Abstract
In this paper, theoretical analysis of effective particles of long-chain polymer on performance improvement of the human joint is presented. mathematical model depended on a laminar steady flow of synovial fluid that it contains on hyaluronic acid between articular cartilage in( hip- knee-ankle) joint, where Reynolds equation governing the fluid film pressure was derived and solved analytically. Quasi-statics equilibrium equation determined friction force during daily activities, the influence of film thickness and squeeze action, length of chain and speed on the squeeze film characteristics were discussed. It has been found that the effect of the decreased film thickness of particle leads to an increase in the load carry capacity, friction force and decreased flow rate. It is observed that the effect of length of a particle on pressure film between articular surface with sliding motion is to increase.
