| 摘 要： | 根据某大型立式行星传动齿轮箱的结构和安装特点，基于FEM法建立了该齿轮箱的和有限元模型，对其进行了振动模态分析，计算了其模态频率和稳态不平衡响应；基于BEM法建立了该齿轮箱的外声场边界元模型，导入了齿轮箱振动稳态不平衡响应结果作为声学边界条件，对辐射声场进行了数值计算和仿真分析。通过对齿轮箱进行现场振动和噪声测试分析，得到的测试结果与理论计算结果较为一致，表明了理论计算的可行性和准确性

| Abstract: | According to the structure and installation of large vertical planetary transmission gearbox,a finite element model were established based on FEM to carry out the vibration modal analysis and calculate the modal frequencies and stationary unbalance responses.A boundary element model of the sound field surrounding the gear box was established based on BEM to calculate and simulate the radiated sound pressure with the results of stationary unbalance responses.The results of testing and theoretical calculation are consistent,which indicates the rationality and accuracy of the theoretical calculation. |
