Abstract
A PC-based software tool has been developed which optimizes the placement of sensors for vibration monitoring. This tool, called Blade-OPS, incorporates a methodology that allows the instrumentation design engineer to make tradeoffs between mode identification, mode visibility, data integrity and geometry. It uses a genetic algorithm optimization approach that simulates the natural selection process to develop an optimum design. For the blade considered here, several instrumentation configurations were selected which yield an improved fitness rating relative to the baseline sensor locations which were selected without using rigorous optimization approach. Application of this capability is not limited to turbine engine components, but will be useful for any dynamic test where instrumentation is limited.
