摘要
研制的磁力提升装置实现了对加速器驱动次临界系统(ADS)新型钨基合金球靶材的电磁提升.其基本原理是通过控制一组螺线管的加电时序,实现磁场的移动,移动磁场作用于靶材完成其输运.螺线管作为该装置的主要部件,其结构影响电磁提升的效率.为优化其结构,采用Ansys Maxwell分析螺线管的磁场分布,确定螺线管结构.同时利用Ansys Maxwell给每个螺线管加不同宽度的脉冲进行数值模拟,通过调节每个螺线管的通断电时间和同时工作的螺线管单元数,模拟计算合金球的受力.在数值模拟的基础上完成了磁力提升装置样机的加工和实验研究,实现了钨基合金球输运的预期效果.
Abstract
The lifting device prototype is developed to realize the transportation of tungsten alloy balls.The tungsten alloy balls are new targets used in the accelerator driven subcritical system(ADS).The basic principle is the electromagnetic force of the solenoid.Controlling the power-on and power-off time of a group of solenoids can achieve the movement of magnetic field.The magnetic field acts on the targets to complete the transportation of alloy balls.The solenoid is the main component of the device and its structure should be beneficial to lifting the targets.Ansys Maxwell is used to analyze the distribution of magnetic field for solenoid to determine the structure of the solenoid.It is also used to accomplish simulation at different pulse width for each solenoid.Power-on time and power-off time of each solenoid and the number of solenoids working simultaneously are regulated to simulate the force of alloy ball.Based on the numerical analysis,the processing and experiments of the device prototype have been finished.The results show the device prototype has achieved the desired effect of tungsten slloy ball transportation.
