TWO-FREEDOM VIBRATOR

摘要

PURPOSE:To perform a two-freedom vibration by connecting a vertical vibration rod and a rotary vibration rod with a connecting plate to form a parallel link mechanism, with which a vertical reciprocating motion while a reciprocating rotary motion centered on the connection point. CONSTITUTION:A vertical vibration rod 12 is controlled in the movement vertically and a pair of rotary vibration rods 14 are arranged parallel with the rod 12. One end of the rod 12 is connected to any position on the axis of a test object 10 directly or indirectly while one end of the rod 14 is connected a position on the side thereof 10 directly or indirectly. Other ends of the rods 12 and 14 are connected to each other through a connecting plate 20 to form a parallel link mechanism. A driving force by a motor 34 is turned to a vertical motion at the connection point 22 between the connecting plate 20 and the rod 12 through a link 24 to vibrate the test object 10 vertically. A driving force by a motor 54 is turned to a reciprocating rotary motion centered on the connection point 22 to impart a rotary vibration to the test object 10.
