新型蝙蝠型负泊松比微结构非充气轮胎设计
Design on novel non-pneumatic tire embedded with bat-shaped cellular structure with negative Poisson's ratio characteristics
摘要
Abstract
To address the bursts and punctures of traditional pneumatic tires,this paper proposes a novel non-pneumatic tire with bat-shaped cellular structure(BSCS).First,the theoretical mechanical predictions comprising the relative density,specific energy absorption,and peak force for BSCS are derived,and quasi-static compression tests on BSCS sample is executed to verify the accuracy of mechanical models and simulation models.Then,the finite element model(FEM)of BSCS non-pneumatic tires is built,and the accuracy of tire FEM is verified with the adoption of quasi-static compression test.Finally,simulation analyses on grounding performance,three-way stiffness,modal analysis,cornering characteristics and steady-state rolling of non-pneumatic tires are conducted.Our results show the radial stiffness is 151.37 N/mm,the lateral rigidity 281.88 N/mm,and the longitudinal stiffness 686.05 N/mm on the proposed BSCS non-pneumatic tires,demonstrating they achieve excellent mechanical bearing capacity and reliability,which may provide insights for designing non-pneumatic tires.关键词
