摘要
使用有限元软件ANSYS建立某核电厂反应堆厂房内部结构三维模型,并根据工艺条件图所示的设备、管道支承位置施加单位荷载以计算相应柔度矩阵,为主设备、管道在反应堆冷却剂失水事故(LOCA)和地震工况下的计算提供基本参数。
This paper uses ANSYS( Finite Element Software) to create a three-dimensional model of the internal structure of the reactor of a nuclear power plant and then,based on the technical requirements,unit load is applied to calculate relevant flexibility matrix of equipments and pipelines. The result of the calculation is the fundamental basis for the analysis of the equipments and pipeline connections under earthquake and LOCA( lost of coolant accident).
