In these days, how to use hybrid system technology , which has been successfully used in automobiles, in construction machinery become an issue. The primary focus of this study is to construct a computational model that can be operated like a conventional hydraulic machine, by using AMESim the hydraulic analysis tool. Then by adding compound type hybrid powertrain which contains electric swing motor, this study completes a hybrid hydraulic system model. And this model show us a resonable prediction of the dynamic performance of hybrid hydraulic machine.

It is important to develop a model that can characterize dynamic features of transmission in shifting phase to evaluate performance of a controller for an automatic transmission system. And it is very essential to develop a technique that realize dynamic features of clutches that construct a transmission to develop that model. Moreover that model needs to be simulated in real time or semi-real time. But other dynamic analytic simulator software like MSC.ADAMS or AMESim can’t satisfy that feature. So in this research we develop a clutch model that determines stick and slip state of clutches included in a transmission based on fixed step solver.
