Abstract(s)Spherical joints are commonly utilized in many real-world scenarios. From the more simplistic to the more complex perspectives, spherical joints might be modelled considering different cases. Thus, the aim of this study is to analyze and compare the influence of different spherical joint modelling approaches, namely the ideal, dry, lubricated, and bushing models, on the dynamic response of multibody systems. Initially, the kinematic and dynamic aspects of the spherical joint models are comprehensively reviewed. In this process, several approaches are explored and studied considering the normal, tangential, lubrication and bushing forces experienced by the multibody systems in such cases of spherical joints. The application of the spherical joint models in the dynamic modeling and simulation of the spatial four bar mechanism is investigated. From the results obtained, it can be stated that the choice of the spherical joint model can significantly affect the dynamic response of mechanical multibody systems.
