内容記述 | By combining the horizontal vibration table with the vertical vibration table, both constructed last year, in a suitable way, it was possible for us to get a new vibration table with simultaneous horizontal and vertical motions. The horizontally moving part was driven by a Leonald motor of 1 H.P. and the vertically moving part by a three phase commutator shunt motor of 1/2 H.P. In the present case, no spring was fitted between the motor driving system and moving table for the vertical vibration and also for the horizontal vibration, as the result of which the ranges suited to practical use could be made fairly wide. Experimental tests of the table showed that although the horizontal and vertical amplitudes remain constant for any exciting frequency in vertical motion, the same amplitudes change with differences in the frequency of the horizontal motion. At all events, it was found that the practical range of vibrational frequency in the horizontal sense was from one to ten per second and that in vertical sense from one to five per second. In the present case no damper was used. Were an effective damper added, the range of frequency to be applied would be much wider. | |||||
