- Abstract
Based on FEM/BEM method, the analysis model of vibration and acoustic radiation properties of planetary reducer box is established in this paper, and the vibration and acoustic radiation properties of planetary reducer box is analyzed. First of all, the finite element analysis model is established in ABAQUS. Secondly, the acoustic radiation boundary element model is built through the VA-one, then calculate the sound pressure distribution of the surface and sound field of the box, the noise spectrum and field and modal contribution degree of radiation noise of the box is also calculated. And the influence law of the main structural parameters on radiation noise properties is studied, which can provide technical support for the structural scheme design of planetary reducer box.
