Transient Dynamic Analysis on Key Components of the Port Handling Machinery’s Planetary Gear System

In order to seek the dynamic response of gear transmission with time-varying loads, this paper presents a transient dynamic analysis on key components of the port handling machinery’s planetary gear system, and a finite element model of gear system is established. In a period of load-time history, the gear meshing process under external loads’ effect is simulated dynamically and the gear’s transient dynamic response is analyzed systematically. The study can provide a reference for the full and accurate analysis of the physical state of the design objects, economic and reasonable structure design. Meanwhile, it can supply basic data for building fault diagnosis monitoring model of gear system.
