商用飞机撞击刚性墙的荷载时程分析方法
|
摘要
针对商用飞机撞击刚性墙问题开展研究。首先,使用ANSYS/LS-DYNA软件建立了飞机的有限元模型,并对飞机撞击刚性墙的过程进行数值模拟。接着,采用Riera法对飞机撞击力进行理论计算,以验证数值模拟结果的准确性。最后,基于数值模拟结果对传统荷载时程分析方法进行改进,提出了可考虑不同撞击速度的荷载时程曲线调整方法以及加载区域确定方法,并对改进方法的有效性进行分析验证。结果表明:本文所提荷载时程分析改进方法简单有效,能够准确反映不同速度飞机撞击下刚性墙的最大位移响应,适用于重大工程结构的飞机撞击分析。
This paper focuses on the commercial aircraft impact on rigid wall. The finite element model for aircraft was first established and the numerical simulation of aircraft impact on rigid wall was carried out within the environment of ANSYS/LS-DYNA. The accuracy of the numerical simulation results was then verified by the Riera method. Finally, the traditional load time history analysis method was improved based on the numerical simulation results, in which a load time history curve adjustment method considering different impact speeds and a loading area determination method were proposed. Furthermore, the effectiveness of the improved method was proved. The results show that the proposed load time history analysis improved method is easy to implement and can accurately reflect the peak displacement response of rigid wall under the impact of aircraft at different speeds, which is suitable to aircraft impact analysis of major engineering structures.
