| 摘要： | Under the Transportation Recall Enhancement, Accountability and Documentation (TREAD) Act, the National Highway Traffic Safety Administration (NHTSA) was assigned the task of revising and updating the Federal Motor Vehicle Safety Standards (FMVSS) for tires. This effort included research to support a possible update or replacement of the current tire strength (also referred to as plunger energy) test in FMVSS Nos. 109 and 119. The FMVSS Tire Strength Test was designed in the 1960s to evaluate the strength of the reinforcing materials in bias-ply tires and their resistance to road hazards. The test consists of forcing a 19-mm (-inch) diameter cylindrical steel plunger with a hemispherical end perpendicularly into to the centermost tread rib of a mounted and inflated tire at the rate of 50-mm (2inches) per minute. This is repeated at five equally spaced points around the circumference of the tire. To pass the test, the average energy of the test points must exceed the appropriate minimum breaking energy specified for that tire. |
