Abstract
In order to more accurately estimate the intrinsic mode of herringbone gear transmission box, fluid-structure interaction model of gear box and lubricants is established. Gear system natural frequencies and mode shapes is calculate out on the establishment of the fluid-solid coupling dynamics equations. The finite element models of gearbox and lubricating oil are build by ANSYS software, and the results of inherent characteristics are given. The top ten order natural frequency is distributed between 611.8HZand 2487HZ, and the first two order mode shape is respectively shown as the axial swing and horizontal swing. In order to verify the analysis results, the hammering method of single-input multiple-output (SIMO) is used to test gearbox structure modal. The results show that the mode shapes get from ANSYS analysis are consistent with the datas of experimental measurements, and the maximum deviation of natural frequency between experiment and theory is blew 15%. So it can be shown the fluid-structure interaction model in this paper is effective and reasonable.
