In order to reduce vehicle vibration and improve ride comfort handling stability, a nonlinear energy sink inerter (NESI) is designed by combing an (NES) for use in the seat suspension half-vehicle-seat (HVS) system; furthermore, model-free adaptive control (MFAC) method based on genetic algorithm proposed enhance dynamic performance of passive HVS system. The model active system coupled with NESI using MFAC established; its responses under pavement random shock excitations are acquired numerical evaluated seven evaluation indicators. efficacy demonstrated through comparative analysis original system, NESI, proportional integral derivative (PID) method. addition, influence installed position examined. results show that method, compared other three systems, root mean square (RMS) values body vertical acceleration, pitch front rear travel excitation smaller, corresponding peak amplitudes reduce, attenuation time shortens; RMS tire loading slightly increase, decreases, which reflects best among four systems shows effectiveness Furthermore, effect when it acts both suspensions.
