Study On Computer Simulation Analysis System Of Shell In Internal Ballistic Test

Sincerely years, the parameters of inner ballistic trajectory of shells are very important when research and develop shells, finalizing the design; manufacture finalizing the design and quality control in batch for the shells. The conventional experimentation method as follow: use copper pole measure method and electricity measure method to test the pressure of chamber of big gun; use electron measure time apparatus and the start-end equipment to test the original velocity. It is greatly restricted for design and study of shells. If take the manifold parameters, such as: p-t, v-t, a-t, p-l, n-t, n-l, the relations between the parameters and graphs into the data simulation system of the computer, in others word, the technicians obtain the parameters directly of inner ballistic trajectory in different schemes from the computer system when research and development the shells, compare and select the excellent schemes. The principle of computer simulation analysis system of shell in internal ballistic is to use applied mathematics methods, such as: Lap lace equation, Green function, Fourier series, and Euler arithmetic, base on conventional inner ballistic and modernized inner ballistic models to renew mathematics and physics models, recycle software developing tools to code. Input the performance parameters of pill and powder into the computer, calculated and analyzed by the software simulation system, study profundity the performance of inner ballistic, reduce enormously the times of experiment, depress the cost of scientificresearch, speedup the course of shell development, improve the quality of shell design. This article expatiates and argumentations contents as follow: background and meaningof study the task, basis concept of system simulation, technology of seeable, the theory of inner trajectory and test data analysis, inner trajectory numerical value simulation and test result analysis, computer simulation analysis system of shell in internal ballistic test, technology exploitation scheme of 3D simulation software and so on.The precision and reality of the simulation analysis system is decided by the legitimacy of inner trajectory mathematics and physics models built. The thesis references books about shell inner trajectory, sum up the mathematics and physics models about the sutra inner trajectory and modern inner trajectory, according to a great deal of inner trajectory test data of our manufactory in past years, utilize software of MATLAB, use curve imitate method, set up mathematics models.In order to make the integer truss software of simulation analysis system in reason and ability, the thesis reference a lot of books about system simulation technology, consult experts and professors engage in software exploitation and design for many years, establish collectivity design idea of software truss of the simulation analysis system, that is to say, for realize real time 3D simulation of inner trajectory result, obtain better simulation effect of 3D, realize real time control of 3D, output curve, use 3DSMAX to model, carry out veracity of models and impact of 3D images, use Visual Studio as software exploitation flat roof, transfer OpenGL, code in Visual C++, transplant models of 3DSMAX into the programmed circumstance of Visual C++, use programmed to control moving pictures create, courses and real time trajectory data connect and draw curve. Select technology scheme not only to display real time parameters and curve of pill, but also make the movement gesture of pill reality.On account of the thesis deal with subjects abroad, accomplish the thesis finally, need enough time, material resources, scientific research outlay, many specialty technology person with ability who engage in software exploitation and trajectory research, I put forward the collectivity design idea of the thesis, conclude the mathematics and physics models, carry out portion works of the thesis, the rest works complete in the future.
