Abstract

A dynamic model for geared multi‐body system containing gear, bar and shaft is proposed and a new gear element is particularly developed based on a specific finite element theory. The gear element can take into account time‐variant meshing stiffness, the gear errors, and the couplings between the torsional and the lateral vibrations of gears. The accuracy and reliability of the gear element are confirmed by comparing the simulated with the experimental results of rotational vibration accelerations. A gear–bar mechanism composing one sun gear, one planetary gear and two bars is simulated dynamically. The influences of non‐uniform gear speed, time‐variant meshing stiffness and bar stiffness on the dynamic behaviours are investigated. Copyright © 2002 John Wiley & Sons, Ltd.

The purpose of this paper is to present a simple approach for eliminating the &&dependent'' torsional angles existing in the reduction gears of a gear-branched system so that this system may be modelled as an equivalent straight-geared (or direct-transmitted) system.
