摘要
传递矩阵法因其简便、快捷,已被广泛应用于机械、航空和航天等领域。本文以航空发动机低压转子临界转速分析为例,对传递矩阵法在结构振动响应分析中的应用方法和分析步骤进行了详细的介绍,并给出了某型发动机低压转子在不同支承刚度下的临界转速。
Transfer matrix method has been broadly used on mechanics, aviation and aerospace for its simple and smart solution,A detailed analysis and procedure of transfer matrix method on structural vibration response are introduced by an example of critical speed analysis on the LP shaft of aeroengine, and the critical speed of LP shaft is given with different support stiffness.
