The Exploration on Principal Vibration Mode of the Multi-Freedom System
In calculation of structural dynamics, determining principal mode of multi-freedom system structure often is an issues concerned by the engineering and technical personnel. The supperposition method is one way which is usually widely used by engineering and technical personnel, but this method has its limitations. This paper introduces common calculation methods of the structure of principal mode, and the amendment solution of the supperposition method is deduced. This method is accurate through checking of the examples.
