Title: The application of transfer matrices in the dynamic analysis of planar elastic mechanisms
Authors: Lindenberg, Richard Kent
Committee Members: Kitis, Levent
Summary: Transfer matrices are used in the dynamic analysis of planar elastic mechanisms. Mechanism motion is discretized by dividing the motion into a finite number of intervals over which the mechanism is considered to be an instantaneous structure with constant geometry. Transfer matrix methods are then used to calculate the natural frequencies and corresponding mode shapes of the instantaneous structure. A transfer matrix relating the continuous, non-zero components of the state vector across a pin joint is developed. An elastic four bar mechanism and a crank slider mechanism with a rigid crank and elastic connecting rod are analyzed using lumped mass models. Results of the four bar mechanism analysis show good correlation with results obtained by others using finite element methods.
