This utility model discloses a microstructure one-way bending fatigue tester, wherein there are driving comb pairs on one side of a suspended vibrating mass and detection comb pairs on the other side;

We did a demonstration there with two vibrating objects with a spring, but yet the center of mass was moving with a constant velocity.

Requirements and design programmes of the widely used vibrating equipment have been introduced with emphasis on calculation of center of gravity and mass being vibrated of such equipment.
