电动主动吸振器的设计及特性研究
|
摘要
设计了一种用于动力总成振动控制的电动主动吸振器。利用有限元和正交法,以最大气隙磁感应强度为目标,确定了电动作动器的磁路结构,并仿真计算了该作动器在不同电流输入下产生的电磁力。设计了片状弹簧的结构,并分别计算和测试了其轴向刚度。对该电动主动吸振器进行性能测试,结果表明,其驱动力大小与电流有效值呈准线性关系。
An electrodynamic active vibration absorber applied to powertrain vibration control was developed. In order to make magnetic induction intensity of air gap as large as possible, finite element method was combined with orthogonal method to determine the magnetic circuit's structure of the electric actuator. Then, the actuator's electromagnetic forces generated by different currents were simulated and calculated. The leaf spring's structure was designed and its axial stiffness was calculated and tested. Finally, this absorber's performance was tested. The result shows that its driving force is quasi-linearly related to the current effective value.
