Title:
THIN-WALLED ENERGY-ABSORBING CYLINDER AND BUCKLING MODE CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/128496
Kind Code:
A1
Abstract:
A thin-walled energy-absorbing cylinder. The thin-walled energy-absorbing cylinder comprises a cylinder body, which comprises a front end for receiving an axial impact load and a rear end opposite to the front end, and starting from the front end of the cylinder body, a plurality of circumferential annular grooves are alternately arranged on the outer and inner walls of the cylinder body. By arranging initial defects, that is, the annular groove, in the longitudinal direction on the thin-walled cylinder, the device can effectively control the buckling mode and plastic hinge forming position of the thin-walled cylinder, and then through control of depth change, width, spacing, and the like of the groove, the buckling collapsing process can be effectively controlled, achieving controlled optimization of axial compressional buckling energy absorption space of the thin-walled cylinder. A buckling mode control method for the thin-walled energy-absorbing cylinder is also provided.
