Abstract To solve the problem of high energy absorption conflicting with small load fluctuation, a multi-tube combined energy absorption structure with induced ring based on the load curve staggered compensation strategy was proposed. The effects of the number, height, and thickness of the induced rings on the load curve trend were investigated by experiment and simulation, and the initial structural parameters suitable for the design of load curve staggered compensation. were determined. Then, the influences of height difference and induced ring distribution on the load curve trend were revealed, and the control method that can make the appropriate difference in each tube load curve was summarized. Moreover, the diagram of the correlation between the key multi-tube combination parameters and the load curve control effect was plotted based on classical theory and the acquired temporal influence. Finally, a multi-tube structure with suitable height difference and variable induction ring distribution was proposed. Compared with the multi-tube structure with the same configuration parameters, the combined structure proposed in this study decreases the initial peak and load fluctuation by 49.45% and 58.93%, respectively, while maintaining a high energy absorption.
Highlights The initial structural parameters of the induced ring are determined. The influence law of height difference on the load curve is analyzed. The influence law of induced ring distribution on the load curve is revealed. The load curve control effect of key combination parameters is obtained. The design idea of load curve staggered compensation is proposed.
