Interference Checking and Verification of Dual-purpose Machine Gun Based on Pro/E

Aiming at the calculation time in interference checking of the general machine gun is too long, a method including three-dimensional entity modeling, virtual assembly, and interference checking of a certain general machine gun in Pro/E environment are designed. Three-dimensional model of each component of the general machine gun are established and the virtual assembly of the general machine gun are completed according to the design drawings. And then, the interference checking function of Pro/E are used to checking the interference of the general machine gun and the interference checking structure are analyzed and the improvement suggestions are proposed. Finally, combined the practical technology, the interference checking results are used in actual assembly and improvement of the general machine gun. The simulation results show that the Pro/E can discover the interference in design, decrease design deficiency, shorten the design cycle, and increase benefit gained effectively.
