However, the models ’ reusability often f ailtoa chieve anticipate. An o bject o riented classified method is put forward, which classifies different functional sub-models into categories, and orders them regularly ponent library. All these works are based on the AMESim programming environment. ponent library has the characteristics of expansibility , practical applicability and reusability. It’s convenient to model hydro-mechanical units for a new type of aero-engine . The library also can work with MATLAB , LABVIEW and other softwares easily for co-simulation a nd real-time simulation. It’s easy to re use the ponents and statistics and the library is conducive to the development of hydro-
