NVH - Noise, Vibration and Harshness

NVH performance depends on the characteristics of rubber bushes and mounts. Ride and handling depends on suspension bushes as well as springs and dampers. MERL provides materials development and evaluation testing, component testing and design analysis for these critical components.


Materials development

Development of rubber compounds with e.g. improved ageing resistance, higher temperature performance, etc.

Materials evaluation
Elastic, visco-elastic, crack growth (fatigue) behaviour
Ageing and chemical resistance
High/low temperature limits

Component testing
Static and dynamic characterisation of vibration control components, e.g. engine mounts, rubber bushes
Fatigue testing of vibration control components in single or multi-axis
Ageing and chemical resistance of vibration control components

Design analysis + FEA
Design of vibration control components
Behaviour prediction of vibration control components
Prediction of dynamic stiffness and damping
Prediction of durability/fatigue life
Long term service assessment
