一种电磁驱动主动头枕的设计与研究

摘要/Abstract

摘要：

设计了一种电磁驱动主动头枕,采用机电结合的方式,通过连杆机构实现头枕的快速前移。为使头枕具有良好的运动特性和动力特性,设计了驱动滑块的位移规律并反推出电磁驱动器的控制电压。采用分时分区段能量守恒方法,得出了电压曲线中关键点的理论值;通过测试得到了电压试验值,将其与理论值进行对比,结果发现二者的电压变化规律相同。

Abstract:

An electromagnetic driving active headrest was designed, which combined mechanics and electricity to achieve the fast forward displacement of the headrest with the link mechanism. The displacement law of driving slider was designed and the control voltage of electromagnetic actuator was derived in order to make the headrest with good performance of movement and dynamics. The theoretical values of the key points in the voltage curve were obtained by using the energy conservation method in every time and displacement partition. The test values of voltage were obtained through experiments. Compared with the theoretical values, the change rule of them is the same.

Key words: rear end collision, active headrest, mathematical model, energy
