Title The hardware design of a tube straightness test system
Abstract Gun tube is a very important component in an artillery. It is used to determine the initial velocity and firing direction of the projectile. Therefore, fast and accurate measurement of the size paraments in the artillery bore plays a key role in improving accuracy and predicting the remaining life of the artillery accurately.Based on tests of gun tube linearity, this paper introduces a detection system which has adopted the technology of laser collimation and photoelectric inspection to measure gun tube linearity. This system possesses many advantages of high precision, high efficiency, non-touched real-time display and high reliability. It is able to realize quick and exact measurement of internal diameter of artillery tube. It uses PSD as sensors to measure linearity of artillery bore manually. Data collected is transmitted to the IPC through data cables and processed by software platform based on Labview.This paper mainly describes the design of hardware system. By comparing the advantages and disadvantages of various hardwares, appropriate components are selected, assembled and fixed. Finally, data are tested with software. Experiments prove that various indicators of the detection system for linearity have reached the requirements of system design, and the system can meet pragmatic needs.
