内容記述タイプ Abstract
内容記述 For the use of a Tip Ball type indenter in the various Rebound Hardness Machines or Methods, it is necessary to investigate the influence of the holding shaft of an indenting sphere on the relative equations of Rebound Hardness. For this purpose, firstly the Tip Ball type indenter's vibratory system is considered and concluded with the vibratory model of one degree of freedom by the theory of vibration, and shown that in this model, if the ratio of natural period of an indenter to the duration time of impact is very small, the movement of a holding shaft is preportional to the impact force. Therefore the energy stored in a holding shaft during impact can be calculated easily, being equal to the total of this energy and the energy of the contact areas of an indenting sphere and a material using Hertz's Contact Law to the rebound energy of an indenter. The equation of the rebound energy of a Tip Ball type indenter is shown. Next, the results of experiments with several Tip Ball type indenters are given and clarify quantitatively that measured values are consistent with the analyzed values within an accuracy of about ±5% and the influences of a holding shaft are larger as the falling height becomes higher, and the material becomes softer. Finally, the above mentioned points of that influence are confirmed for the Hardness Number by the experiment using the indenter of the D type Shore Hardness Testing Machine.
