新型空间大功率滚环热分析
Thermal Analysis of Novel High-power Roll-ring
摘要
Abstract
Aimed at the desire of high-power transferring,longer life and higher reliability,some typical characteristics of novel roll-ring,such as roll-ring blocking,multi-flexure and accordant movement are introduced in the paper.Then,the model of contact resistance and rolling attrition moment is established,and,the resistance heat and friction heat under the roll-ring's key parameters are investigated theoretically and compared in the paper.Lastly,the steady-state thermal numerical analysis of different current transferring in vacuum environment is finished.And for improving heat characteristic to enhance transferring power,some comments on the structure design and material are given and the future research direction is indicated in this paper.关键词
