摘要

为了研究阻尼器惯性质量对汽车馈能悬架系统减振性能及馈能特性的影响

优化电磁阻尼器选型

根据汽车悬架系统动力学方程推出阻尼器惯性质量表达

并引入惯性质量

以悬架系统车身加速度、悬架动行程和车轮动变形量作为系统输出

建立了精确化馈能悬架系统的状态空间模型

通过状态空间模型系统输出的频域传递特性分析了惯性质量等级对悬架系统主要性能的影响。仿真结果表明:随着阻尼器等效惯性质量的增大

悬架系统平均馈能功率降低; 虽然低频段主要性能指标的幅频传递特性有小幅改善

但中频段传递特性恶化严重; 过高的阻尼器等效惯性质量会引起悬架系统总体性能恶化。通过1/4悬架系统台架实验对仿真结果进行验证

结果表明:在相同激励条件下

电磁阻尼器惯性质量使馈能悬架系统平均能量回收功率产生最高44%的衰减; 较高等级的惯性质量导致悬架系统关键性能指标传递特性在中频段产生不同程度的恶化

共振频率发生小幅前移

悬架系统总体性能变差。实验结果验证了仿真结果的正确性。

Abstract

A precise state space model of regenerative suspension system including inertial mass is established to study the influences of the damper's inertial mass on the vibration insulation performance and energy recovery performance of the vehicle regenerative suspension system and to optimize the electromagnetic damper selection. The damper's inertial mass is derived from the dynamic equation of the vehicle suspension system

and the acceleration of the suspension system

the suspension travel and the wheel's dynamic deformation are used as outputs of the system. The influence of the inertial mass level on the main performance of the suspension system is analyzed by using the frequency domain transmission characteristics of the outputs of the state space model system. Simulation results show that the average energy recovery power of the suspension system decreases with the increase of the equivalent inertial mass of the damper. Although the amplitude-frequency transmission characteristics of the main performance indicators in the low frequency band are slightly improved

the transmission characteristics in the middle frequency band deteriorate seriously

and excessive inertial mass of the damper will cause the overall performance of the suspension system to deteriorate. The simulation results are verified on a 1/4 suspension system bench test. Results show that under the same excitation condition

up to 44% attenuation of energy recovery power is caused by the inertial mass of the electromagnetic damper and that higher-level inertial mass causes the transmission performance of the key performance indicators of the suspension system to produce different degrees of deterioration in the middle frequency band

the resonance frequency is slightly shifted forward

and the overall performance of the suspension system deteriorates. The experimental results verify the correctness of the simulation results.
