Research Topics


To enhance the commericla viability of FEMRDYN, the computer code created and demonstrated in Phase I, an empirical validation project is proposed in Phase II of this SBIR. A series of component and system test rig modified to simulate normal and anomalous operation. Test results will be compared to the analytical predictions, and if necessary, adjustments will be made to the calculations to improve accuracy. In addition to the code validation activities, various auxiliary bearing configurations, such as gas, fould, and sleeve will be evaluated to investigate possible alternatives to traditional rolling element backup bearings. To insure the test objectives can be met, and to provide a clear path for commercializing the technology, DynaTech Engineering is teaming with AlliedSignal Engines to assist with auxiliary bearing designs, provide test facilities, and support data correlation. With the empirical verification, FEMRDYN will be an unrivaled design tool featuring an accurate and user friendly, multi-shaft system level predictive capability with advanced support models of magnetic bearings, gas (foil) bearings, and auxiliary rolling element bearings.
