Abstract

The influence of design factors on cylinder liner deformations and relationship among them are investigated. The wedge slope of liner flange, preload force and friction coefficient are chose as the investigation factors. Finite element model of the assembly consisting cylinder liner and block was set up. The displacement and stress results of the model are calculated through 16 computational schemes based on orthogonal test design theory. Influence of the above-mentioned factors on the deformation of cylinder liner and numerical relations are analyzed according to the calculation results. Calculation results showed that decreasing the preload force is the most important factor to decrease the maximum stress in cylinder liner, followed by increasing the wedge slope of the liner flange. Decreasing the friction coefficient has relatively less influence on the change of stress in cylinder liner.
