A method for determination

In kinematic synthesis and analysis of planar mechanisms the designer must define a geometry and set of motions for a design task. This paper will focus on how to determine the forces or torques acting on the planar mechanism by numerical method when acceleration and dynamic properties of the linkage are known.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).
