摘要

摘要: 运用有限元和动力学分析方法分析了新开发的大功率高速弹簧离合器在不同摩擦系数下的接合动态特性;在Abaqus平台上建立了由弹簧和输入输出壳体组成的弹簧离合器三维有限元模型,分析得到了不同摩擦系数下离合器的响应时间、接合时间、弹簧内外圈的Mises应力、径向位移。结果表明,设计的变截面弹簧离合器响应速度快,弹簧稳态接合后的Mises应力分布较均匀,且弹簧中部圈还未完全与壳体内壁接触,离合器承载能力还有一定裕度。此外,弹簧与壳体间摩擦系数对离合器接合时间、响应时间影响不大,对弹簧Mises应力有影响,对弹簧的径向位移影响明显。

Abstract: Both the finite element method and the dynamics method are conducted to investigate the engaging characteristics of new developed high power and high speed spring clutch in different friction condition. The threedimensional finite element analysis model for spring clutch,which consists of spring,input and output housing,is established via Abaqus platform. Through analysis,response and engaging time of clutch inside and outside ring and Mises stress and radial displacement of spring are obtained. The results illustrate the response of the clutch is quick,the steady state Mises stress of the spring is well-distributed and the radial displacement of the spring is not completely contacted with housing. The loading of the clutch still has some allowance. The engaging and response time of the clutch is not influenced too much by the friction coefficient. The friction coefficient influences the Mises stress of the spring and radial displacement of the spring.
