Center point
Mecanum’s Center Point measures the Young’s modulus, the shear modulus and the structural damping factor of elastic and viscoelastic materials. The method is based on the measurement of the entry mobility of a free-free beam excited in its center.
Why choose Mecanum’s Center Point?
Follows ISO 16940, SAE J3130 and JIS G 0602 standards
Choosing a center point system compliant with ISO and other standards ensures accuracy, reliability, and global acceptance. It offers precise measurements, compatibility with other equipment, regulatory compliance, and long-term value, making it a prudent choice for industries and research where damping factor, Young’s modulus or shear modulus are crucial.
Made for automotive industry and building construction
Damping stands out as a highly effective solution for minimizing noise and vibrations, finding widespread application across industries, particularly in transportation. It plays a crucial role in reducing structural noise and addressing issues like squeaks and rattles in vehicles.
By damping vibrations at resonant frequencies, it significantly enhances the longevity of structures. In building construction, damping is instrumental in improving panel insulation and reducing noise from plumbing and ventilation systems.
Masters temperature and humidity with climatic chamber
Our center point test bench facilitates precise measurements across various temperature and frequency spectrums, empowering engineers with comprehensive data to evaluate the compatibility of damping solutions with their intended applications.
Damping materials typically exhibit viscoelastic behavior, meaning they possess both elastic (spring-like) and viscous (fluid-like) properties. These characteristics make them responsive to changes in temperature and frequency. Consequently, engineers must carefully select the appropriate material to suit specific application requirements.
Improves viscoelastic properties representation
Viscoelastic mechanical properties are highly dependent on both temperature and frequency. Traditionally, this complex behavior is modeled using the Williams-Landel-Ferry (WLF) equations and represented graphically by nomograms. However, nomograms can be difficult to interpret due to their complexity.
A more intuitive approach is to visualize these properties with 3D graphs. By plotting temperature, frequency, and key mechanical properties Young’s modulus or shear modulus and damping on a 3D surface, we get an immediate, comprehensive view of how materials behave under varying conditions.
