The invention provides a vibration clamp comprising a clamp body which is provided with an installing surface and a connecting member which is fixed on the installing surface through a locking structure and used for fixing a product. The clamp body is provided with three bottom surfaces which are connected with vibration equipment. Every two of the three bottom surfaces are adjacent and perpendicular. The clamp body is also provided with three surfaces of which every two surfaces are adjacent. Only one of the three surfaces is the installing surface, and the three surfaces and the three bottom surfaces are corresponding in a one-to-one way. The three surfaces are arranged along three directions in which every two of the three surfaces are perpendicular. Any one bottom surface is adjacent to other two bottom surfaces and two surfaces. The overall center of gravity of the clamp body, the locking structure and the connecting member is enabled to be equal in the distance to the three bottom surfaces by arranging the weight of the clamp body, the locking structure and the connecting member. According to the vibration clamp and a vibration test method, the installing requirements of multiple products can be met; time consumed for changing direction is less; the vibration force transmission order is reasonable; and the product is not damaged due to repeated product disassembling and assembling.
