Abstract
The present technology provides an impact test device and method. The rotational speed of a rotary drum with a rubber sample attached on the outer surface is set to a desired rotational speed, the impact cycle for the surface of the rubber sample of the contact member by the repeat-impact mechanism is set to a desired cycle, the impact load by the contact member is set to a desired impact load by a weight member, a desired contact member is selected from among the plurality of contact members with different specifications, and the contact member is repeatedly made to collide with the surface of the rubber sample by rotating a vertical excitation roller and pivoting the arm portion in the vertical direction with a rotation shaft.
