LMS Samtech Samcef Rotors Rotor dynamics simulation of global rotating systems including bearings, gears and linking devices LMS Samtech Samcef Rotors is a rotor dynamics simulation solution dedicated to the dynamic analysis of fast rotating machines such as jet engines, turbo machines, gas and steam turbines, pumps, propellers and fans. Based on finite element theory, the rotor dynamics software enables the computation of critical speeds and responses to excitations in the frequency and time domains of fast rotating systems. The rotating systems can also include nonmoving parts (such as stators and casings) and linking devices (such as bearings and gears). LMS Samcef Rotors addresses the complex challenge of rotor dynamics analysis, providing a solution for rotor dynamics specialists and engineers focused on global dynamics of rotating machines. Delivered with LMS Samcef Field, the software includes all classical finite element analysis features as well as a driver dedicated to rotor dynamics analysis. Backed by 30 years of experience in this field, the LMS Samcef Rotors solution is the best tool for accurate simulation of high speed rotating machine behavior, rotor dynamics analysis and rotating machine vibration control.
