Abstract

Aiming at the problems of complex vibration deformation and noise caused by bevel gear box drive system of cotton picker

taking core component of cotton picker-bevel gear system as the research object

the finite element coupling model of the bevel gear system is established based on NX environment

the numerical analysis of finite element coupling inherent characterist ics of the bevel gear system is carried out by application of NASTRAN solver

ultimately

some technical parameters of the bevel gear system

including:the first 20 order natural frequencies

total amplitude and the main vibrat ion mode

and output displacement nephograms related to all the frequencies are got.
