The levele of simulation are introduced and the importance of virtual prototyping of armament equipment is discussed and steps of virtual prototyping are outlined The faults that affect firing performance are discussed, ADAMS is first to be introduced to armament equipment, and a virtual prototyping model of artillery is established with the help of Fortran language based on analysis of topology of artillery and forces applied on it. The plon of fault evaluation is brought forward, the modules are analyzed, and the concept of fault evaluation function is introduced Finally the perspective of virtual technology is presented The levele of simulation are introduced and the importance of virtual prototyping of armament equipment is discussed and steps of virtual prototyping are outlined The faults that affect firing performance are discussed, ADAMS is first to be introduced to armament equipment, and a virtual prototyping model of artillery is established with the help of Fortran language based on analysis of topology of artillery and forces applied on it.
