Vibration of Spiral Spring Apparatus | Vibrano X – 03
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.
The Vibration of Spiral Spring Apparatus – Vibrano X – 03 is designed to study the vibration behavior of a spiral spring rotating mass system. A spiral spring made of cold rolled steel is clamped between a ball bearing mounted shaft and a fixed bracket. This Vibration of Spiral Spring Apparatus is intended for wall mounting and enables determination of spring stiffness and natural frequency.
Product Overview
A spiral spring made of cold rolled steel is clamped between a ball bearing mounted shaft and a fixed bracket. Two levers are fitted to the shaft diametrically opposite each other. Two sliding weights of metal on the levers can be securely fixed in position using clamping screws. These form the rotating mass with an adjustable moment of inertia.
The system is displaced by hand. The angle of rotation is read off on a 1° scale disc that is also attached to the shaft. The unit is intended for wall mounting.
This Vibration of Spiral Spring Apparatus determines the periodic time for a spiral spring attached to a shaft of vibration moment of inertia. It features an effective torque of 30mm. A stop watch is included, along with all necessary accessories with list and instruction language.

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
- 1 Experimental module
- 1 Set of weight
- 1 Stopwatch
- 1 Instruction manual
