| 摘要： | Approximately 30% of all vehicle related fatalities that occur each year are caused by a single vehicle leaving the road and striking a fixed object; the most common objects struck being trees, guardrails, and utility poles. In many cases current crash cushion systems are not cost effective to be installed on such obstacles. In addition to high initial costs many crash cushions require extensive maintenance or require expensive replacement parts driving costs up even more. This makes the development of a more cost-effective crash cushion a necessity. The objective of this study was to propose an initial design for a low-cost, reusable crash cushion using recycled materials. Used tires and tire-derived materials were tested in both static and dynamic modes to evaluate their application in a crash cushion. Both the tires and the tire-derived materials proved to be able to sustain high loads and proved to be durable, making them good candidates for use in a crash cushion. However, the tire-derived pads had excessively high loads per unit deflection, which would prohibit their use in a crash cushion. This problem could be eliminated if voids were added to allow material to deflect more under loading. The whole used tires could be used effectively as energy absorbing elements in crash cushions or truck mounted attenuators if compressed horizontally or vertically. |
