摘要： A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle; the vehicle impact attenuator comprising: a shock absorber (10A) that deforms upon a collision by a vehicle to reduce the impact on the vehicle; a support (20A) for the shock absorber (10A); and a holding portion (30A) that holds the support (20A) in a vertical position in the installation area; the support (20A) having cuts (31A) that, upon application of a load equal to or exceeding a set value, fracture and function as a release portion to thereby release the support from being held in a vertical position in the installation area; and the support (20A) being plastically deformable by a load less than the set value.

摘要： A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle. The vehicle impact attenuator includes a shock absorber that deforms upon a collision by a vehicle to reduce the impact on the vehicle. A support is provided for the shock absorber and a holding portion holds the support (20A) in a vertical position in an installation area. The support has cuts made in it that upon application of a load equal to or exceeding a set value, fracture and function as a release mechanism to thereby release the support from being held in a vertical position in the installation area. The support is deformable by a load less than the set value.

摘要： Disclosed is a vibration test method for evaluating the vibration resistance of a specimen, comprising a test specification setting step (S10) of determining reference vibration conditions for the specimen based on transport conditions during actual transportation; a reference value attainment step (S20) of calculating an amplitude level and a reference accumulated fatigue value of the specimen under the reference vibration conditions; a test condition determination step (S30) of determining test vibration conditions and a test time based on an allowable amplification factor of the amplitude level and a desired vibration time, so that an accumulated fatigue value which is calculated from the vibration detection value of the specimen satisfies the reference accumulated fatigue value; and a vibration-imparting step (S40) of vibrating the specimen based on the test vibration conditions and the test time. In accordance with the vibration test method, a vibration test that conforms to the actual transportation environment can be readily performed with high accuracy.
