建筑信息模型(BIM)技术在AP1000核岛大件吊装仿真中的应用

全球首批三代核电AP1000核岛采用模块化施工技术,可产生巨大的经济效益,大件吊装技术是其关键技术之一。针对AP1000核岛的吊装施工过程存在的吊装方案制订、吊装过程动态模拟、吊装过程吊件等结构分析、以及吊装运输碰撞检测等多重问题,指出运用建筑信息模型(BIM)技术实现大件吊装仿真的必要性。在简要介绍BIM技术的基础上,提出基于BIM技术的吊装施工动画仿真模拟平台;给出了吊车的BIM模型的定义方法;并介绍了利用BIM模型来进行基于3DS Max软件的三维动画模拟和基于ANSYS有限元软件对吊件等进行结构分析的方法。

APPLICATION OF BIM IN SIMULATION OF IMPORTANT LOAD LIFTING FOR AP1000 NUCLEAR PLANT

Modular construction is used for AP1000 nuclear island of the third generation of nuclear power station,which provides great economic benefit.The important load lifting becomes one of the key techniques.The necessity of the important load lifting simulation based on BIM technique is pointed out,which is for the problems exist during the AP1000 nuclear island lifting,such as lifting planning,lifting animation and simulation and collision detection.The BIM-based lifting animation and simulation platform is put forward after the brief introduction of BIM.The definition method of the crane BIM model is shown.And the way to simulate with the BIM model based on 3DS Max software and do structural analysis based on ANSYS software is introduced.
