Validation Of Lateral Gap Leakage Objective Function For Use In Multi-Objective Optimization Of Gerotor Pumps, Kevin Cohen, Andrew Robison, Andrea Vacca

The Summer Undergraduate Research Fellowship (SURF) Symposium

Gerotor pumps are a common pump choice used in the automotive, agricultural, and construction fields for their low cost and durability. Recently, demanding applications have called for significant design improvements in gear geometry. To address these design challenges, multi-objective optimization has been applied to gear geometry. The goal of this work is to introduce minimizing of lateral-gap leakage to the multi-objective optimization. An objective function for evaluating lateral-gap leakage based on 1D, pressure driven flow is proposed. This simplified approach is compared to CFD simulation solving of Reynolds equation with two pressure boundaries. Comparison of the simplified relation and the …

Design Of A Test-Rig For Gerotor Pump, Weijin Qiu, Andrea Vacca, Matteo Pellegri

The Summer Undergraduate Research Fellowship (SURF) Symposium

Gerotor pumps are a kind of fluid power machines widely used in the automotive field, especially for fuel injection as well as lubrication. To improve the performance of these units, virtual prototyping is necessary to decrease time and cost related to trial and error. Within this research a simulation model for Gerotor units has been developed with the aim of predicting accurately the performance of a generic unit. The model can accurately predict the system behavior regarding mechanical and volumetric losses by considering real machining tolerances and their interactions. Ultimately, this model should help to design new generations of Gerotor …
