构建基于磁力弹簧和剪式座椅悬架的磁力座椅悬架,试验研究磁力座椅悬架的动态特性及调节特性。研究结果显示:磁力座椅悬架的位移传递率、位移传递率的峰值频率以及响应加速度均方根值均可以通过对磁力弹簧中电磁线圈端电压的调节得以改变。因此,将磁力弹簧引入到剪式座椅悬架中,研制一种垂向力位移特性呈非线性且垂向等效刚度可调的座椅悬架,并验证其是可行的,为刚度可调半主动磁力座椅悬架的深入研究奠定了基础。
The magnetic seat suspension based on the magnetic spring and the scissoring seat suspension is constructed, and the dynamic characteristics and adjusting characteristics of the magnetic seat suspension are studied. The results show that the displacement transfer rate, the peak frequency of displacement transfer rate and the root mean square of response acceleration of the magnetic seat suspension can be changed by adjusting the electromagnetic coil terminal voltage in the magnetic spring. Therefore, the introduction of a magnetic spring to the scissor-type seat suspension, the development of a vertical force displacement characteristics of non-linear and vertical equivalent stiffness adjustable seat suspension and verify that it is feasible for the stiffness Adjust the semi-active magnetic seat suspension in-depth study laid the foundation.
