Abstract

It is generally accepted that the simple epicyclic gear train has six possibilities for connecting it with both engine and load . The aim of this paper is to find the optimum connection method for dynamic analysis . Therefore , it is required to calculate the equivalent inertia for the epicyclic for six cases , and then finding the least value for the equivalent inertia owing to the large load inertia used in heavy vehicles .This will lead to a quick response for the vehicle . The main variable is the epicyclic ratio ( R ) , which is the ratio of teeth number of annular gear divided by teeth number of sun gear . Two values of ( R ) have been used ( R=2 ) and ( R= 4 ). It has been found that the optimum method for dynamic connection is when engine is connected to sun gear , while load is connected to carrier . This connection has been utilized practically for many decades . However , the actual and theoretical reason has not been fully dynamically analyzed and understood . Even using other five possibilities for connection have not been studied . It is hoped that this analysis will be useful in future application for connecting simple and complex epicyclic gear train in steady state and dynamic analysis .
