Abstract : The classical approach for the analysis of linkages has been to assume rigid elements during operation. As the operational speeds of mechanisms increase, this assumption creates larger errors in the analysis. Thus a better model of a machine that considers elastic deformations will aid in more efficient design as well as provide improved accuracy and performance. The thesis presents a simulation for the dynamic response of an elastic link model with three clearances. The simulation has been developed for an automobile, cam actuated valve train. The computer program is coded in FORTRAN 4, for an IBM-360 computer and is included as a portion of this work. The capability to visually observe the dynamic action of the model is included by a graphic display routine. (Author)
