Embodiment Construction
[0036] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0037] Such as Figure 1 to Figure 6 As shown, the present invention provides a composite material dynamic fatigue test device based on reverse resonance, including a double cantilever beam vibration test system, an electronic acquisition system and a measurement and control system;
[0038] The double cantilever beam vibration test system includes two cantilever vibrating beams 2, an eccentric motor 3 and a base plate 24, the left side fixed plate 1 is fixedly installed on the left side of the top of the base plate 24, and the right side fixed plate is ...
