摘　　要：针对经典JT15D航空发动机模型,利用Actran软件中的Actran/TM模块和Actran/DMG模块分别对该发动机进气道声传播特性进行仿真计算。仿真基于二维模型展开,通过TM模块研究了不同网格类型、网格尺寸等参数对仿真结果的影响。此外,建立了基于Actran/DMG模块的二维模型仿真,并与Actran/TM模块二维仿真数据进行了对比研究,以确立该软件中2种仿真模块在航空发动机进气道声传播仿真方面的特点。Based on the classical JT15D aero engine model,Actran/TM module and Actran/DMG module in Actran software are used to simulate the acoustic propagation characteristics of the engine inlet.The simulation is based on two-dimensional model expansion.TM module is used to study the influence of different mesh types and mesh sizes on the simulation results.In addition,a two-dimensional model simulation based on Actran/DMG module was established,and a comparative study was conducted with the two-dimensional simulation data of Actran/TM module to establish the respective characteristics of the two simulation modules in the software in the aero engine inlet acoustic propagation simulation.
