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。
In this paper, the finite element method is applied to the vibration analysis of radial turbocharger turbine blades. In this paper, a more complete theoretical analysis and block diagram are given. Turbine blades of 18GJA turbocharger were analyzed by program, especially the influence of turbine blade geometry on its vibration characteristics was discussed. The vibration characteristics of turbine blades were measured by laser holography.
