FIELD: machine building.SUBSTANCE: vibration exciter of oscillations of mechanical structures consists of housing, power drive, resilient hinges, rod connected to flexible link. Rod of power drive is connected by flexible link with movable platform with replaceable load, which is installed on elastic hinge consisting of two intersecting at an angle 90° elastic plates connecting movable platform with housing. Power drive is installed on another resilient hinge, having shape of an isosceles trapezoid, lower base of which is fixed on base of housing, and on its upper base power drive is fixed, wherein at extension of sides of trapezium an angle is formed in range of 70-100°, wherein its vertex is located on axis of rod of power drive, which is perpendicular to geometrical axis of oscillations of resilient hinge.EFFECT: disclosed is a vibration exciter of oscillations of mechanical structures.6 cl, 10 dwg |
