The optimization of polymer matrix composites manhole lid was done by using ANSYS finite element analysis software.
利用有限元ANSYS分析软件对聚合物复合材料检查井盖进行结构优化设计,阐述了井盖重要参数:盖板厚度、加强筋高度变化对其力学性能的影响,通过数值优化实现了井盖力学性能与井盖用料的平衡,对复合材料井盖设计规范的修正具有一定的参考价值。
The manhole lid is a seal which leads to the top of underground facility, anywhere needs to install the running water, electric power, fuel gas, thermal energy, fire prevention, environmental sanitation and so on the public facility will be installed manholes.
本文研究的聚合物基复合材料检查井盖属于复合材料井盖的一种,由于材料本身属于100%的废弃物,对其它行业而言没有任何回收价值,可以从根本上解决井盖被盗的现象,还可以节约大量铸铁资源,是铸铁井盖的理想替代品。
