Numerical Analysis of Electromagneto-Mechanical Coupling Dynamic Response of a Typical Tokomak Structure

In an effort to simulate the dynamic behavior of a non-ferromagnetic conducting structure with consideration of the magnetic damping effect,a finite element code is developed,which is based on the reduced vector potential (Ar) method,the step-by-step integration algorithm and a time-partitioned strategy.An additional term is introduced to the conventional governing equations of eddy current problems to take into account the velocity-induced electric field corresponding to the magnetic damping effect.The TEAM-16 benchmark problem is simulated using the proposed method in conjunction with the commercial code ANSYS.The simulation results indicate that the proposed method has better simulation accuracy,especially in the presence of a high-intensity external magnetic field.     

建立健全能耗限额标准体系 实现经济效益目标

重点企业能耗数据调查对标工作探讨

一、能耗数据调查对标工作基本情况在自治区质监局计量处的安排下,我院能源中心结合自治区发改委批准立项＂重点耗能企业能源计量数据采集管理信息平台建设项目＂（以下简称＂数据平台＂）的思路和自治区发改委能源统计信息的要求,在2011年调查汇总分析工作的基础上,编制了《新疆重点耗能工业企业2011年能源消费情况调查表》,引进了＂重点耗能企业能源计量数据网上直报系统＂,包括企业基本信息、主要能源（耗能工质）消耗情况、产值、增加值能耗情况、主要产品能耗情况、能源计量器具配备和管理等内容。     

考虑电磁机械耦合效应的电磁超声数值模拟方法

提出了考虑速度效应电磁机械耦合的电磁超声数值模拟方法,并开发了相应的程序。该方法在控制方程中导入了速度诱发电场项,并采用退化向量位法(Ar)进行涡流场数值模拟和采用有限元及逐步积分方法进行超声波计算。数值模拟所得EMAT信号和超声波传播过程均证实了本方法和程序的有效性。为了确定耦合效应的影响,对考虑耦合和忽略耦合两种情况分别在不同条件下进行了数值模拟。通过比较振动幅值和洛伦兹力的模拟结果,证实耦合效应对EMAT数值模拟结果影响并不显著。     

Numerical Analysis on the Magneto-Elastic Stability of Current-Carrying Conductors: Aiming at Applications for the Tokamak System

A novel method for calculating the magnetic stiffness matrix was proposed for the numerical analysis of the magneto-elastic stability of complicated current-carrying structures aim- ing for application in the magneto-elastic behavior of the tokamak system. A code based on the proposed method was developed and applied to the numerical analysis of two typical current- carrying structures. The good consistency of the numerical and analytical results validated the proposed method and the related numerical code.
