超磁致伸缩作动器用于车辆主动悬架性能研究
|
摘要
在提出将超磁致伸缩作动器作为车辆主动悬架的力发生器方案的基础上,利用基于频响函数的子结构法建立了作动器/悬架系统耦合关系模型,揭示了超磁致伸缩作动器作动规律和车辆垂向振动之间的耦合性和参数匹配关系;将位移放大机构与超磁致伸缩作动器模型连接于车辆主动悬架模型中,在Matlab/Simulink中搭建基于超磁致伸缩作动器的车辆主动悬架控制模型,通过仿真对比分析主动悬架系统和被动悬架系统中的车辆振动响应控制状况,验证了将超磁致伸缩作动器用于车辆主动悬架中对车辆垂向振动进行抑制的效果。
We proposed that the giant magnetostrictive actuator was regarded as the force generator for active-suspension in vehicle. Based on that,the substructure technique based on frequency response function was used to build the coupling model of actuator and suspension system,which revealed the law of giant magnetostrictive actuator and the relation between the vertical vibration and parameter matching. Then,we connected displacement amplifier and model of giant magnetostrictive actuator to the active suspension model of vehicle,and built the control model of active suspension based on giant magnetostrictive actuator with Matlab/Simulink. Through simulation,the situation of vibration response of vehicle in active suspension and passive suspension was analyzed. Thus,the suppression effect of vertical vibration was proved,when the giant magnetostrictive actuator was used for active suspension of vehicle.
