摘要:
电子设备工作频率的提高,导致电磁辐射噪声日益严重,外壳屏蔽辐射噪声是最为有效的方法. 然而,由于散热和接线,外壳会带有孔洞,极大地影响了其屏蔽效能. 对开孔外壳建模,通过CST仿真得到外壳屏蔽效能的结果,根据仿真结果利用传输线等效电路模型及遗传-进化差分(genetic algorithm-differential evolution,GA-DE)算法进行参数提取,对比屏蔽效能仿真结果和算法结果,证明算法结果的准确性和可靠性,并探究了离开孔面的距离对屏蔽效能的影响,对实际屏蔽设计具有重要意义.
Abstract:
The increase in the operating frequency of electronic equipment has led to increasingly serious electromagnetic radiation noise,and the shielding of the radiation noise by the shell is the most effective method. However,due to heat dissipation and wiring,the shell will have holes,which greatly affects its shielding effectiveness. After modeling the perforated enclosure,this paper obtains the results of the shielding effectiveness of the enclosure through CST simulation. According to the simulation results,the transmission line equivalent circuit model and the genetic algorithm-differential evolution(GA-DE)algorithm are used for parameter extraction,and the shielding effectiveness simulation results and algorithms are compared. As a result,the accuracy and reliability of the algorithm results are proved,and the influence of the distance from the hole surface on the shielding effectiveness is explored,which is of great significance to the actual shielding design.
