Трикоординатний вібростенд

Abstract

A three-axis vibration stand comprises a vibroinsulated base frame, on which vibrators are located, which are installed on mutually perpendicular directions, and elastic elements of high rigidity in the direction of transmission of vibration and low stiffness in the perpendicular direction, which are clamped between a platform and a vibrator. It additionally comprises a U-shaped vibrating hopper, which is mounted on three elastic elements, three-pressure pulse generators and three hydraulic cylinders, each of which is located at an angle of 10° to three main orthogonal planes and connected to an appropriate pressure pulse generator.
