A high-frequency anti-water-leakage satellite vibration test clamp (1) for large interface expanding is mainly used for expanding the interface size of phi 990mm of a vibration platform to be more than double so as to adapt to installation of a large interface of more than phi 2000mm of a satellite, and is capable of preventing the vibration platform from being damaged by water leakage of a satellite water tank. Furthermore, the high-frequency anti-water-leakage satellite vibration test clamp can meet the requirements of a satellite high-frequency vibration test when first-order resonance frequency of the clamp reaches more than 200Hz. Under the condition that the height and the quality are controlled, the clamp expands the original interface (2) of phi 990mm to be more than double and enables the interface to be an interface (3) of phi 2100mm in a mode that the number of lightening holes of an entity is increased or decreased, high rigidity and frequency are ensured, and the defects that the height cannot be reduced due to a rib plate type clamp without a large expanded interface and accordingly the frequency and the rigidity are remarkably reduced are overcome. A top inclined plane (4) of the clamp inclines from the center to an edge lightening hole and is combined with an edge slant lightening hole (5), a central blind hole type lightening hole (6) and a flow guide groove (7) to enable water leaked from the satellite water tank to flow along the top inclined plane and to be led out of a vibration platform range through the gradient of the edge lightening hole, thereby protecting and preventing vibration platform from being damaged by leaked water and removing complicated work of waterproof cover paving on the clamp due to the fact that an original clamp aims at protecting the vibration platform. The high-frequency anti-water-leakage satellite vibration test clamp for the large interface expanding has the advantages of being low in manufacture cost, excellent in performance, convenient and visual in use, strong in adaptability and generality and the like.
