PROBLEM TO BE SOLVED: To enable dynamic compression property of a test piece to be directly acquired with a simple device configuration.SOLUTION: A dynamic compression property test machine 1 comprises a test piece installation part 2 for installing a test piece T of a structure at a fixed position, a collision body 4 which falls on the test piece T from a predetermined height and collides with the test piece, a collision body fall mechanism 3 for making the collision body 4 fall, an acceleration sensor 5 attached to the collision body 4, for measuring acceleration of the collision body 4 at the time of falling, a displacement meter 6 provided at a lower part of the test piece T, for measuring displacement of the test piece T at the time of collision with the collision body 4, and a calculation unit 8 for calculating dynamic compression property of the test piece T with input of data D1 and D2 from the acceleration sensor 5 and the displacement meter 6.SELECTED DRAWING: Figure 1 |
