Title The Development of the Height Automatic Measuring System of the Plastic Sensitive Element
Abstract
Chamber pressure is one of the important parameters which must be measured in firing weapon's design, manufacture and checking. For more than a hundred years, the method of plastic deformation for measuring pressures has been the main means to test the chamber pressure because of its advantages of reliability, convenience and low price. The traditional method of testing the height of the plastic deformation is fussy, and needs expending a lot of manual work, besides, in the traditional testing height the fault is created easily.
Accordingly, the height automatic measuring system of plastic sensitive elements is designed. The system is made up of mechanical structure, height testing system and software and so on. The mechanical structure is used to clamping sensor. The highness after shooting of the plastic sensitive elements is measured by the grating displacement sensor in height testing system. Complete data after the conditioning circuit shaping a square wave, CPLD and microcontroller counts and storage functions. The data reception, date conversions are realized by PC software.
