With the rapid development of the construction industry , the growing number of high-rise buildings , the tower crane ( tower crane for short ) its rotary arm length , lightweight structure , installation , dismantling , as well as convenient transportation , the construction industry indispensable mechanical . However , the growing demand for tower crane and its relatively weak the incompatible training work , leading to the tower crane accident -prone . The tower crane workers belong to special operations personnel must undergo a rigorous training certificates after passing the examination . The traditional training methods training cycle is longer , serious waste of resources and poor security, training is not in place , to the safe production of potential problems . Application of virtual reality technology developed tower crane simulation training system of economic , security , efficient and independent of time , climate , site constraints , either specification operator behavior can improve enterprise efficiency , and has broad application prospects . Firstly a brief introduction of virtual reality technology to analyze the characteristics of the simulation training systems based on virtual reality technology to achieve the requirements as well as the key technology , in order to determine the system integration platform based VC.NET create software 3DS MAX system geometry , Virtools software model-driven development program . Then , based on the tower crane training , the assessment of the actual needs of the system functional design , architecture design . Optimize the order in accordance with the three-dimensional solid modeling , motion simulation modeling , physical simulation modeling , simulation effect , the completion of the research and design and development of the tower machine simulation training system . In the system development process , take the modular development approach , the entire system in accordance with the functions into the basic movement module , physical simulation module , evaluation modules , scene effects module subsystem . Among them , the use of virtual reality platform Virtools motion simulation modeling and physical simulation modeling is the focus of this article . The motion simulation modeling lies in the actual law of motion of the moving parts in the the analog tower crane operation to improve the authenticity of the system ; physics simulation modeling using Virtools Physics Pack establishment of hanging objects deflection model , using virtual prototyping and analysis software ADAMS analysis , validation of the model , in order to better achieve the hanging objects yaw of the tower crane movement process simulation .
