组合碟簧式核级阀门电动装置转矩控制机构的研究

摘要

简述组合碟簧式核级阀门电动装置转矩控制机构的工作原理。对转矩控制机构的主要件进行了受力分析，推导出组合碟簧设计的理论计算公式。利用ANSYS有限元分析软件对碟簧的应力与变形进行了分析，分析结果与理论计算结构吻合。理论计算和有限元分析方法都对今后设计适用于核级阀门电动装置的转矩控制机构有一定的参考价值。%The paper introduces working principle of nuclear grade valve actuator’s torque control mechanism with combined disc spring. It analyses the mian parts of torque control mechanism detailedly,and also deduces the theoretic computational formula for designing the combined disc spring. Then it analyses the stess and transmogrification of the disc spring using the ANSYS. The method with finite element analysis and theoretic calculation can be introduced to the future design of disk spring that can be the same with the torque control mechanism of nuclear grade valve actuator derivate.
