To analyze the mathematical nature of applied mathematics in colleges and universities, a method based on a model of big data mining algorithms is proposed. Firstly, the modeling is carried out through the deployment of nodes, which can accurately collect the characteristics of data information in the case of massive big data; secondly, the acquisition algorithm of multi-feature fusion is systematically optimized, which can avoid data interference and collect features quickly and accurately; thirdly, by transforming the multidimensional application-oriented university applied mathematics discipline model into an unlimited experience loss minimization problem with penalty factors, the improved support vector machine algorithm is used to construct and solve the objective kernel function. It is proved that the intelligent collection method based on big data mining algorithm model for the characteristics of applied mathematics in colleges and universities is effective. The sympathetic set corresponding to the flowing data is [115∼135]; the data similarity in big data environment is 1; in order to ensure that the intelligent collection method of applied mathematics discipline characteristics in colleges and universities based on big data analysis can collect data characteristics more accurately, which are 110/76.65/78/110, respectively.

A non-pneumatic tire (NPT) overcomes the shortcomings of a traditional pneumatic tire such as wear, punctures and blowouts. In this respect, it shows great potential in improving driving safety, and has received great attention in recent years. In this paper, a carbon fiber-reinforced polyethylene terephthalate (PET/CF) honeycomb is proposed as a support structure for NPTs, which can be easily prepared using 3D printing technology. The experimental results showed that the PET/CF has high strength and modulus and provides excellent mechanical properties. Then, a finite element (FE) model was established to predict the compression performance of auxetic honeycombs. Good agreement was achieved between the experimental data and FE analysis. The influence of the cell parameters on the compressive performance of the support structure were further analyzed. Both the wall thickness and the vertically inclined angle could modulate the mechanical performance of the NPT. Finally, the application of vertical force is used to analyze the static load of the structure. The PET/CF honeycomb as the support structure of the NPT showed outstanding bearing capacity and stiffness in contrast with elastomer counterparts. Consequently, this study broadens the material selection for NPTs and proposes a strategy for manufacturing a prototype, which provides a reference for the design and development of non-pneumatic tires.

“…Rugsaj built the Tweel model based on the transient dynamics method and performed a drum analysis, which can evaluate the dynamic response [4]. Sim et al designed a branch-shaped spoke structure, mainly to explore the impact of spoke shape, asymmetric spoke division, and symmetric spoke division on NPT bearing [5]. Jang et al used topology optimization to design support structures and obtained three representative structures, one of which was similar to Tweel, and the design freedom of support structures could be greatly improved by topology optimization [6].…”

Compared with pneumatic tires, non-pneumatic tires have incomparable performance, in terms of load bearing and safety. In this paper, the static load characteristics and pure longitudinal slip characteristics of the non-pneumatic tire are studied by combining experiments and simulations. The test results show that the radial stiffness of the original structure is nonlinear, the pure longitudinal sliding characteristics are seriously inconsistent, the brakes are very sensitive, and the driving is slightly soft. A series of designs have been carried out from the aspects of load-bearing mode and anti-symmetry of the structure, and numerical simulations have been carried out. The results show that the radial secant stiffness of the optimized structure II is increased by 58.8%, and the radial tangent stiffness is increased by 2.96 times, under the premise of ensuring the mass reduction. Additionally, the R square is 0.9932, and the linearity of the radial stiffness curve is greatly improved. The braking and driving conditions under pure longitudinal sliding characteristics are more antisymmetric, which greatly improves the braking sensitivity, but the driving performance is not as good as the original structure. In addition, this paper establishes the evaluation index of the non-pneumatic tire carrying mode, which lays the foundation for further exploration of the non-pneumatic tire carrying mechanism.
