| AutoCAD is an Engineering aided design software, it integrates the advantages ofwide coverage for users, engineers’ skilled application, easy to three-dimensionalspace description and two-dimensional space conversion, etc. The thesis studied themodeling problems of AutoCAD-based RCC pouring simulation system base on theanalysis of the problems exist in RCC pouring simulation system. A simulationplatform has also been developed with Visual Basic and ActiveX technology. Thisplatform embeds the RCC pouring simulation into AutoCAD system, and makes thedesigners who are familiar with AutoCAD can build simulation models and analyzesimulation results easily. This platform also improves efficiency of buildingsimulation models and the visualization level in this period. In order to achieve thesegoals, the thesis conducted the following aspects of work:(1)By studying secondary development of AutoCAD national andinternationally especially the application results of CAD and simulation modeling,and combining the basic features of RCC dam construction, we can create a methodthat integrated RCC dam construction simulation and AutoCAD modeling.(2)By the secondary development of AutoCAD and the utilization of functionalmodule in AutoCAD, we can organize a3D dam model which include projectinformation and achieve3D display on the pouring scopes of machine in the system.These make people know the accuracy of the model more visually.(3) According to the mechanism of the system simulation stated in this thesis andthe principle of simulation, process of RCC dam construction simulation can bestudied and realization the dynamical visualization of calculation process ofsimulation in AutoCAD can be achieved.(4) Achieving the information inquiry of arbitary RCC dam block as well asmonthly pouring face and verifying the above functions of the simulation system bystudying a project example. |
