Design And Development On Virtual Simulation System Of The Small-Scale Experiment Apparatus Of Tectonic Distortion

Tectonic distortion and hydrocarbons-infusing simulation experiment is a key method ofstudying tectonic characteristics, formation， evolution mechanism and hydrocarbonmigration，accumulation process, which is also a significant guidance of oil and gasresources exploration. This research is to design a set of small-scale experimental apparatusfor tectonic distortion based on the original tectonic deformation experimental equipment anddevelop a3D virtual simulation system with the function of human-computer interactionaccording to fault seal ability, tectonic geology and similarity theory.The small-scale experimental apparatus decreases the size of the geological model andhas the characteristics of compact structure, which realizes mechatronics integration andexperimental process integration. The small-scale experimental apparatus reduces theconsumption of the resources and avoids the geological model being damaged in the processof secondary carrying. This design will improve the success rate of experiments and ensurethe effectiveness.At present there are some deficiencies in the tectonic distortion experiment, longexperiment period，many intervened phenomena between mechanical devices，affected byuncontrollable factors. To improve the experiment efficiency and establish a laboratorialteaching-training platform，a virtual simulation system with features of interactivity，authenticity，usability and security is to be developed using Virtools, which is composed ofthree parts of model-making, installing of deformation devices and stress loading according tothe tectonic distortion experiment process. The key technology of virtual simulation systeminvolved several points: role control, virtual assembly, collision detection, etc. The users canexperience the virtual tectonic distortion experiment in scenario interfaces. Utilizing the parameterized modeling technology, the initial3D model of the small-scale experimentapparatus for tectonic distortion is to be built and then imported to Virtools after beingoptimized in3D Max, which will ensure the authenticity of the virtual simulation system. Theviewpoint module will provide an omnidirectional and controllable perspective in3Denvironment. Meanwhile the database and communication module which can record theexperimental information is to create a connection between the virtual simulation system andthe external database Access. Test results showed the virtual simulation system is fullyfunctional and strong practical; it meets the design requirements and will offer a newtechnological method of the tectonic distortion experiment for an in-depth study.
