Explosive Welding Research And Development Of Computer-aided Design System Ewcad1.0

In this paper, author introduced how to research and exploit software of Explosive Welding Computer Aided Design. By which more further research on theories of explosive welding and optimized technological parameter of explosive welding. EWCAD 1. 0 system mainly include some model just as follow: (1). One dimension answer will be calculated under condition of explosive load. Making use of one dimension GURNEY formula, AZIZ formula and DERIBAS formula calculate the last value of velocity which is movement of flying plate. More over result of calculation was save respectively data bank. (2). Calculating two dimension numerical solution about movement of fly plate and simulating flying attitude of fly plate in the space. Moving Attitude curve of fly plate will be given by algorithm of Richter and characteristic curve method, Accelerated process of fly plate that was acted by explosive wave was described quantitatively. (3). Defining window of explosive welding. EWCAD 1.0 system can define window of explosive welding in the theory. Correlation parameter will be corrected by experiment mode. Further more deriving actual window of explosive welding and calibrating the best field of welding. (4). In the data bank resource manage modal, building data bank of explosive composite material and of output result by software calculating, by which realized common data bank manage function that is viewing data, repairing data, outputting report forms and printing data. (5). Encrypted data: for the sake of preventing use the software illegally by other people. Applying two level password to encrypt EWCAD 1. 0 system. According to respectively user type, EWCAD 1. 0 system will put forward correlated using limit.
