Material faults, assembly errors or functional problems lead to characteristic changes in the sound and vibration behavior. Acoustic test systems can be used to detect functional errors, assembly errors and acoustic quality problems. Our fully automated acoustic test systems are used for 100% end-of-line testing of driven components and assemblies such as engines, electrical drives, pumps, vents, adjusters, white goods and loudspeaker systems.
Depending on the test item and test environment different sensors such as accelerometers, microphones, laser sensors and current probes can be used for objective analysis of functional noises and vibrations in real-time. Our BSR SUITE test system enables the analysis and objective evaluation of sound and vibration, force, torque, current, RPM, temperature and other parameters on up to 64 measurement channels. Freely programmable error specific metrics are used to detect and differentiate typical faults and to provide rework instructions directly at the production line. Objective test results can be transferred to statistical quality control systems.
Safety and performance tests can be combined with functional tests and acoustic quality tests in a single test bench. Acoustic test systems are also used in endurance test benches in development and quality departments.
MB Dynamics delivers turnkey acoustic test systems. We support our customers from the development of suitable test criteria, objective metrics and thresholds to the integration of acoustic test systems into existing or new test benches, training for users and system supervisors, calibration and online support.
