Assessment of Dynamical Properties of Die Hammer MPM 10000 B Considering Deformations of Working Material

This paper presents an assessment of dynamic properties of a die hammer. The object of research is the steam-air die hammer MPM 10000 B that is considered taking into account the deformations of the working material. Based upon the technical specifications, two calculation models of the hammer were developed assuring the proper selection of the parameters. Next, the numerical simulations were performed, which results were presented in a graphical form as time histories of displacements and accelerations of particular elements of the hammer. It was demonstrated that the analyzed design of a die hammer has sufficiently low level of vibration amplitudes as well as their accelerations.
