In addition, due to the irregular shape of the server fan, it cannot be directly fixed on the vibration table for vibration testing. Utility Model Content

[0042] The fans of current servers are all installed on the server model for vibration testing, which is more of a test of the overall vibration resistance of the server, and cannot effectively test the vibration resistance of the fan unit. At the same time, due to the irregular shape of the server fan, it cannot be directly fixed on the vibration table for vibration testing. In addition, during the vibration test, it is necessary to simulate the actual installation and tooling status of the fan in the server, which is impossible to achieve with the current test tooling.

[0043] To this end, the present application provides a vibration testing tool, which includes a vibration table and an installation bin 100. The installation bin 100 has a cavity 110, and the cavity 110 is used to accommodate and install the fan 500 under test. Through holes 120 are provided on two cavity walls opposite to each other of the cavity 110, and the through holes 120 are used to allow external airflow to flow into the cavity. The vibration table is connected to the installation bin 100 to drive the installation bin 100 to vibrate.

[0044] The vibration test fixture is provided with the fan 500 to be tested in the cavity 110 of the installation chamber 100, and through holes 120 are provided on two oppositely arranged cavity walls of the cavity 110, and the through holes 120 connect the cavity 110 with the outside, thereby providing airflow when the fan 500 to be tested is working. The installation chamber 100 is connected to a vibration table, and the vibration table can drive the installation chamber 100 and the fan 500 to be tested installed in the installation chamber 100 to vibrate synchronously, thereby testing the vibration resistance performance of the fan 500 to be tested.

[0045] Specifically, as shown in Figures 1 and 2, the through hole 120 is octagonal in shape. The through hole 120 is set to be octagonal in shape, which increases the area of ​​the through hole 120 and also increases the air intake volume.
