摘要:

汇流环安装于具有相对转动的内、外环道之间,受到内、外环道的预紧压缩,形成与环道之间的微小面积接触,并通过接触面实现电传输.为了明确薄壁圆柱形滚动汇流环的装配力学特征及其压缩状态,基于汇流环装配后产生的变形状态,运用弯曲力学理论建立汇流环装配压缩后的弯曲变形模型,结合赫兹接触理论以及电接触理论得出汇流环压缩变形、接触电阻以及结构尺寸三者之间的关系.根据装配约束条件,得出汇流环预紧压缩量的预设范围.通过设计实例的计算分析与ABAQUS有限元验证,其结果表明有限元仿真结果与理论模型的计算结果相差微小.汇流环装配压缩的力学模型及其预设范围具有良好的合理性与正确性,能够为滚动汇流环的优化设计提供重要参考.

关键词: 滚动汇流环装配压缩结构设计约束条件仿真    
Abstract:

The collector ring under compression is installed between a exterior orbit and a interior one that produces contact zone between ring and orbits and obtains electro-transport.Aiming to define character of rolling collector ring mechanics and its compression state,based on the distortion of ring after assembling,a bending deformation model of ring under compression was established with bending principle. Hertz contact theory and electrical contact theory were used to obtain the relationship among contact deformation,contact resistance and design size of the ring.According to the constraint conditions of assembling,the rational preinstalling and discriminant range of compression of collector ring were determined.By means of calculation and validation of design living example and simulation of software ABAQUS,the result of mechanics after simulation almost kept the same with calculation of theory model.The research provides reference for the development and optimum design of rolling collector ring.

Key words: rolling collector ring    assembling compression    structural design    constraint condition    simulation
