Research In Microvibration Simulation Of The Building Structure Based On OpenGL

While the development of China's cities and the prosperity of the traffic,the structure's microvibration is focused more than before.Structure microvibration with randomness of environment vibration,and the structure will have a complex response under such environment vibration,then make a damage to building.Therefore,the anti-microvibration of structure design is a important issue to be considered,especially for building design near urban transport road,such as the high-tech plant.It's necessary to study the performance of structure anti-microvibration and rise rational prevention program to control the microvibration of structure.At present,the study of anti-microvibration more focused on equipment,vibration reduction measures and power analysis.But the visual simulation of structure anti-microvibration is less mentioned.The use of visual simulation can transfer planty of data into three-dimensional dynamic display of graphical images,can help designer to design and analyse the structure,can choose the reasonable structure arrangement quickly, have great significance in structure anti-microvibration design.At the same time,the visual simulation of anti-microvibration is also associated with plant operations manager of a factory building designer ties to optimize plant operations.This paper bases on WINDOWS operation platform,using MFC of VC++ and OpenGL language to join,validate the above theory,come true the digital visualization simulation,form a simple and easily operational visualization simulation software,this software has the function of hereinafter several aspect:(1)Make the high-tech plant's size and attribute parametric.Define global variables for plant's size and attribute to make human-computer interaction simulation system.(2)The view of structure microvibration analysis.According to Delaunay triangle-net and grid of scattered points,reflect the deformation of structural members,Regulate light and structure material by OpenGL.(3)Creating APDL orders for ANSYS microvibration analysis under human-computer interaction by given parameter of plant's size and Finite element's size.(4) Picture transform operation.These operations can translate,rotate and scale the builded pictures. (5) Inquiration function.It can inquire earthwork quantity,road transect,vertical section, and check the actual effect of the joint of road and terrain by transform operation.This paper empolders the building microvibration simulation system,which is object oriented and exoteric,has the friendly operation interface,operates easily,conveniently and fast etc.
