前言弹性密封件的弹性液动问题(译注:所谓弹性液动润滑是一门考虑有弹性变形接触面的液体润滑作用的学科)是一个有待解决的问题,这是因为已经提出的理论的、实验的和数值计算的方法在实际应用上终究有现实的困难。本文总结了Bologna大学机械应用力学研究所的一些研究人员在弹性的密封件弹性液动方面对橡胶力学特性、光弹性和数值计算技术的模拟所做的工作。 Introduction The problem of elastic fluidity of elastomeric seals is an issue to be solved because the so-called elasto-hydrodynamic lubrication is a subject that takes into account the liquid lubrication of elastically deformed contact surfaces because of the theoretical, experimental There are practical difficulties in practical application of numerical methods. This paper summarizes the work done by some researchers at the Institute of Mechanical and Applied Mechanics at the University of Bologna on the simulation of rubbery mechanical properties, photoelasticity and numerical techniques in the case of elastomeric elastohydrodynamic seals.
