In view of the problems, such as lack of experiment link, lack of systematization and weak specialization, existed in the process of teaching and scientific research training for graduate students majored in mechanical engineering at present, with the professional basic theory in the field as the main line and looking on the important equipment in national economic construction and social development simultaneously, the idea and method that to build a synthesized experimental platform which stressed on professional key technology were put forward. The features of comprehensive, multidisciplinary and designing for mechanical subject could be reflected fully in the development process of mechanicalelectrohydraulic synthesized experimental platform and in the illustration of its function features and application examples. It is suitable for conducting seminar learning, casebased heuristic teaching and research activities.
