Large-scale structure clamped boundary vertical vibration test system and use method

Abstract

The invention provides a large-scale structure clamped boundary vertical vibration test system and a use method, and belongs to the technical field of vibration environment tests. The vibration test system comprises a vibration loading table, guide devices, vibration loading devices and a gravity balance system; the whole vibration loading table is of a plane symmetry structure, adopts a structural form that an aluminum pipe is clamped by double-layers of aluminum plates, and comprises an upper plate, a lower plate, a central pipe and a steel tank; the two sets of guide devices are respectively fixed at the two ends of the opposite angles of the vibration loading table, and each guide device comprises a guide column, a guide rail and a bracket; each vibration loading device comprises an expansion tool, a hydraulic ball head and a vibration table, and each set of vibration loading devices comprises two hydraulic ball heads which are arranged in the width direction of the vibration loading table; and the gravity balance system comprises a bearing support, a hoist, a rubber rope set and a sling. The invention further provides a using method of the vibration test system, and the problem that long-time stable loading cannot be achieved due to the transverse cross-linked vibration of the vibration loading table in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of vibration environment tests, and in particular relates to a large-scale structure fixed support boundary vertical vibration test system and a use method. Background technique [0002] The structure of large-scale equipment and the adaptability and reliability of equipment in the vibration environment within the use profile are related to important issues such as reducing the failure of equipment structure and equipment, ensuring its use efficiency, and ensuring equipment safety. Vibration environment test technology is an important means to verify and solve the adaptability and reliability of the test piece structure and equipment vibration environment. The vibration loading of the fixed support boundary of large structures generally adopts the multi-vibration table uniaxial test system configuration, and the vibration loading table is used to simulate the fixed support boundary of the test piece, and the...
