Abstract
Energy absorbers are used frequently in industrial machinery. The use of energy absorbers allows for the design of a lighter structure while still maintaining the requisite dynamic stiffness for effective operation. A standard energy absorber used on a CNC machine is investigated in this paper. The absorber is connected to a rigid mass to establish fixed boundary conditions at the joint face. Numerous dynamics tests are performed on the absorber and the Acceleration Surface Method applied to assist in the comprehension of the form of the nonlinearity.
