Elastic Slider-Crank Mechanism. a Study of the Intrinsic Configuration-Dependent Modal Properties
In recent years, an ever-increasing demand has been placed on manufacturing for increased productivity, requiring machines to run faster, quieter and with greater precision. This has necessitated that the elastodynamic behavior of mechanisms be carefully evaluated if better machinery must be designed. Although numerous works have been presented for computing the response of mechanisms containing elements characterized by distributed mass and elasticity, very little has been revealed about their modal properties. This paper addresses the modeling of planar slider-crank mechanisms, a popular class of mechanisms, for geometrically nonlinear, elastodynamic response. A modal analysis is performed for varying positions of the crank, and configuration-dependent natural frequencies and mode shapes are presented as functions of the crank position. The results, which includes a study of the effects of some design parameters on these modal properties, should provide new and valuable insights to the designer and researcher alike. These intrinsic modal properties will directly affect the parametric vibrational response and stability characteristics of elastic slider-crank mechanisms.
