Application of SolidWorks AMESim - based Updated Simulation Technique to Back-flow Analysis of Trochoid Hydraulic Pump for Lubrication

摘要

In this paper, we deal with the Gerotor pump which will be referred to as "trochoid pump," hereinafter since it has been widely used for the transmission part of a automobile. Usually, the simulation of trochoid pump has utilized a professional analysis program or language such as CFD (specifically CFX) or C-code (e.g. C++) which is not an easy tool for afield engineer. But the field engineer based on his experience has a hurdle in modifying the flow model according to the need of a customer. To cope with this problem, in the paper of Kim et al. [3] in WORLDCOMP 2012 (CSC 2012), we have presented how to establish the flow model of a trochoid pump by using the most popular 3-dimensional (or 3D) modeling tool SolidWorks and a hydraulic analysis program AMESim. For this model, we have figured out the clearance problem which was neglected in the paper of Kim et al. [3]. In this paper, we will update Kim's flow model in order to solve the clearance problem by incorporating Jang's formulation [4] into the SolidWorks model. The practical excellence of updated simulation technique proposed in this paper will be verified to be compared with experimental results.
