The utility model provides a vibration test stand which comprises a rack, a vibration platform, a supporting guide pillar assembly, an auxiliary guide pillar and an auxiliary guide sleeve, wherein the supporting guide pillar assembly is connected with both the rack and the vibration platform; the auxiliary guide pillar is connected with the vibration platform; the auxiliary guide sleeve is arranged on the rack; and the auxiliary guide pillar is sheathed into the auxiliary guide sleeve. According to the vibration test stand, the auxiliary guide pillar and the auxiliary sleeve are added on the basis of the original supporting guide pillar assembly to share the side force suffered by the supporting guide pillar assembly, so that the side force suffered by the supporting guide pillar assembly is lightened and the supporting guide pillar assembly is not easy to be damaged by strong side force, and thus the service life of the supporting guide pillar assembly of the vibration test stand is prolonged.
