General method for kineto- elastodynamic analysis and synthesis of mechanisms

The initial phases in the development of a general method of kineto- elastodynamic analysis and synthesis based on the flexibility approach of structural analysis, which may be applied to any planar or spatial mechanism. Dynamic error is investigated due to flexural, longitudinal, and torsional element strain, and system inertia fluctuations; the treatment of Coulomb and viscous friction is indicated. K ineto- Elastodynamic Stretch Rotation Operators are derived which will rotate and stretch both planar and spatial link vectors reflecting rigid bodymotion plus elastic deformations of the link. A numerical example is presented to demonstrate the elastodynamic analysis technique.
