The utility model belongs to the technical field of thermal vibration tests and provides a water-cooled high-temperature vibration test fixture with an aim to solve the technical problem that high temperature can lead to intensity weakening of test tooling materials. The water-cooled high-temperature vibration test fixture comprises an upper end face (1) is internally provided with a plurality of cooling water ducts, a lower end face (2) connected with the table board of a vibration table (5) and side walls (3) connected with the upper and lower end faces; both the upper end face (1) and the lower end face (2) are provided with a plurality of mounting holes, the mounting holes in the upper end face (1) are used for mounting of test articles (6), and the mounting holes in the lower end face (2) are used for mounting of the vibration table (5). The water-cooled high-temperature vibration test fixture has the advantages that thermal transmission of the test articles (6) to the vibration table (5) can be continuously efficiently stopped during tests, normal operation of the vibration table (5) can be guaranteed, and requirements on high-temperature vibration tests can be totally met.
