The experiments of vibration reaming small caliber gun tube with cemented carbide reamer are carried out.

The vibration reaming experiments of a small caliber gun tube were carried out by the auto aligning reamer.

Total transfer matrix and vibration frequency equation of gun tube were deduced.

To test the inner surface of the artillery pipe, a new algorithm of image registration algorithm based on phase-correlation is proposed.

This paper takes advantage of the features of the inner surface image points in artillery pipe,and proposes an algorithm based on small number of feature points on inner surface of artillery pipe.

Aimed at some problems that radial wear quantity measuring accuracy of gun barrel inner bore was low,and the degree of automation was not high,by use of laser un-touched measuring technology,a precision measuring system of gun barrel inner diameter was designed.

The purpose of this thesis is to design a measurement system of the inner surface roughness and a defect recognition system of the inner surface based on the digital image processing technology, which are parts of the on-line nondestructive examination (NDE) of the inner surface quality of the gun barrel.

A new kind of strength design method of gun barrel and corresponding safety coefficient choice range were presented,and the strength failure process of gun barrels was analyzed.

It is a gradual retrogressive process in the use of a gun barrel from being brand new to being finally discarded as useless.

Reqarding problems of current examination methods of barrel linearity, this paper, introduced the principle and methods to examine the barrel linearity with CCD, collimator and computer.

For measuring inside diameter of barrel, it is put forward that a project on grating instrument with small range that combining grating sensor with data processing technology, with which automatically detection and assessment with inside diameter of barrel which can be true in this paper.
