Research On Blasting Engineering Learning System Based On Virtual Reality Technology

Controlled blasting technology has been applied more and more widely indemolition of the urban tall buildings in recent years. Because blasting demolition isa highly dangerous work, it can not allow any mistakes during the blastingparameters selection and program design for blasting staff, otherwise theconsequences could be disastrous; and it is particularly important for simulation andevaluation of the effect of blasting demolition of the blasting demolition programand blasting technology training for blasting staff. Because of destructiveness anddangerousness of blasting demolition, it is difficult to provide an effective practicaltraining environment for blasting learners, this paper researches the constructionmethods and techniques of blasting demolition learning system based on virtualreality technology, achieves fast construction of blasting demolition building objectsand environment, the interactive design of blasting demolition program andthree-dimensional simulation of the collapse of the housing process, effectivesupports the design of project of blasting demolition and the effect of simulation ofbuildings, at the same time, the system can be used as a new learning platform forlearner about the blasting demolition technology.In order to construct the three-dimensional model of the buildings quickly andeasily, this paper based on component and parameterized drawing technologies,researches the three-dimensional modeling software MultiGen Creator’s componentplug-in for construction the buildings based on OpenFlight API, achieves thethree-dimensional geometric modeling and the set of physical properties ofcomponent, formed a basic component library for users when constructing athree-dimensional modeling of building. After analysis and comparison, this paperchooses the demolition blasting control theory model that has been widely used andeasy to calculate to establish blasting demolition of kinetic control model, laying thebasis of the theoretical model for the design of project of blasting demolition and theeffect of simulation of blasting demolition. Researches the interactive and visual design technology of the project of blasting demolition and the three-dimensionalvisualization technology of blasting demolition process based on Vega, designs thecorresponding experimental system using the Vega and the VC++6.0,achieveseffective supporting the interactive and visual design of the project of blastingdemolition and simulation of the effect of blasting demolition.
