Abstract

The embodiment of the invention provides a damage effect evaluation method and device of an explosion shock wave. The method comprises obtaining the environmental model parameters and the mannequin model parameters, obtaining explosive category, explosive name and explosive mass, calculating TNT equivalent corresponding to explosive according to explosive category, explosive name and explosive mass, and obtaining explosive radius according to TNT equivalent corresponding to explosive; inputting the environmental model parameters and the mannequin model parameters, as well as the radius of theexplosive into the K file of ANSYS/LS-DYNA software to obtain the target calculation file; and then calling the ANSYS/LS-DYNA software to calculate the target calculation file based on the total timelength and the core number of ANSYS/LS-DYNA, and evaluate the damage grades of various parts of the human body according to the calculation results. The method and the device can automatically createand obtain different explosion environments according to parameterized settings, and are used for simulating human body damage under different explosion environments, and can directly, accurately andefficiently evaluate human body damage caused by explosion shock waves.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of finite element numerical simulation, and more specifically, to a method and device for evaluating the damage effect of an explosion shock wave. Background technique [0002] The damage to the human body caused by the blast shock wave is mainly determined by the overpressure of the shock wave and the action time of the shock wave. When the explosion shock wave interacts with the biological tissues of the human body, it will induce stress waves in the biological tissues of the human body. During the propagation of the stress waves in the biological tissues, it may cause mechanical phenomena such as rupture, tearing, and implosion of the biological tissues, thereby affecting the biological tissues. produce a traumatic effect. The damage to the human body by the blast shock wave is mainly concentrated in the biological organs containing air, such as the eardrum, lung, stomach, etc., and...
