IMPACT TESTING MACHINE

摘要

PURPOSE: An impact tester for a support grating of a nuclear fuel assembly is provided to accurately measure impact strength by minimizing the heat transmission to a load cell through a heat sink plate and a cooling member. CONSTITUTION: A support grating piece is received in a space part(11) of a body(10). A piece fixing unit is arranged on the rear of the body. An opening unit(12) is formed on the front of the body to be connected to the space part. A hitting unit includes an impact hammer(20) and a pair of support stands(22). The impact hammer is movably connected between the pair of support stands by a pendulum. A sensing unit includes a load cell. When the impact hammer hits the support grating, the load cell measures the impact strength of the load cell.
