Title Twist the system hardware and software design of tube
Abstract This paper is mainly on the diameter of twist for testing 35MM gun tube, the diameter is relatively small, the manual test using the project (manual push rod way) method for twist or lead measurement, using two angle encoder, angle and displacement measurement, to obtain the gun barrel twist or guide pass a calculation method, a set of manual twist measurement system, and the main guide. System includes both hardware and software parts, The paper is responsible for the relevant hardware selection , commissioning and data analysis as well as software based Labview. The hardware includes angle encoder, testing agencies and PXI data acquisition system, Software includes programs written using labview7.1 , signal conditioning , data acquisition , data analysis. Mainly completed the following tasks: through the data acquisition card to shaft angle encoder forward or backward the length of signal and angle signal, send a signal processing circuit for processing, and then sent to the PC host to be processed. The main processing will display the results on the screen: the representation of data and waveform said, can also print output.
