ETEK 3000 |
The ETEK 3000 is the world's foremost acoustic measurement instrument for friction materials. Using ultrasonic technology, the ETEK 3000 can measure all relevant elastic constants of friction materials as well as composites. Currently, ETEK elastic property data on new friction material formulations are required by all major US automobile manufacturers.
To speed the development of new friction material formulations and to design quiet systems, sophisticated models and simulations have been developed. The predictive capability of these models is dependent on accurate elastic property data, which can be responsible for both the generation and propagation of noise and vibration. NVH characteristics of vehicles become increasingly important factors in automobile development with advances in hybrid and electrical drivetrain components, which while generally decreasing the overall noise and harshness of a vehicle, allow for the noises and vibrations of other components, such as the braking system to become more noticeable and important. The ETEK measurement system is positioned as the leader in measuring relevant elastic property data for friction materials. ETEK systems have been sold to brake development laboratories of major US car manufacturers, first tier brake systems suppliers and major friction material manufacturers through the world. The ETEK 3000 measures all five independent elastic constants for:

The brake systems for new automobile models are often
specifically tailored to the individual needs of each model or
platform. Customer satisfaction is critically dependent on
braking free of noise, vibration and harshness.
Characterization of the brake components is needed for good NVH
characteristics.
