COMPUTATIONAL DYNAMICS OF HELICAL FLEXIBLE COUPLING WITH TRANSITORY CONTINUOUS REGIME

Abstract

Dynamic behaviour of flexible couplings within the vibratory equipments frames the global area of this study. This paper briefly presents some critical results regarding the helical-type coupling dynamics taking into account a few theoretical assessments in terms of linear and nonlinear approaches of driving chain elements. Simulated behaviors denote that many of the reported observation regarding the serviceable dynamic distortions are correctly, and impose a set of additional instrumental tests in order to obtain a good accuracy for mathematical models. A both simplified and expanded computational model has used for numerical computations. The main hypothesis of this analysis supposes the continuous changing of dynamic characteristics, and the additional dynamic loadings due to internal elements of coupling device.
