摘要
利用有限元法推导某舰用燃气轮机高压涡轮压气机转子的传递矩阵,并建立转子的多体系统传递矩阵模型。通过算例证明,该方法计算准确,为用有限元法和多体系统传递矩阵法求解燃气轮机转子学问题提供了新思路。
In this paper,stiffness matrix of high-pressure compressor rotor of gas turbine was deduced by using finite element method,and then the transfer matrix method of multibody system model of the rotor was builded.The calcualtion results proved that this method has highly calculating precision,and it is simple.This method also provide conference for solving rotor problem by combining finite element method and transfer matrix method of multibody system.
