| Abstract: | Based on the theory of multi-body dynamics, the dynamic model of the spring operating mechanism is developed. The dynamic property during the switching of the spring operating mechanism is analyzed and the rule of the kinematics and dynamics is revealed. Then the virtual prototype of the spring operating mechanism is set up based on the ADAMS, which can fulfill the dynamic simulation and the research of the dynamic property. The numerical calculation and dynamic simulation analysis of the spring operating mechanism and the verification of the result of the two methods multually provide theoretical basis for the dynamic optimum design and reliability design of the spring operating mechanism. |
