FIELD: educational aids. SUBSTANCE: movable striking member 8 is sliding in the course of vibration of damped object 5 relative to guide channel 7; this sliding motion is synchronized with external excitation. Movable member 8 strikes twice ends of guide channel 7 during each vibration of damped object 5 with the result that it creates periodic impulse load acting on damped object 5 in phase opposition to vibration load. In the action, vibration amplitude of damped object reduces and object 5 is stabilized in position. EFFECT: enlarged demonstration capabilities, improved visualization of process. |
