摘要
为了提升被动悬架的道路振动响应特性,提出一种并联螺旋飞轮运动转换器的新型悬架系统。对螺旋飞轮运动转换器的动力学特性进行了分析,在传统机电比拟理论的基础上,采用自由电容元件来比拟封装螺旋飞轮的运动、转换和质量特性。采用机械网络综合的方法,建立并联运动转换器的车辆悬架状态空间模型,进行参数优化设计以分析悬架对道路振动激励的最优控制性能。对实例性能分析表明,所提出的新型悬架可以有效提升综合性能,为悬架的设计提供了新的思路。
In order to improve the response characteristics of vehicles under the road vibration excitation,a novel suspension system with the spiral flywheel motion transformer was presented.The dynamic characteristic of the motion transformer was analyzed.In the analysis,based on the traditional mechanical-electrical analogy theory,a free capacitor component was proposed to encapsulate the motion,transformation and mass characteristics of the spiral flywheel.The mechanical network synthesis method was then used to construct the state-space model of the novel suspension.Parameters of the suspension were optimally designed so as to achieve the optimal vibration control performance.The result shows that proposed suspension is of better performance,which provides a novel approach for design of vehicle suspensions.
