Studying the dynamics of cam mechanisms is crucial to ensure reliable, efficient and fast machines. RecurDyn offers the ability to study complex cam mechanisms to calculate positions, velocities and accelerations, to evaluate possible interferences, and to obtain the loads acting on each component.
In this example, a gluer machine was studied using RecurDyn: the cam was represented using a 2D contact; the bodies were initially considered to be rigid, after which they were also modelled as Full Flex bodies to evaluate the influence of the flexibilities on the machine’s performance.
The model provided useful information for optimizing the cam’s profile, for evaluating the overall motion of the mechanism, and for obtaining the loads that were later used to perform structural verifications.
This article proposes the use of computational fluid dynamics (CFD) to address these complexities.
