摘要
本文将动态子结构方法中链式加载技术与群论算法相结合,提出环向固连带冠叶片动力特性分析的一种新方法。文中列出了分析步骤与具体公式,并有实例的计算结果。该方方法适用于研究具有带冠叶片的单级转子中,“冠”的整体效应。
An advanced method has been presented for analysing the dynamic behaviour of annular cascade shrouded blades used in compressor and turbine rotors of engines. The method may be considered as the combination of chain loading technique and group algorithm. It is applicable to investigate the complete effect caused by blade shrouds. Its general analytical procedures and concrete equations are shown in the paper. The extension of dynamic analysis for structures which have both periodically cyclo-symmetric and annular cascade characteristics can be realized. Under the precondition that the computational accuracy is ensured, this method shows reliability, practicability and remarkably economic benefits.
