转子叶片缘板阻尼结构设计方法

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.
