- In the paper the influence of machining accuracy of mechanism links on their dynamic response is under investigation. As an example a of planar slider-crank mechanism is studied. The influence of different cross-section area within the assumed tolerance on the dynamic behaviour of mechanism’s connection rod is investigated. For vibration analysis of links the finite element method is used with Bernoulli-Euler beam elements. The calculation were conducted for nominal dimensions of the cross section of the crank and for the two cases for connecting rod: 1) for the maximal stiffness and 2) for the minimal stiffness obtained within the given tolerance. The results of analysis show that the changes in dynamic response for different cross-sectional area of mechanism links, within the assumed tolerance of machining, can be quite significant in the case of high-speed precise mechanisms and manipulators.
