Sound and Vibration Analysis System

O-Solution DS-5000

The loss coefficient and Young's modulus (longitudinal elastic modulus) of the damping material itself are calculated from the measurement results of the multi-layered test specimen using the formula described in JIS K7391.

The loss coefficient is one of the indicators used in the fields of mechanical vibration and polymer materials to show vibration damping performance. Damping materials with a large loss coefficient are used by being attached to the surface of structures for the purpose of reducing vibration and radiated noise. This tool calculates the loss coefficient and Young's modulus of the damping material itself from the frequency response function of a multi-layered test piece (a test piece with damping material attached to a base material) measured with the frequency response measurement software OS-4100, thereby clarifying the vibration damping performance of the damping material.

Case Studies

Acoustic analysis of a motor using a sound level meter

The sound generated by a motor can be recorded with a sound level meter and analyzed in detail with O-Solution. By importing the data (wav format) recorded with the sound level meter into O-Solution, you can play back the sound and perform frequency and octave analysis on your PC.

Automated measurement and analysis using external control

Measuring repeated data and analyzing large amounts of data is extremely time-consuming and laborious. O-Solution provides an external control library (O-Step API). By communicating via TCP/IP between O-Solution and an app (user-original software) created using the O-Step API, O-Solution can be controlled. This makes it possible to automate repetitive tasks.

*The DS-5000 series (hardware) is required for measurement work (data acquisition).
If you want to perform analyses other than FFT analysis, you will need a separate option.
