In order to impprove the protective effect of the automotive energy absorption (EA) box, the design of the reentrant bioinspired EA box is proposed, that is, novel bioinspired structures are inserted into the original EA box to improve the EA effect of the box. The improved bionic structures with curvature are designed according to the spider web: honeycomb structure (HS), arc-honeycomb structure (AHS), negative Poisson structure (PS), and arc negative Poisson structure (APS). A new bionic automobile energy absorbing box is constructed by combining with automobile energy absorbing box. Experiments and simulations further verify excellent mechanical properties of bionic structures. The results show that EA of AHS and APS is 117.2% and 105.8% of HS and PS. Their specific energy absorption is 112.2% and 102.7% of HS and PS. HS EA box structure, AHS energy absorption box structure, PS energy absorption box structure, and APS energy absorption box structure are 114.2%, 117%, 109.2%, and 116.2% higher than traditional EA box structures, respectively. The excellent characteristics of biological structures can provide ideas for structural design objectives of engineering applications and greatly simplify the process of optimal design.

Since the existing research focusing on the measurement of periphery is basically on the definite periphery, the research on the uncertain periphery is rarely involved. The following work has been carried out in this paper. Firstly, the concept and algorithm of interval-valued vague set (IVVS) of periphery element’s guard degree and exchange degree are given; Secondly, using the interval-valued aggregation operator, the calculation method of the total guard degree and the total exchange degree of the periphery elements based on the interval-valued vague set is given. By calculating the security degree and the survival degree of the periphery set, the quantitative evaluation value of the periphery is obtained, and the model of using the periphery to evaluate the system is given. Finally, an evaluation example is given to verify the effectiveness and practicability of the evaluation model.
