摘要:
近年来,经济的高速发展使人们寻求更快捷的出行方式和运输方式,飞机的方便快捷使其被大力发展,其安全问题也被人们关注并提上研究日程。基于SPH的方法,使用ANSYS/LS-DYNA软件建立了鸟撞层合板的仿真模型,通过仿真分析了鸟撞的四个阶段,首先研究了临界速度前鸟体初始速度与层合板的接触力及鸟体损伤能量的变化情况,然后对比了鸟体损失能量与鸟体质量的关系。结果表明当冲击速度小于临界速度时,接触力峰值随鸟体速度的增大而增加,速度的变化与鸟体损失能量之间呈抛物线关系。
Abstract:
In recent years, the rapid development of the economy has led people to seek faster modes of travel and transportation.The convenience and speed of the aircraft have been greatly developed, and its safety issues have also been paid attention to and put on the research agenda. Based on the SPH method, the simulation model of the bird impact laminate was established using ANSYS/LS-DYNA software.Through simulation, the four stages of bird collision are analyzed. Firstly, the relationship between the initial velocity of the bird body and the contact force of the laminate and the damage energy of the bird body before the critical velocity is studied. Then the relationship between the loss energy of the bird body and the bird mass is compared. The results show that when the impact velocity is less than the critical speed, the peak contact force increases with the increase of the bird’s body velocity.There is a parabolic relationship between the change in speed and the energy lost by the bird.
