  • In this paper, various tire blow-out force experiment data were collected and analyzed to obtain approximate values of related coefficients such as rolling resistance, self-aligning torque, cornering stiffness, and radial stiffness for the analysis of the motion of vehicles with tire blow-outs. These coefficients related to tire blow-outs were input into a vehicle accident analysis program to simulate and examine the effects of tire blow-outs. Various configurations and velocities of vehicle collisions without tire blow-outs were also used as reference to establish collision events of vehicle collisions with tire blow-outs. For the events, the simulation analysis was performed and collision characteristics were obtained. Consideration of tire blow-outs or damages suggested in this study will greatly contribute to more reliable vehicle accident reconstructions.

  • 타이어가 펑크가 나도 림에서 이탈되지 않고 일정한 속도로 일정한 타이어 수리지점까지 주행할 수 있는 타이어 즉, 안전타이어(Run-flat tire)의 시제품을 최근 각 타이어메이커에서 만들고 있다. 그러나 아직은 실용화 단계는 못되었다. 81년 Toyo고무와 Nissan 자동차의 공동연구에서 동 Runflat 타이어 개발에 성공하였다. 본고는 동사에서 개발한 "Duraflat"의 상품명으로 판매되고 있는 "안전 타이어"에 대해서 여러가지 기술적인 면을 살펴보고자 한 것이다. <편집자 주>

  • A Non_Pneumatic tire (NPT) has spoke to replace air of the pneumatic tires. A NPT appears to have advantages over the conventional pneumatic tire in terms of flat proof and maintenance free. And a NPT can also be used in the space environment since it uses no air for inflation. In this study, the static contact pressure of NPTs with auxetic honeycomb spokes is investigated as a function of vertical loading and is compared with that of a pneumatic tire. The finite element based numerical simulation of the local stress of an airless tire is carried out with ABAQUS for varying vertical force and honeycomb spokes geometries.

  • Unlike existing pneumatic tire, NPT(Non-Pneumatic Tire) is a tire replacing air pressure with spokes. NPT has no problem of punk which pneumatic tire has and doesn't need to maintain air pressure. Also it can be used in space where temperature change sharply. In this regard, NPT are attracting attention as next-generation wheels. For optimizing Honeycomb structure, we applied the load to various Honeycomb structure which forms NPT, performed FEM(finite element analysis) using Edison and compared each results.
