Abstract	The motion of main rotor head of helicopter rotor system is complex. Its reliability influences flying qualities and safety of helicopter directly. But, traditional experiments and deterministic simulation have been difficult to measure movement (flapping, lead-laging and pitching angles) and analyze motion reliability of main rotor head quantitatively. The virtual prototype model was built in the integrating simulation environment, which integrated Catia, MSC. Simdesigner and Adams. On the platform of Adams, we used the deformation of torsional spring to fit the moving angles. The kinematic and dynamic properties were simulated and analyzed deterministically. According to the compared result with the test data, it is shown that the virtual prototype is true and the result is feasible. Finally, we implemented reliability software-ARES which has been developed independently to call Adams and computed the flapping reliability quantitatively. The reliability and the sensitive parameters were obtained. Combined with the results and practical engineering, we presented an effective way to improve the flapping reliability from 0.9904 to 0.9993.
