AI Technical Summary

Technical Problem

Existing live-fire detonation experiments in teaching suffer from high risks, high costs, difficulty in replication, and difficulty in observation.

Method used

A virtual simulation system for sympathetic detonation experiments with charged explosives is provided, including a sympathetic detonation model construction module, an experimental interaction module, and a sympathetic detonation implementation module. The system uses Unreal Engine to render virtual main explosive, virtual charged explosive, virtual bottom witness target, and virtual protective structure. The deformation diameter of the bottom witness target is calculated by fitting a formula through dimensional analysis, and the sympathetic detonation process is simulated in the virtual environment.

Benefits of technology

It enables safe and low-cost repetition of sympathetic detonation experiments in the teaching system, visually demonstrating the sympathetic detonation process and damage, overcoming the risks and observation difficulties of live-fire experiments, and supporting differentiated simulation of protective structures.

Abstract

The present application relates to a kind of virtual simulation system for the sympathetic detonation experiment of shell charge, belong to sympathetic detonation simulation technical field, solve the problem that the risk of high, high cost, difficult to repeat and difficult to observe in the teaching of existing technology in live sympathetic detonation experiment.There is a sympathetic detonation model construction module for constructing the three-dimensional basic model of main charge, charged charge, bottom witness target and protective structure, and then rendering virtual main charge, virtual charged charge, virtual bottom witness target and virtual protective structure in unreal engine;Experimental interaction module is used to set control data and generate control command and send to sympathetic detonation implementation module;Sympathetic detonation implementation module is used to set the sympathetic detonation model construction module according to the control data received, simulate the sympathetic detonation process in unreal engine, also used to control the sympathetic detonation process according to the control command received.The sympathetic detonation experiment of shell charge is virtually simulated.
