A horizontal vibration test device that can directly hang the test piece

Abstract

The invention relates to the technical field of mechanical environment tests and particularly discloses a horizontal vibration test device capable of directly hanging a test piece. The test device comprises a vibration table, a horizontal slip and a hanging fixture, wherein the vibration table is fixedly connected with the horizontal slip through a connector; the hanging fixture passes through and is arranged on the horizontal slip, and the lower end can clamp the test piece; through changing the mounting direction of the hanging fixture on the horizontal slip, axial or radial mounting of the test piece is realized; through reciprocating vibration of the vibration table, the hanging fixture on the horizontal slip and the test piece clamped at the lower end are driven to perform reciprocating vibration in the axial or radial direction. High requirements on equipment when a horizontal vibration test is carried out on a rack-like product through large fixture transit presently can be solved, influences on a test piece test result by modal characteristics of the large fixture are reduced, and besides, the horizontal vibration test device can also complete a horizontal vibration test on a conventional product according to needs, and the application range and the test ability of the existing horizontal slip are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical environment tests, in particular to a horizontal vibration test device which can directly mount test pieces. Background technique [0002] The vibration test system can simulate the actual working conditions of the test piece, and is mainly used for reliability tests such as product vibration intensity, impact environment test, and environmental stress screening test. It has been widely used in various industries such as aerospace, aviation, automobiles, electronics, and ships. . [0003] The horizontal vibration test device is the necessary supporting equipment for the horizontal vibration test of the vibration test system. It is the mechanical support device that transmits the vibration of the shaking table to the test piece during the vibration test process. It is an important part of a complete vibration system. The horizontal slide table is a common horizontal vibration test device, which...
