This work focuses on analyzing the dynamical behavior of a mechanical system consisting of a double spatial pendulum in contact with a movable obstacle. The pendulum’s ability to move in space is achieved by the use of special Cardan–Hook joints as the links of the pendulum. The mechanical system is equipped with a special movable obstacle, i.e. a rotating circular plate situated below the pendulum, which limits the space of admissible positions. A significant part of this work is devoted to the modeling of the contact between the pendulum and the obstacle. In this regard, a special class of reduced models is derived with the resultant friction force and moment acting on the finite size of the contact area along with a compliant model of impact based on the Hertz stiffness. Finally, the effective model suitable for fast and realistic numerical simulations is obtained. The contact model is tested numerically and the effect of its parameters on the system bifurcation dynamics is investigated.

Reasonable simplification of finite element modeling of complex mechanical systems can reduce the amount of elements and nodes. The solution efficiency is improved in this way, which is of great economic significance in the practical engineering problem. Based on the modeling and simulation of a Conveyor System between Roving Frame and Spine Frame in automated textile production line, this paper investigates and proves the effectiveness of simplification of the complex mechanical system in the dominant finite element software – ANSYS. Results of static analysis of the simplified model agree well with the actual data, proving that the simplified solid-beam element model of the Conveyor System is reasonable. The results lay the foundation for the subsequent kinetic analysis and optimal design of complex mechanical system.
