DEPENDENCY OF TEMPERATURE ON WOODEN MATERIALS’ MECHANICAL PROPERTY AND EFFECT OF IMPACT ENERGY ABSORPTION OF SHOCK ABSORBERS

A series of drop tests with a full scale drop test model and a 1/2.5 scale drop test model for “MSF cask (Mitsubishi Spent Fuel Cask)” were conducted. Shock absorber compression tests were conducted at room temperature and at high temperature as well to confirm a temperature dependency of compression properties. This paper indicates shock absorber compression test results concerning compression properties and their temperature dependency for shock absorber.
