second, a fluctuating speed estimation method is proposed based on the uniformly accelerated motion model and linear regression, and a digital high pass filter is designed. Then, a master-slave coupling active torsional vibration control strategy is proposed, and a PD control algorithm based on speed feedback is designed. The variation rules of control parameters is analyzed. Finally, the control effect is verified by experiments. The results show that the lever coefficient K ab and differential coefficient K d of master-slave control can change the natural frequency of torsional vibration of the system, thus significantly changing the vibration response of the system. Selecting appropriate control parameters can achieve peak clipping of EMT torsional resonance.
