Probabilistic behaviour of joints on joint forces in mechanismsHarl, Boštjan (Avtor) Gubeljak, Nenad (Avtor) Kegl, Marko (Avtor) joint forceskinematic chainmathematical programmingstochastic modelThis paper discusses the influence of the clearance in joints on the joint reaction forces in mechanisms. By using mathematical programming, the optimal parameters of kinematic chains can be efficiently obtained by using the deterministic approach. However, the situation becomes more sophisticated if random effects of tolerances of the arm lengths and the random pin positions have to be considered. In this work the influence of clearances on joint forces is calculated by using the Taylor approximation and the Monte Carlo method. The implementation of the model is illustrated with two examples. The first example considers a closed loop chain, representing a four-bar mechanism being an actual part of a hydraulic support, employed in mining industry. The second example considers joint reaction forces of car wiper mechanism.20152017-07-12 09:36:43Znanstveno delo66825ISSN: 1330-3651UDK: 620.172.2OceCobissID: 15346181COBISS_ID: 18547734DOI: 10.17559/TV-20131023220214ISSN pri članku: 1330-3651NUK URN: URN:SI:UM:DK:K5L96OWNsl
