Abstract
The vibration testing device includes a vibration generator having a rotary shaft rotatably supported on a support frame, and a clamp device using gas as working fluid. The clamp device has a first member and a second member, and is switchable by the working fluid between an unlock state in which relative rotation of the first member and the second member is allowed and a lock state in which the relative rotation is restricted. One of the first member or the second member is fixed to the support frame, and the other is fixed to the rotary shaft. The clamp device switches between the unlock state and the lock state to switch between allowing and restricting the rotation of the vibration generator relative to the support frame.
Claims7
A vibration testing device capable of changing a vibration direction of a vibration generator, the vibration testing device comprising:
- a support frame;
- a vibration generator having a rotary shaft rotatably supported on the support frame;
- and
- a clamp device using gas as working fluid, wherein
- the clamp device has a first member and a second member, and is configured to be switchable by the working fluid between an unlock state in which relative rotation of the first member and the second member is allowed and a lock state in which the relative rotation of the first member and the second member is restricted,
- either one of the first member or the second member is fixed to the support frame,
- the other one of the first member or the second member is fixed to the rotary shaft, and
- the clamp device switches between the unlock state and the lock state to switch between allowing and restricting rotation of the vibration generator relative to the support frame.
