Abstract

A ZJ-type high pressure lubrication pump is analyzed by multidisciplinary design optimization (MDO) method, where data are sampled via optimal Latin hypercube experiments, and the response surface models (RSMs) for the plunger piston and cylinder body of the pump are built. Lightweight design of the piston mechanism is conducted by using the improved collaborative optimization with a relaxation factor combined with sequential quadratic programming (SQP) algorithm. The results show that the approximate model accelerates the opimization speed greatly, the mass of optimized plunger mechanism is reduced by 8.03%, and MDO can effectivelly deal with the coupling factors between the different components to reduce mass while the stress constraints and fatigue life are met.
