Gaoya dianqi, 2015 特高压线路棒形悬式复合绝缘子表面电位分布极不均匀,绝缘子高压端金具附近绝缘子护套表面局部电场强度很大,加速了绝缘子的老化。工程上通常用安装均压环的方法来解决该问题。均压环结构参数决定了其均压效果,为得到较优的均压环参数,需要对其管径、环径、罩入深度的优化设计进行研究。由于复合绝缘子的结构特点使得单元数量较多,求解耗时长,常规遗传算法应用于该课题具有优化过程耗时较长的问题,因此使用改进的优化算法对均压环参数进行优化。改进的RBF-GA混合算法综合了RBF神经网络任意函数逼近能力和GA算法的全局优化能力 ...

Jianzhu Gangjiegou Jinzhan, 2011 本文采用Matlab语言编制了张弦桁架结构通用的有限元模型分析程序。通过此程序,可以快捷地得到不同几何参数的张弦桁架结构模型,并能进行杆件内力分析,分别采用SAP2000和ANSYS分析软件对其计算结果进行了验证,结果表明三者的计算结果一致。在此基础上,采用Matlab语言编制了粒子群算法优化程序,对某实际张弦桁架结构采用本文优化方法进行了优化设计,优化结果表明本文提出的优化方法具有较高的精度和较好的收敛性。最后对不同跨度的张弦桁架结构模型进行了截面优化设计,为初步设计提供了参考。
