We use a grinding machine spindle as an example to consider a hybrid (numerical and analytical) method of simulating a rotor with a rigid shaft. The paper describes a spatial dynamic model of the rotor constructed via this method that takes into account support stiffness asymmetry. We show that introducing support stiffness asymmetry allows the spatial simulation to explain a number of physical phenomena, including spectrum frequency splitting, which are fundamentally impossible to explain when using flat axially symmetric models.
