The Vibration of Spiral Spring Apparatus - Vibrano X - 03 studies the vibration behavior of a spiral spring rotating mass system. It features a cold rolled steel spiral spring with stiffness of c = 238Nmm approximately, clamped between a ball bearing mounted shaft and a fixed bracket. This Vibration of Spiral Spring Apparatus uses two adjustable sliding weights on diametrically opposite levers to vary moment of inertia. Rotation angle is read on a 0...360° scale disc with 1° resolution. The unit is wall mounted and includes a stopwatch for timing measurements.

Construction and Design
The Vibration of Spiral Spring Apparatus - Vibrano X - 03 is built around a spiral spring made of cold rolled steel. The spring is clamped between a ball bearing mounted shaft and a fixed bracket. Two levers are fitted to the shaft, positioned diametrically opposite each other. Two sliding weights made of metal are mounted on the levers. These weights can be securely fixed in position using clamping screws, forming a rotating mass with adjustable moment of inertia. The system is displaced by hand to initiate vibration. The angle of rotation is read off a 1° scale disc attached to the shaft. This Vibration of Spiral Spring Apparatus is designed for wall mounting.
Scope of Delivery
Q: What does the Vibration of Spiral Spring Apparatus - Vibrano X - 03 measure?
A: It measures the stiffness of a spiral spring and the natural frequency of a spiral spring-rotating mass system.
Q: What material is the spiral spring made of?
A: The spiral spring is made of cold rolled steel.
Q: How is the angle of rotation measured?
A: The angle of rotation is read off a 1° scale disc attached to the shaft, with a measuring range of 0...360°.
Q: How is the moment of inertia adjusted?
A: The moment of inertia is adjusted by sliding the metal weights on the levers and securing them with clamping screws at different arm radii, ranging from 36 to 150mm.
Q: How is this unit installed?
A: The unit is intended for wall mounting.
