摘要
本文将有限元素法应用于径流式涡轮增压器涡轮叶片的振动分析,文中给出了较完整的理论分析和程序框图。用程序对18GJA涡轮增压器的涡轮叶片进行了分析,特别讨论了涡轮叶片几何尺寸对其振动特性的影响,并用激光全息摄影测量了涡轮叶片的振动特性。
This paper applies the finite element method to the analysis of vibration of turbine vanes of radial-flow turbine superchargers. Comprehensive theoretical analysis is made and a flow diagram is presented in the paper. This paper discusses with emphasis the effect of geometric dimensions of turbine vanes on their vibration behaviour, which is measured with hologram.
