중회귀모형을 이용한 유압펌프의 응력변형 해석

Abstract

This study analyzed the stress and deformation that occur in a gear-type hydraulic pump in response tovariations in pressure and temperature, identifying a correlation through multiple regression analysis. The resultsindicate that both the stress and deformation of the gear housing increased linearly with changes in temperatureand pressure. Pressure had a greater effect on the stress and deformation than temperature. In terms of stressvariation, the maximum stress measured was 72.7 MPa under extreme conditions (100.0 ℃, 20.0 MPa), which isconsidered safe because it is substantially lower than the yield stress (172.0 MPa).
