Spring Mass Vibration System | Vibrano X - 09
Product Overview
The Spring Mass Vibration System - Vibrano X - 09 is a bench top unit for analyzing oscillations of a spring mass system. It features a helical tension spring with a frequency range of 2...7Hz, running on a precision bearing cradle along vertical guides. This Spring Mass Vibration System supports free and damped oscillation testing using an oil damper with a damper constant of approx. 15...300Ns/m. Cradle motion is recorded on a driven drum recorder using 100mm graph paper, with calibrated weights included to vary oscillating mass.

Construction and Design
The Spring Mass Vibration System - Vibrano X - 09 is built on a sturdy bench top base that secures two vertical guides in a vertical plane. A top horizontal bracket keeps the bars at a near constant width. A cradle runs up and down the bars on precision bearings, which minimize friction.
The cradle attaches to one end of a helical tension spring of known wire diameter, free length, and spring rate. At the other end of the spring, an adjustable screw mechanism sets the spring's starting position. The cradle carries its own self weight, and calibrated weights can be added to vary the oscillating mass.
The cradle's vertical motion is transferred to a rotating drum recorder mounted with paper. Oscillations of the cradle can be free or damped, with the damped option requiring the damper to be attached to the cradle. This Spring Mass Vibration System uses a low friction, bearing based cradle assembly to ensure accurate oscillation measurement.

Frequently Asked Questions
Q: What does the Spring Mass Vibration System - Vibrano X - 09 analyze?
A: It analyzes the oscillations of a spring mass system, including spring stiffness, natural frequency, and damping behavior.
Q: What is the spring frequency range?
A: The spring frequency range is 2...7Hz.
Q: How is the oscillating mass varied?
A: The oscillating mass is varied by adding calibrated weights to the cradle, which has a self weight of approx. 1.25kg, plus 5x 2kg additional weights.
Q: How does the damping system work?
A: Damping is created using an oil damper with a freely adjustable damper constant of approx. 15...300Ns/m, using hydraulic oil as the damping medium. The damper must be attached to the cradle for damped oscillation testing.
Q: How are oscillations recorded?
A: Cradle motion is transferred to a driven drum recorder with a synchronous motor drive, running at a paper speed of 20mm/s on 100mm graph paper.
