Examination of Some Assumptions Practised in Vehicle Vibration Isolation Prediction and Design 951272
Some common assumptions used in simplifying vehicle NVH prediction and design, in conjunction with isolators and mounts, are examined with the aim of offering qualitative improvements. It is often assumed that only the translational degrees of freedom are sufficient for a detailed structural analysis. Errors introduced by this simplification are quantified for some illustrative and simple examples concerning isolators, coupled analyses and transfer path analyses. It is suggested that a complete measurement procedure can alleviate the need for assuming beforehand that the rotational degrees of freedom are not essential. Once obtained they can be disregarded if demonstrated unnecessary.
