Abstract
An impact test apparatus allows a retaining member to retain a test object. The retaining member is attached to an elastic member. When a weight is made to collide against the test object, impact is applied to the test object. The test object is subjected to free oscillation in response to the impact. The elasticity of the elastic member accepts the movement of the retaining member. Damping of the free oscillation of the test object is minimized. The impact test sufficiently reflects the influence of the free oscillation.
