Estimation of seal bearing stiffness and damping parameters from experimental data.
A test rig was constructed to measure displacements and forces related to high performance rotors and their bearings and seals. An existing code for solution of boundary value problems in ordinary differential equations is used to estimate the stiffness and damping parameters for the rotor bearing seal. Test results indicate that the test rig and method give a more reliable and economical means of estimating these coefficients than other published means. (A)
