摘要
基于流固耦合4-方程模型推导了燃油管道流固耦合振动直管单元的轴向振动和横向振动场传递矩阵,引入弯曲因子推导了弯管点传递矩阵。通过传递矩阵法对航空发动机典型燃油管路L型弯管和等长直管在不同边界条件下进行流固耦合振动模态分析。
The field transfer matrixes of fuel pipelines for axial vibration,transverse bivration and the point transfer matrixes of the elbow is derived based on FSI vibration 4- equation model.The elbow point transfer matrix is established by introducing bending factor.The modal analysis of fluid-Structure interaction vibration of a typical aero-engine fuel piping L-bends and straight pipe of equal length in different boundary conditions is studied by die transfer matrix method.
