The rotor dynamics package “ROTLAT V6.1” uses a finite-element based formulation for performing damped and undamped lateral natural frequencies, mode shapes, stability, unbalance response, and time-transient response of rotating systems. ROTLAT has its own user interface and integrates four modules: ROSTAB, ROTORMAP, ROSYNC, and RORESP. The user interface controls the modules to provide a complete lateral vibration analysis environment.
ROTLAT permits user selectable output units between CPM or Hz, in accordance with the user’s preference, or the industry standard format, which can be set simply by checking a box in the options form. Also damping parameter (ratio or log. dec.) can be selected. Full user control for generating critical speed maps with or without speed or gyroscopic effects are provided. Additionally, forces (excitations) such as unbalance considered in synchronous response analysis can be combined with gravitational body forces and any externally applied forces and moments in the time transient response simulations.
ROTLAT results include:
