Electrodynamic Vibration Test Apparatus with Replaceable Horizontal Slide Table

Abstract

An electrodynamic vibration test device with a replaceable horizontal slide table is characterized in that it includes a machine base, a vibration table and at least two horizontal slide table assemblies; the vibration table is arranged at one end of the machine base, and the other end of the machine base A horizontal sliding platform installation area is provided on the horizontal sliding platform, and fastener connecting holes are arranged on the horizontal sliding platform installation area; the horizontal sliding platform components include a table top, a guide bearing mechanism and a fixing plate, and the fixing plates of each horizontal sliding platform component correspond to Fasteners are provided in the fastener connection holes on the installation area of ​​the horizontal slide table, so that each horizontal slide table assembly can be replaced and fixedly installed on the horizontal slide table through the connection between the fasteners and the fastener connection holes. area, when the vibrating table is flipped to a horizontal position, its moving coil is rigidly connected to the table surface of the installed horizontal sliding table assembly. The invention does not need to modify the vibrating table body, and can realize the test requirements of test pieces with different specifications by replacing the horizontal sliding table components, and is suitable for horizontal vibration tests with test pieces with multiple specifications and multiple test indexes.

Description

technical field [0001] The invention relates to an electrodynamic vibration test device in environmental mechanics tests, in particular to an electrodynamic vibration test device with a replaceable horizontal slide table. Background technique [0002] In the field of vibration test technology, when the test piece needs to vibrate in the horizontal direction, it is necessary to configure a horizontal slide table to meet the test requirements in the horizontal direction. Traditionally, an electrodynamic vibration test device that can be used for horizontal direction vibration tests is sold to users by installing an electrodynamic vibration table and a horizontal slide table on the same machine base to form an integral body. During the test, the specimen is installed on the table of the horizontal slide table, and the moving coil of the electric vibration table is rigidly connected with the table of the horizontal slide table through the joint, that is, the table of the horizon...

AI Technical Summary

Problems solved by technology

[0005] (1) When switching the horizontal slide table, it is necessary to flip the vibrating table, which involves the flipping of water pipes (water-cooled vibrating table) or air pipes (air-cooled vibrating table), oil pipes and wires. This switching operation is very cumbersome and time-consuming;

[0006] (2) The machine base 1 needs to be enlarged, and the area occupied by the vibration device increases;
