基于流体力学仿真的绝缘子空气动力结构多参数优化设计初探

Dianci bileiqi, 2017
为了提高线路绝缘子在重风沙环境下的绝缘性能,最大限度发挥新型空气动力绝缘子的防污特性,基于绝缘子基本结构,提出了4个伞裙结构参数,并针对这些结构参数进行了基于流体场特性的优化设计仿真。4个伞裙结构参数作为优化设计输入参数,上层伞裙下方的矩形截面平均空气流速作为输出参数,分别以上层伞裙2个参数和下层伞裙2个参数各为1个影响因子组合,利用ANSYS Workbench平台进行流体力学计算和响应面优化设计。结合其他设计要求、经验和响应面优化结果,新型空气动力防污绝缘子外形结构的参数建议值可选取 ...

安溪县花岗岩崩岗土体水分特征曲线及其影响因素

Shuitu Baochi Xuebao, 2018
为研究花岗岩崩岗土体水分特征曲线及其影响因素，以福建省安溪县崩岗崩壁土为对象，通过压力膜仪对土体进行脱湿试验，绘制出崩壁土体水分特征曲线，并进行曲线参数与影响因素的相关分析。结果表明：随崩壁土体垂直深度增加，崩岗土体塑性指数、黏粒含量、分形维数及磨圆度等均整体呈降低的趋势；水分特征曲线斜率随着深度的增加而增大，土壤持水能力减弱，残余含水率及VG模型参数a却随之减小，而参数n却随之增大；残余含水率、参数（a、n）均与容重和颗粒的磨圆度呈极显著相关；残余含水率可用容重和黏粒含量描述 ...
