The necessity and importance of the vibration analysis at the design stage increase further more under a recent technological trend such as the limit design for the energy saving and resource saving. Therefore, high-accuracy analysis is required for a large-scale degree of freedom model similar to an actual machine. Then, based on a dimensional reduction method by using the constrained modes, a practical system of vibration analysis applicable to various nonlinearities was developed.
