UMS for miscellaneous airborne electromechanical devices is the part and parcel of VMS. The object of utility management is airborne electromechanical devices which ensure that air engine, avionics and other systems work in order. This paper works over several items about UMS by introducing advanced simulation and its correlative technologies. Firstly, message transmission software of 1553B bus is designed and the bus characteristics are tested. Also, the problem of time synchronization is solved by testing network delay. Secondly, in order to obtain high performance of distributed process ability, heuristic job dispatching algorithm and hydrodynamic load balancing strategy are adopted, which solve the static job dispatch and dynamic job scheduling respectively. The hydrodynamic load balancing strategy is aiming to fulfill the resources usage in the whole system and accomplishes best resources sharing. Thirdly, this paper establishes and realizes the demo environment for visual simulation of the electromechanical subsystems. Adopting tree-mode during the software design makes the system scalable and reconstruction. As multithreading synchronization is resolved, real-time performance of simulation. is ensured during.
