About the project
In this project you will use modelling and experimental methods to build an understanding of how vibration and shock mount design can influence machine bearing life.
In both defence and civilian applications, machines are often installed on soft isolation mounts to reduce transmission of self-generated vibration to the supporting structure. These mounts must also be sufficiently stiff to support the weight of the machine. Forces on bearings and other machine elements, and hence their wear, are estimated based on the assumption that gravitational forces are equally distributed which is not always guaranteed, particularly in marine environments where significant motion of the supporting structure occurs. This poses a significant challenge to the Condition Based monitoring (CBM) industry since current installation standards are not applicable. Premature bearing wear can result, causing costly and disruptive unscheduled maintenance.
This project will investigate the effect of mounting arrangements on the degradation of bearings for machines with variable orientation.
The main objectives are:
- to develop theoretical and numerical models to predict the influence of isolation mounts on bearing life
- to undertake practical measurements on running machines to validate modelling activities
- to identify installation principles for low bearing wear
- to embody recommendations for best practice in new installation guidance.
