一种精确打击下桥梁毁伤视景仿真系统设计实现

Design and Implementation of a Bridge Damage Simulation System under Precision Strike

目前,在桥梁毁伤仿真领域采用的数值仿真方法虽具有精确性高的优点,但是仿真过程不直观、形象,整体性不强。采用视景仿真技术进行精确打击下桥梁毁伤仿真,在保证精确性要求的基础上,利用Unity3D软件以三维画面的形式进行展示,仿真过程形象、直观、明了。给出的精确打击下桥梁毁伤视景仿真系统的设计方法,能够满足真实性和实时性的要求,利用Unity3D自带的物理引擎完成了桥梁模型的物理特性建模和爆炸仿真分析,通过全过程仿真,能够分析得出相应的毁伤结论,达到了预期效果。

Presently,the numeric simulation method of the bridge damage under precision strikehas high accuracy,but nether visual nor vivid,integrity is not strong. By using the Unity3D software,thebridge damage simulation under precision strike by scene simulation technology provided by this papermeets the accuracy requirement;moreover,it visualized the simulation process with 3D effect. Thedesign method given by this paper also meets the requirements for real -time performance andauthenticity. The design of physical characteristics and the corresponding analysis of the explorationeffect of the bridge model is finished by using the physical engine of the Unity3D software,throughsimulation and analysis of the whole procession,the damage conclusion of the bridge can be get,theexpected effect is also get.
