The fault simulation and forecast technology based on virtual prototype for artillery is put forward to realize predictive maintenance and improve task accomplishing capabilities. The fault forecast technology for artillery is to take the artillery＇s current service state as the start point and forecast the possible faults in future tasks. The virtual prototype for artillery is established, which is adopted into fault forecast field as a new kind of quantitative reasoning method. A new forecast reasoning mechanism based on dynamic fuzzy comprehensive evaluation is put forward. The fault simulation process based on virtual prototype infirms the actual faults and finds out the corresponding fault causations and components, which is the foundation of proactive maintenance.
