ABSTRACT
To improve the dynamic performance of non-pneumatic tire vehicle (NPTV) and recover the suspension vibration energy, a new self-powered electromagnetic suspension actuator matching non-pneumatic tire (NPT) with passive damping is proposed. Firstly, the mathematical model of the NPTV suspension system are established based on experiments. Secondly, the key performance parameters, passive damping and rated electromagnetic thrust, of the electromagnetic actuator are optimized, and its’ specific structure is designed. Then, a hybrid control strategy is proposed. Compared with the passive suspension, the body acceleration and suspension travel of NPTV are reduced by 9.09 % and 10.45 % respectively. Additionally, the proposed actuator can compensate the consumed power to realize self-power. Finally, a bench test is carried out, which verifies the effectiveness and superiority of the designed electromagnetic suspension actuator.
