Water-cooled high-temperature vibration test switching tool

Abstract

The invention relates to a water-cooled high-temperature vibration test switching tool which comprises a disc-shaped tool body, two water pipe connectors are symmetrically arranged on the circumferential side face of the tool body, and a plurality of counterbores used for being fixedly connected with a vibration table and a plurality of threaded holes used for being fixedly connected with a test piece are formed in the end face of the tool body at intervals. On the end face, the counterbores and the threaded holes form an inner ring and an outer ring which are concentric, an inner ring coolingwater way and an outer ring cooling water way are formed in the tool body, and the inner ring cooling water way and the outer ring cooling water way are concentric with the tool body and communicatewith the tool body. A double-layer annular water path design is adopted, a cooling water path has no dead angle at 360 degrees, the flow and the proportion of the inner and outer ring cooling water ways can be adjusted by adjusting the hole diameters of the inner and outer ring cooling water ways, the temperature field of the tool is changed, and the optimal cooling effect is achieved.

Description

technical field [0001] The invention relates to a water-cooled high-temperature vibration test adapter tooling, which belongs to the field of high-temperature vibration tests. Background technique [0002] In the process of re-entering the atmosphere, the high-speed aircraft needs to bear the ultra-high aerodynamic thermal load and vibration load. Carry out high temperature vibration ground test. During the high-temperature vibration test, a rigid connection is required between the tooling and the vibrating table, but the increase in temperature of the tooling will lead to a decrease in the stiffness and strength of the tooling, and at the same time, excessive temperature may also cause the vibrating table to fail, so the tooling and the vibrating table need to be taken Cooling or insulation measures. In previous tests, flexible thermal insulation adhesives were usually used for heat insulation, but the use of flexible thermal insulation adhesives will affect the transfer ...

AI Technical Summary

Problems solved by technology

During the high-temperature vibration test, a rigid connection is required between the tooling and the vibrating table, but the increase in temperature of the tooling will lead to a decrease in the stiffness and strength of the tooling, and at the same time, excessive temperature may also cause the vibrating table to fail, so the tooling and the vibrating table need to be taken cooling or insulation

In previous tests, flexible thermal insulation adhesives were usually used for heat insulation, but the use of flexible thermal insulation adhesives will affect the transfer characteristics of the test piece, and the thermal insulation effect will decrease in a long-term thermal environment. Vibration connection tool that does not affect the transfer characteristics of the test piece and meets the requirements of long-term high-temperature vibration tests
