External Gear Pump Model and Simulation

Abstract:

This paper describes the development of gear pumps and the main causes of noise,and establish the overall dynamic model of external gear pump,mainly including the trapped oil model,the gear mesh model and the shell model and then go on with simulation analysis and research.Through establishment the gear pump model,it is benefit for predicting the gear pump trapped oil pressure and studying the impact of parameter changes on the pressure,and getting the natural frequencies and model shapes of the gear pump structural system,so that we can analysis external gear pump vibration and assess gear pump design optimization,while helping to find the effective measures to control gear pump noise and ease trapped oil phenomenon.
