摘要

针对高温条件下磁流变液流变效应下降,造成剪切应力变化不可控甚至传动失效等问题,根据磁流变液的流变特性以及形状记忆合金的感温特性,设计了一种磁流变液和形状记忆合金复合传动装置,在温度较低时依靠磁场控制的磁流变液来传递转矩,在温度升高磁流变液性能下降时,利用形状记忆合金弹簧辅助传力。对所设计的传动装置进行传力分析,推导出传动装置传力公式。研究结果表明,该复合传动装置在外加磁场和外界温度控制下工作,在高温环境下,传递的转矩仍能保持连续、可控,提高了传动装置的稳定性和工作效率。

Abstract

The magnetorheological effect of magnetorheological fluid reduce under a high temperature condition,which causes so many problems like the uncontrollability of the variation of shearing stress,and even failure of the transmission device.Based on the rheological property of magnetorheological fluid and the temperature characteristics of shape memory alloy,a composite transmission device of magnetorheological fluid and shape memory alloy is designed,which rely on magnetorheological fluid to transfer torque under a lower temperatures condition,shape memory alloy spring assisted power transmission when the magnetorheological performance reduce under a high temperature condition.The performance of drive force transmission device is analyzed,and the formula of power transmission of transmission device is derived.The study results show that the composite transmission device can work at the external magnetic field and the temperature control,the torque can maintain continuous,controllable under a high temperature condition,the stability and efficiency of transmission device are improved.
