废气涡轮增压器叶片模态特性的探究

摘要

针对增压器常发生的由于叶片振动产生的叶片损坏现象，利用三维CAD建模软件对废气涡轮增压器涡轮叶片及压气机叶片进行建模，并采用有限元分析软件对其分别进行振型模态分析，找出发生共振的频率，为叶片的优化设计提供了理论依据。%Due to the turbocharger blade vibration ,the phenomenon of leaf damage often occurs .By using three-dimensional CAD modeling software ,the models of exhaust gas turbocharger turbine blades and compressor blades were set up .By using finite element analysis software ,the vibration modal analysis was conducted .The resonance frequency was identified .And a theoretical basis for the optimal design of the blades was provided .
