As the rotational velocity of any rotating object increases, its level of vibration often passes through a maximum at what is called a critical speed. This is commonly excited by unbalance of the rotating structure. If the amplitude of vibration at these critical speeds is excessive, catastrophic failure can occur. Turbomachinery also can develop instabilities which are related to the internal makeup of turbomachinery, and which can also cause catastrophic failure. Engineers who design large rotors are challenged to design safe rotating machinery using physical prototypes and tests alone.
MSC Nastran Rotor Dynamics provides a highly accurate and reliable rotor dynamics solution that enables engineers to simulate the behavior of rotating machinery. Using MSC Nastran Rotor Dynamics, engineers are able to predict critical speed and evaluate the effects of instabilities on virtual prototypes, saving time and money while improving safety.
