Abstract

This paper deals with the jerk and jounce relevance for the kinematic performance of long-dwell mechanisms of linkage type, which are used in automatic machines to generate intermittent motions with a suitable holding position of the output-member. According to the dead-points superposition method, the duration of this holding position with respect to the machine time cycle, can be increased by connecting in series several planar mechanisms in dead-point configuration, such as four-bar linkages of crank-rocker type, slidercrank mechanisms and Cardan’s mechanisms. The jerk and jounce analysis of long-dwell mechanisms is proposed in this paper with the aid of significant examples, along with numerical and graphical results, since the typical kinematic analysis up to accelerations is not enough to understand the kinematic performances of long-dwell mechanisms and higher-order time derivatives are required.
