Modal and Static Structural Analysis of Exhaust Collector Box for Compressor test facility

Shankar Gouda, Praveen M P

Collector box is one of the influencing factors for stability of operation of test compressor. Collector box in compressor test facility is used to collect the high pressure exhaust air from the exit of the test compressor. It is subjected to flow fluctuation during compressor testing, making it vulnerable for structural related problems like high vibration. The results indicate that Compressor-Collector box interactions may strongly affect compressor performance unless the lowest resonant frequency of the collector box is much higher than the natural frequency. An analytical and experimental investigation of the static and dynamic behaviour of exhaust Collector box is described, including the effects of compressor-collector box dynamics.
