Ono Sokki Co., Ltd. (President: Yuji Okoshi), a manufacturer and distributor of electronic measuring instruments, will begin selling the "Loss Factor Calculation Tool OT-0450," which calculates the loss factor and Young's modulus of a vibration damping material using the frequency response function measured with the company's "Frequency Response Measurement Software OS-4100" *1.

The loss coefficient is one of the indicators used in the fields of mechanical vibration and polymer materials to show vibration damping performance. This tool calculates the loss coefficient and Young's modulus of a vibration damping material using the calculation formula described in JIS K7391 *2, based on the frequency response function of a multi-layer test specimen measured using the cantilever beam method or central excitation method with a strip-shaped test specimen.
Materials with a high loss coefficient are called vibration damping materials and are used by being attached to the surface of structures to reduce vibration and radiated noise. This tool helps to understand the vibration damping performance of materials and to use appropriate materials, contributing to improved quality and durability of various products such as automobiles, industrial machinery, and sporting goods.
*1 Software that operates with the DS-5000 Sound and Vibration Analysis System
*2 Japanese Industrial Standards
Features
- In addition to single-layer and double-layer test specimens, the system also supports sandwich-type test specimens, such as vibration-damping steel plates, and double-sided three-layer test specimens where vibration-damping materials are attached to both sides of the base material.
- Displaying multiple temperature conditions overlaid on a graph
- By using the OS-4100's pair-range function, which allows switching between two frequency ranges for measurement, measurement time can be shortened.
Target Market
- Chemical, metal, and textile manufacturers developing new materials.
- Automotive, automotive parts, machinery, home appliance, and sporting goods manufacturers, among others, that develop products affected by vibration.
