Abstract: To solve the operation efficiency problem in High Level Architecture(HLA) distributed interactive simulation，desktop grid simulation platform was designed and realized. Through the application of desktop grid technology into distributed interactive simulation area，effect of desktop grid on distributed interactive simulation was studied, and desktop grid simulation architecture was designed. In this platform，management flow and operation flow of simulation grid were put forward. A kind of load balance algorithm based on comprehensive evaluation of computer load using multiple factors was established. The platform solved the problems of resource management and model load balance issues in distributed interactive simulation. The application of aircraft simulation verified the feasibility and effectiveness.
