Mecanum - Noise Control Services

Quasi-static mechanical analyzer (QMA)

The Mecanum's quasi-static mechanical analyzer (QMA) is specifically design to obtain a reliable measurement of the elastic properties of a wide range of materials used for noise control. It uses a novel compression method designed by Université de Sherbrooke using polynomial relations to simultaneously measure the three elastic properties. It has been validated against other mechanical analysis methods and software simulations.

Material properties

Young modulus E; Poisson ratio ν; Damping loss factor η

Applications

The QMA has been a proven value to the world’s leading materials suppliers to both the automotive and aircraft industry. It is used for quality control in the manufacturing process of materials, R&D applications, and to feed acoustical prediction software. The elastic properties measured with the QMA are compatible with the Biot’s poroelasticity equations and Biot-based programs: Nova™, VA One™, and MSC Actran™

Features

QMA system includes the QMA hardware, the USB DAQ system, software QMA-X™, and a calibration spring and its chart to validate the test procedure. The QMA-X™ software fully controls the measurement and calculate the statistics on the elastic properties. The frequency range is typically 10-100 Hz. The QMA works with disc shaped samples as those used for Mecanum's impedance tubes, porosity meter and static airflow resistivity meter
