Abstract
This paper details the modification of a commercial data acquisition system for use in a geotech-nical centrifuge. As with many ‘off-the-shelf’ components put into service within the harsh high stress centri-fuge environment, they are not originally conceived to operate under these extreme conditions and thus it is not uncommon for high failure rates to occur in standard hardware items. In many cases successful modification can be implemented to strengthen standard components to enhance their robustness and operation. In this re-spect, this paper reports on difficulties experienced in the operation of a National Instruments PXI chassis sys-tem and its failure in the high gravity environment. Specific problems identified relate to fragility of the cooling fan systems that generate fault conditions that trigger auto shut down sequence of the chassis. A bespoke solution is developed and documented that has been successfully implemented to circumnavigate and mitigate fan failures.
