Title Diameter of large caliber artillery tube based on virtual instrument measurement technology
Abstract
Barrel is the key part of the artillery, and its function is to give scheduled shooting direction and initial velocity of the projectile, to enable artillery combat missions completed. Therefore, rapid and accurate measurement of the cannon bore size parameters has a key role to improve firing accuracy and prediction of gun tube life.
This paper presents a new type system of high precision diameter of artillery tube inspection, to achieve accurate and rapid measurement on the inner diameter of the gun. it Introduced test system hardware, software design, how it works, test methods, analyzed the test procedure. The system adopts inductance type displacement sensor and laser ranging sensors as the sensing element, enabling the measurement of the diameter of artillery tube. And for the entire test system requirements, we used the virtual instruments, under the support of the software, we can measure accurately the Barrel diameter size changes of any arbitrary cross-section, and can achieve rapid real-time data processing and display output. At last, this paper analyzed the interference and causes of the error, and made some corresponding measures to reduce error.
