Abstract
A testing apparatus and method for determining the impact an/or vibration absorbent characteristics of an impact and/or vibration absorbent material. The apparatus includes a base having upwardly extending vertical guide rods. A sample plate is maintained in a position above the base by one or more springs of known spring rate. A weight is adapted to move vertically along the guide rods and to impact the sample plate and a sample of impact and/or vibration absorbent material when dropped from a raised position. The impact of the weight causes a downward vertical displacement of the sample plate, which displacement is measured by a moveable indicator. This displacement can be used, along with the total spring rate provided by the spring(s), to calculate a pass-through impact force. The pass-through impact force can then be subtracted from the impact force generated by the falling weight to determine the amount of impact force absorbed by the impact and/or vibration absorbent material.
