AbstractTraining systems based on simulation technology proved the effectiveness compared to the real systems. This paper introduces the design of a fullmission BMP1 simulator. This simulator includes mathematically realtime dynamics, 3D display, sound effect, 3-DOF motion platform and self evaluations. The simulator is designed compatibly to low cost hardware devices. The 3-DOF motion platform uses 3-phase AC motors controled by inverters. It satisfies highly response rate and energy saving. Evaluation systems help instructors observe the training results and automatically score. The simulator satisfies training requirements.
