摘要
在电磁场应用问题的研究中为了解决电磁场产生装置在工作点的漏磁感应强度不足,磁感应强度不稳定及其在指定路径上的分布等问题,为了满足磁感应强度稳定性要求,提出了电磁场产生装置的优化仿真设计方法,建立了电磁场计算的数学模型,并采用有限元方法对电磁场产生装置进行计算。建立了以工作点的磁感应强度为目标函数的优化模型,得到磁极气隙宽度的优化值。采用闭环控制系统实时调整线圈供电电流进而保证工作点磁感应强度满足误差要求。经试验测试,并将试验结果与仿真分析结果进行比较分析,试验结果与仿真分析一致,验证了仿真、优化及控制方法的可行性和实用性。
In order to solve the lack of leakage magnetic induction on the working point,the instability and the distribution on appointed path of magnetic induction of electromagnetic field generator,this paper puts forward design method of optimization and simulation on electromagnetic field generator,and builds mathematical model of calculating electromagnetic field,and calculates on electromagnetic field generator by finite element method.Optimization model of objective function is built based on magnetic induction on the working point,and optimized values of the width of gap of magnetic pole is obtained.In order to achieve the stability of magnetic induction,a closed loop control system is put forward so that the magnet induction error meets the requirements on the working point by controlling the current of the loop.The test results and simulated results are compared and analyzed,which are consistent.The feasibility and the practicality of the simulation,optimization and control method are verified.
