Design and Fabrication of Impact Strength Machine

Aliemeke B. N. G., Ehibor O. G.


The development of the impact strength testing machine is successfully presented. The impact strength testing machine is necessary for ascertaining the strength of metallic components in withstanding applied load. A comprehensive design analysis was carried out to ascertain the various component sizes of the Impact strength testing machine in order to create a path for precise construction. Majority of the materials used in this fabrication were obtained locally.  The constructed machine yielded a maximum velocity of 4.9m/s on execution of Charpy and Izod impact test. Great stability was achieved as a result of thick base plate and column support used during construction. A crushing force of 68.05KN and an impactor head energy of about 35J was able to impart the requisite deformation on the metallic specimen needed for the Charpy and Izod tests.
