Triaxial synthesis oscillation/impact test device

[0010] refer to figure 1 , The three-axis comprehensive vibration / shock test device includes a vibration table body 1, a base 2, and an extension table assembly 3.

[0011] The structure of the vibrating table body 1 is the same or similar to the existing hydraulic or electromagnetic vibrating table. The vibrating table body 1 is installed on the base 2 of the vibrating table surface through a fixing device, and the corresponding extended table surface is in an inclined state, that is, vibrating The axis 10 of the table body 1 (including the excitation source) and the vertical line form an inclination angle θ (such as figure 1 As shown), this structure can decompose the vibration in a single direction along the axis 10 of the shaking table body into the components of any axis on the three-dimensional coordinate axis, that is, one vibration test can meet the requirements of three-dimensional axial test. Compared with the traditional test The vibration excitation in one coordina
