Analysis and Optimization of the Blocking Plate in Nuclear Power Plant Based on the Finite Element Method
In order to explore the adaptability of different structures and materials to the operation conditions of nuclear power plant,the finite element models of several types of structures and materials are established.For the finite element model,stress calculation and evaluation and dynamic simulation analysis are carried out.The static method was used to apply normal vertical load to the key parts of the blocking plate to simulate the continuous load.The results show that T700 carbon fiber and ZK60 magnesium alloy can better meet the load requirements of the plugging plate.In terms of structure,hollow and honeycomb structures have better performance under different loading conditions than solid ones.Adopting the 7010 honeycomb aluminum plate,taking into account the optimization of production process and sample experiments,the weight of the blocking plate was reduced from 19.3 kg to 13.2 kg,greatly improving the practicality of the product.
