More stable scientific research vibration experiment platform

Abstract

The invention relates to the technical field of vibration devices, in particular to a more stable scientific research vibration experiment platform which is characterized in that the platform comprises a vibration box body, vibration motors, a positioning frame and a controller, the positioning frame is arranged in the vibration box body; the two vibration motors are symmetrically arranged on the positioning frame; the vibration box body is a square frame and comprises a working platform on the top, side plates on the two sides and a bottom plate, elastic ground feet are arranged at the four corners of the bottom plate, mounting clamping grooves used for fixing working parts are formed in the working platform, and positioning holes are correspondingly formed in the two sides of the positioning frame, the side plates and the bottom plate; and the angle of the exciting force of the motor can be changed by adjusting the inclination angle of the positioning frame relative to the bottom plate, so that different forms of vibration are generated. The platform has the advantages that by changing the fixing mode of the positioning frame, the experiment requirements of circumferential shimmy or linear vibration and combined vibration in the horizontal direction are met, experiment equipment does not need to be replaced, the structure is simple, one machine has multiple purposes, and better economical efficiency and applicability are achieved.

Description

technical field [0001] The invention relates to the technical field of vibration devices, in particular to a more stable scientific research vibration experiment platform, which can realize multi-angle linear vibration and horizontal circular shimmy vibration, and meet the needs of any or combined vibration experiments. Background technique [0002] The research on the dynamics of particulate matter under different vibration forms has always been a hot topic in the eyes of scholars. The existing vibration experiment platforms on the market can only achieve a single vibration. Different vibration experiments require different vibration equipment, and in combination vibration During the experiment, the experimental platform needs to be replaced. Since the object of the experiment is often discrete element particles, it is difficult to ensure the particle configuration when changing the platform. Due to the great difference in the working parts of different types of experiments...
