Abstract

The invention discloses a two-shaft vibration test device with an integrated base, which is provided with a working table, wherein the working table is connected with a moving coil table of a vertical electric vibration table through a first vibration transmitting and decoupling mechanism in the vertical direction, and is connected with a moving coil table of a horizontal electric vibration table through a second vibration transmitting and decoupling mechanism in the horizontal direction. The two-shaft vibration test device is characterized in that the magnetic cylinder part in the vertical electric vibration table body horizontally extends to form a base body, the top surface of the base body is used for bearing the horizontal electric vibration table, and the table body of the horizontal electric vibration table is arranged on the top surface of the base body. When the device is mounted, the base body, namely the magnetic cylinder part of the vertical electric vibration table is directly is connected with a foundation or contacted with the foundation through a vibration damping device; and the height difference from the top surface of the base to the working table surface can be calculated during the designing, the mounting height of the horizontal electric vibration table can be determined through the height difference, and the difficulty for mounting and debugging is greatly reduced.

Description

technical field [0001] The invention relates to mechanical environment test equipment, in particular to a two-axis vibration test device. The two-axis vibration test device can be used to simulate a vibration environment where each axis vibrates independently, and can also be used to simulate a compound vibration environment where two horizontal and vertical axes vibrate simultaneously. Background technique [0002] The purpose of the vibration environment test is to artificially simulate the impact of the vibration environment that the specimen may experience during transportation, storage, and use in the laboratory, and to assess its adaptability. When the stress caused by vibration is too large, the structure will crack or even break, especially in the resonance state. Long-term random vibration will cause fatigue damage to the structure due to the cumulative damage caused by alternating stress. Vibration can also lead to bad contacts, mutual contact or disconnection of...
