Embodiment Construction
[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] A high-frequency fatigue testing device, including two chucks 11 and a drive system, the two chucks 11 are arranged at a certain distance, and the two chucks 11 can fix a test sample 10 of micro-nano size to the two chucks 11 Between, this drive system can drive two collets 11 to do simple harmonic motion simultaneously along the line direction between two collets 11, and this drive system includes motor 13, as Figure 1 to Figure 3 shown.
[0022] Because the motor 13 is used to drive, the high-frequency fatigue test can be realized. In the high-frequency fatigue test device, the movement frequency of the chuck 11 is 50-1500 times per minute. In this embodiment, two chucks 11 are arra...
