Abstract:

We present a new time-varying mesh stiffness model using polynomial function with regard to the time-varying mesh stiffness of the high-bevel gear of a radar device. By analyzing the revolution speed, load torque and damping factor, we build the mesh stiffness model and the nonlinear dynamic equations of the high-bevel gear. We compare the proposed mesh stiffness model with traditional rime-varying mesh stiffness model of multi-order harmonic superposition and reference data model of time-varying comprehensive stiffness. It is shown that, with small damping and overload, the proposed model is much closer to the actual characteristics of the time-varying stiffness. This model lays a foundation to study the gear transmission dynamics, such as vibration damping, noise reduction, smooth transmission and other aspects with small damping and overload.

Key words: technology of instrumen and meter, time-varying stiffness model, high-spiral bevel gear, polynomial application, nonlinear dynamic
