Developing a Simple Computer Model for Fluid Coupling

Abstract

Fluid coupling is regarded as an essential mechanism in semi-automatic transmission systems which are used in most new and advanced heavy vehicles . It has already replaced the ordinary mechanical coupling and clutch units . It has a great advantage of reducing torsional and transverse vibrations. In addition , changing gear ratios can be accomplished easily without difficulty . Curve fitting technique with the aid of computer has emerged as a compelling animation technique . Yet current approaches to fluid coupling simulation are inefficient or can't handle some relevant scenarios robustly . A practical results of a certain fluid coupling has been chosen which were used in " Reem " buses and were utilized by the State Company for Automotive Industries at Iskanderia in Iraq . However , and when modeling the complete engine transmission system , these practical results were not easy to follow and apply . The aim of this work is to develop a simple and flexible model for a fluid coupling . The object is to obtain a simple relation among fluid coupling main controllable variables , so that is can be utilized easily in a future comprehensive model of engine-transmission system used for dynamic analysis.
