摘要

根据工程应用需求

从工程设计人员角度出发

阐明了结构设计参数、接触参数和动力学参数之间的相互影响关系。进一步建立了缘板阻尼结构的设计流程和优化方法

并给出了结构设计合理性的评估参数。某薄片式缘板阻尼结构的优化结果表明：通过优化缘板阻尼结构截面形状

可改善接触面应力的均匀程度

提高实际有效接触面积

实现在多个停留转速工况下更好的贴合状态

从而起到更好的振动抑制效果。

Abstract

The interactional relationship among the configuration parameters

contact parameters and dynamic parameters from the point of view for engineers and the need of engineering applications was discussed. The design process and optimization method of the under platform damper were further established to give the evaluation parameters for the rationality of the structure design. As the result of the optimization of a lamellar under platform damper

the uniformity of contact stress and the effective contact area can be improved by optimizing the section shape of the under platform damper. Meanwhile

the method can reach excellent damping effects for multiple operating rotation speeds.
