Simulation Study Of Discrete Rod Flying

In this dissertation, on the basis of theoretical analysis and simulation research, explosive drive and moving law of rod about controllable discrete rod warhead of center initiation is researched preliminarily.In theoretical research, physical model and calculating model of rod velocity about discrete rod warhead is established, and basing on this, the moving equation of rod center is analyzed. It is the illuminated the effect of parameters of warhead on the moving state and damage efficiency of the discrete rod by program operating. Physical and mathematics model of rotate speed about discrete rod is established, and provided the research method of rotary mechanism about the rod through analyze and calculate, discussed the effect of install angle on the performance about flying rod, provide theoretical thereunder for discrete rod warhead of structure and power parameters design.General differential equation of flying law about discrete rod is established, point out the general law about rigid body roll stator. Euler angle conception is introduced and the movement equation of discrete rod is predigested by the relationship between the Euler angle and direction cosine . Analyse moving law of flying rod by numerical method, which provided theoretical basis for general analyse about moving law of flying discret rod to a certain extent. The theoretical analysis is proved to be true by comparing the conclusion of experimentation and theory.The achievements of this dissertation have use for reference and practical consulting value for researching personnel who major in controllable discrete rod warhead.
