摘要: 研究飞轮密封罩的结构优化设计方法.首先综合分析了利用凸弧和凹弧构建密封罩结构外形曲线的设计思路,在此基础上提出凹凸弧方案;进而据此推导出凹弧弓高极值,构建一系列飞轮密封罩结构模型;最后以某飞轮密封罩为分析对象,利用有限元技术研究其稳定性等性能随外形参数的变化规律.这种新的设计思路可对类似产品结构的设计提供指导.

Abstract: Optimization design method for flywheel’s sealed cover is studied in this paper. Above all, the design schemes for constructing outline curve of sealed cover using convex concave arcs are comprehensively analyzed. Then a scheme for designing the outline curve consisting of concave arc and convex arc is proposed. Based on the above, the extremum values of arcs are derived and a series of structural models are constructed. Finally, taking the sealed cover of a flywheel as an example, the varying rules of the stability corresponding to the outline parameters are studied using finite element approach. The new design scheme can provide instructions for the design of similar structures.

Key words: flywheel, optimization design, finite element, stability, convexconcave arcs
