Relative Sensitivity Analysis of Typical Faults of Guns Based on Virtual Prototyping Technology

As conventional land-based armament, guns are playing an important role in local wars in recent decades. The typical faults of guns are analyzed, and three indexes to represent guns performance are put forward and three working principles of guns are outlined. Virtual prototyping model of some-type gun is created by using ADAMS, and the validation is suggested by comparisons of simulation and test results. The degrees of guns faults affecting performance indexes are obtained based on relative sensitivity analysis, thus the comparison difficulty of fault parameters with different dimensions is solved, and the parametric thresholds of guns faults are achieved through virtual prototype according to firing limits of guns. Finally, the perspective of virtual prototyping technology applied in fields of armament engineering is presented.
