摘要/Abstract

摘要： 采用理论推导、仿真分析与试验验证相结合的方式,研究飞机复合材料夹芯板的雷击破损机理和破损状态,为飞机的防雷设计提供依据。通过建立热-电-力耦合物理场复合材料板的三维有限元模型,按结构和作用过程分步进行飞机复合材料雷击效果仿真分析,研究复合材料板遭到雷击后的破损机理以及可能出现的破损状态。通过冲击电流发生器进行模拟雷电试验,观察复合材料板的雷击效果,并与仿真结果相对比,验证了仿真办法的有效性和仿真结果的正确性。

Abstract: Theoretical deducing, simulated lightning test and finite element simulation are used to investigate the mechanism and state of lightning damage of the aircraft composite sandwich panels. It provides the basis for the design of the aircraft lightning protection. The three-dimensional finite element model of the composite board is constructed through the thermal-electrical-mechanical multi-physics coupling field. According to the structure and the role process, the lightning effect of the aircraft composite is analysed to study the damage mechanism and the possible state of the composite plate that is struck by lightning. The impact current generator is used to carry out the simulated lightning test to observe the lightning effect of the composite panel. By comparing the test results and the simulation results, the effectiveness of the simulation approach and the correctness of the simulation results are verified.

Key words: composite materials, finite element, multi-physics coupling field, numerical simulation, simulated lightning test
