Abstract EN
A reduced-order dynamic model, based on three-dimensional (3D) finite element model (FEM) and component modal synthesis technique (CMS), was presented for simulating the dynamic behavior of the spur gear system.
The gear shaft and gear body were established via 3D elements to simulate bending and torsion of the gear system.
The CMS technique was used to generate a reduced-order model of a spur gear system.
A pair of mating teeth was assimilated to two different foundations (one for the pinion tooth and the other one for the gear tooth) linked in series by some independent springs, which was used to simulate the contact stiffness.
The validity of the proposed model was verified by static analysis, dynamic analysis, and experimental analysis.
The results show that the proposed model is an effective model.
In addition, the proposed model has also been applied to analyze spur gear spalling faults.
The results show that the dynamic response of the gear system is periodic vibration shock response due to the alternate meshing of single and double teeth.
When the spalling fault occurs, some shock responses with significantly enhanced amplitude will be generated as the result of contact loss.
