Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] like figure 1 As shown, the vibration test tooling of traditional marine electromechanical equipment is simply composed of 2 first channel steels 1, 3 second channel steels 2, 2 third channel steels 3, 2 fourth channel steels 4, and 3 The fifth channel steel 5 and 4 sixth channel steels 6, a total of 16 channel steels are welded by continuous welding, the cross section of the channel steel is as follows figure 2 shown.
[0020] The local constrained damping layer vibration test tooling of the present invention is to install a single-layer constrained damping layer (such as image 3 shown) or multiple constrained damping layers (such as Figure 4 Shown), absorb the excess vibration energy on the tooling during the vibration test, especially the vibration component at the natural frequency of the tooling, so as to achieve the effect of suppress...
