Abstract


Suspending Link Organization law of motion and force combines paper uses vector analysis and theory , and a pendulum ring mechanism dynamics simulation using the dynamic simulation software ADAMS and finite element analysis software Ansys and stress analysis, the main significance of this study is to provide guidance for the the pendulum ring institutional structure design and improved . This thesis is mainly done the following work : (1 ) pendulum ring mechanism motion analysis , derivation of the equations of motion of the organization , draw a pendulum motion parameters of the ring mechanism Suspending Link Organization program designed to provide a key technical parameters ; analysis of each component of the force , derived kinetic equation and the mechanical efficiency formula provides a theoretical basis for the pendulum ring structure design agencies and improved . ( 2 ) combined with three-dimensional modeling software UG establish a geometric model of the institution , the institution using ADAMS software movement and dynamics simulation , the simulation results and theoretical calculation results and found that the two results agree with each other to verify the simulation model , the simulation method and the correctness of the theory and credibility . While dynamics simulation results provide important data for finite element analysis in the force of the load pendulum ring mechanism key member . ( 3 ) the use of Ansys finite element analysis software to the institution of a finite element analysis , calculation results show that the design of the spindle shaft diameter change at install swing ring there is a certain amount of stress concentration , and to take appropriate increase fillet to reduce stress concentrated ; spindle stress distribution in the main installation pendulum ring journal surface , so the surface should be finished at the same time improve the surface quality factor and appropriate to increase the shaft diameter . By finite element analysis , the structure of the institution to meet the requirements. In short, this article by theoretical analysis and simulation analysis , has been wobble institutions important to the equations of motion and kinetic equations wobble agencies improve the design and further transmission characteristics analysis and modal analysis laid the foundation .
