摘要
为有效回收车辆悬挂振动能量,对馈能影响因素及相互间的关系进行分析。建立复合式电磁悬挂系统(composite electrical-magnetic suspension system,简称CESS)动力学及馈能电路模型,采用功率流的方法分析悬挂系统的能量输入、输出及耗散关系。在考虑传递效率的条件下,分析电阻比、激励频率及振幅对馈能效率与馈能功率的影响。讨论了减振指标及馈能性能之间的关系,通过台架试验分析了外接电阻与悬挂相对运动速度对馈能性能的影响。结果表明:采用功率流的方法可有效分析悬挂能量流动关系,馈能效率和馈能功率受电阻比、激励频率及振幅等因素影响;悬挂系统不能同时满足最大馈能效率和最大馈能功率,悬挂系统减振及馈能性能存在一定的相互制约关系。
In order to effectively recycle vibration energy of vehicle suspension,the factors concerning the recycling and their relationship are analyzed.First,the dynamics and energy recovery circuit model of a composite electrical-magnetic suspension system(CESS)are constructed. Then,the relationship among the energy input,output and dissipation of suspension system is discussed.The influence of resistance ratio,excitation frequency and amplitude on energy recovery efficient and energy recovery power is analyzed when considering transportation efficiency.Further,the relationship between vibration attenuation and energy recovery performance is discussed,and the influence of circumscribed resistance and suspension relative kinematic velocity on energy recovery performance is analyzed.The results indicate that the proposed method can analyze the flow relationship of suspension energy effectively use the method of power flow;energy recovery efficiency and energy recovery power are influenced by multiple factors like resistance ratio,excitation frequency and amplitude;Suspension system fails to contemporarily reach the maximum ener-gy recovery efficiency and maximum energy recovery power,and the vibration attenuation and energy recovery performance of suspension system constraint each other.
