Depending on their applications, foil bearings need a sequence of unique tests before applying them to final systems. From years of onsite test support of various high speed turbomachinery, our team offers the best solutions from a simple component level test to full scale rig/actual system tests
Typical rotordynamic analyses using linear stiffness and damping coefficients of the foil bearings do not provide accurate prediction of rotordynamic behavior of foil bearing-supported rotors. Our team offers state-of the art non-linear transient rotordynamic analyses along with dynamic reaction forces from the foil bearings. The method is a little more time-consuming than traditional methods, however, it provides unparalleled accuracy.
Thermal management of foil bearings are equally important. Our team developed the most advanced secondary flow analysis software which can predict pressure and temperature of entire secondary cooling air flow passages including foil bearing static/dynamic performance within the secondary flow passage. Several companies benefited our engineering service to optimize thermal management of the bearings minimizing the cooling air flow rate.
