Abstract

Abstract: In this paper, penalty-finite element formulation is established by penalty function for incompressible rubber-like materials (D-0.5).The numerical examples have been calculated. The procedure is shown to be effective and convenient.The calculated values of contact pressures of mud pump piston show good agreement with the experimental data.

摘要： 本文罚函数的概念,建立适用于不可压缩(橡胶类)材料v→0.5)的罚有限元的计算表达式。对实例进行计算表明:这种方法是有效而方便的.泥浆泵胶活塞的接触压力的计算值与实验基本相符。
