| 摘 要： | 声场分析是一类比较复杂的场分析问题。本文基于有限元法,建立了高强声波辐射场中某型转子叶片振动分析的有限元模型,并分别采用球面声波辐射,柱面声波辐射,平面声波辐射和均布声压等作用形式比较了叶片上振动的应力和声压分布。计算了3种叶片,数值计算的结果都与实验结果比较一致,定量揭示了高强声波对转子叶片的影响程度。

| Abstract: | Acoustic analysis is an important type of field analysis problem. Based on the finite element method （FEA）, the finite element model of a certain rotor blade in radiation field excited by high strength acoustic wave was built in this paper. And then, the stress and sound pressure distribution in the four different types of radiation fields were computed and compared to each other. The results of numerical simulation are consistent with the results of experimental tests for three types of rotor blades, which reveal the influence degree of rotor blade excited by high strength acoustic wave. |
