In order to repair the flaws of traditional design method,it is reasonable to introduce the Monte Carlo method to the reliability design and analysis of gun components.

Bending deformation and bending rigidity of mechanical components;

On line detection technique for linear strain of mechanical components based on magnetic lattice;

Combined with the implementation of fuzzy mathematics and failure diagnose in failure diagnose of mechanical component, this paper studies the role and effect of fatigue failure tree and failure diagnose model from the viewpoint of failure analysis.

Velocity measurement equipment of underwater gun s automatic machinims;

The center of mass of gun is one of the most important parameter in the testing of gun,the offset between the center of mass of gun and the axes of bore will affect the precision of fire.

Principles of product data management require that bills of materials be formed in the department of gun design.

Cleaning and cooling occasions of firearms are the important indexes affecting their firing lifetime.

In order to investigate the rationality of firearm shooting methods instituted under military standards,shooting methods of all kinds of firearms satisfying the needs of tests and practices of actual battles were proposed on the basis of actual battle analysis and research.

When the motion of a firearms mechanism is known, graph theory can be applied to describe the features in such a multibody structure.

By choosing the right methods to establish guns′reliability model,and based on analyzing the characters of guns′ reliability experiment,the corresponding hypothesis is put forward.

The environmental test and it s management at home and abroad were introduced, and the concept of Environmental engineering was recommended to apply when design and manufacture guns to improve the environmental worthiness of guns and manufacture our famous guns in the world.
