This paper analyses the functional relations of mechanical engineering system and establishes technical system state variables. By elementary components of bond graph we determine state space transforming matrix and build the technical system state space model according to energy transmit in mechanical engineering system. Multi-solutions are produced with the aid of state space transforming operations. A simple design verification case of an electric intravenous infuser is presented to show an application.
