Abstract

The present invention discloses a method for evaluating the damage power of a natural fragment-type grenade based on numerical simulation. The method comprises: establishing a calculation model of each power characteristic parameter of the fragmented killing field of the warhead according to explosive damage characteristics of the grenade; and evaluating the damage power of the grenade by using each calculation model. Specifically, a parameter calculation model of the fragmented power field and a parameter calculation model of the shock wave power field are established. According to the methoddisclosed by the present invention, by performing power filed analysis on two main natural fragment-type grenade damage elements of the fragmented power field and the shock wave power field, the purpose of damage evaluation of the natural fragment-type grenade can be achieved; and by using the simulation means for modeling and analysis, not only is the development cycle of ammunition greatly improved, but also the development cost is reduced.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a method for evaluating the damage power of natural fragment grenades based on numerical simulation. Background technique [0002] During the explosion process of the grenade, accompanied by the release of huge energy, two major lethal elements, shock wave and fragments, are produced. As one of the important contents of the research on the damage effect of the grenade warhead, it is very necessary to study and analyze the explosion shock wave and fragments. [0003] However, when the grenade explodes, the process of detonation drive and fragment scattering is a very complicated physical and mechanical process. If the actual test method is used for research, not only the cycle time is long, but also the cost of the test is high. Contents of the invention [0004] The embodiment of the present invention provides a method for evaluating the damage power of natural fragmentati...
