该文提出了三种新型的诱导结构设计方案来降低薄壁方管结构在轴向载荷作用下的初始屈曲载荷峰值。诱导结构设计在方管的加载端,在压缩开始的时候起作用,并且不会显著影响结构在正常工作时的强度和刚度。利用AA 6063 T6铝合金薄壁方管进行了一系列准静态和动态试验来研究了具有诱导结构的方管在轴向压缩时的能量吸收性能,给出了完整薄壁铝方管和具有诱导结构的薄壁铝方管的载荷位移曲线,并进行了比较。实验发现,三种诱导结构均可有效降低屈曲时的初始载荷峰值、提高方管承载吸能平稳性。 In this paper, three new types of induced structures are proposed to reduce the initial buckling load peak of thin-walled square-tube structure under the axial load. The induced structural design at the loading end of the square tube works at the onset of compression and does not significantly affect the strength and stiffness of the structure during normal operation. A series of quasi-static and dynamic tests were carried out on AA 6063 T6 aluminum alloy thin-walled square tube to study the energy absorption performance of the square tube with induced structure under axial compression. A complete thin-walled aluminum square tube with induced structure Thin-walled aluminum square tube load displacement curve, and compared. The experimental results show that the three induced structures can effectively reduce the initial peak load during buckling, and improve the stability of square tube bearing energy absorption.
