![]() The equations of motion are established based on differential quadrature finite element method (DQFEM). The elastic deformations of thin-web are included in the potential energy of time-varying mesh process. A universal method to derive the kinetic energy of rotating gear rotor is proposed based on multi-body dynamics theory and small deformation assumption. The shaft, disc and ring structures are simulated based on Timoshenko straight beam theory, Mindlin plate theory and Timoshenko curved beam theory, respectively. A dynamic model of spur gear pair combined with elastic shaft–disc–ring rotor is proposed to study the effect of web thickness on the dynamic characteristics. ![]()
