Acoustics and vibrations

Acoustics

• Acoustic harmonisation of vehicle systems in the vehicle or under laboratory conditions (steering, stabiliser control, gearboxes, electric, pneumatic and hydraulic drives, powertrain, etc.)
• Actual status evaluation, improvement and optimisation, recommendations for packaging, pre-series and series releases
• Set-up and operation of test benches for the development of systems regarding fluid-borne and structure-borne noise and assessment
• Advice on design, simulation and prototype construction in the field of acoustics
• Coordination and/ or support of development work by OEMs and suppliers
• Support in the drafting of specifications and creation of processes

Vibration behaviour and dynamic loads

• Measuring of operational vibrations (dynamic loads, dynamic responses, structure-borne and fluid-borne noise)
• Analysis and assessment according to specified standards as a basis for component testing and for the development of test procedures
• Analysis and assessment of ride comfort, rough road analyses
• Mobile measurements in vehicle or on test bench, also with ignited engine
• Sensor applications, in particular DMS applications for determining loads on ignited or rotating parts
• Calibration of test parts (bending, torsion, rotating bending, tension, internal pressure etc.)
• Determination of static and dynamic properties of components, body in white and complete vehicle
• Identification of structural changes
