Abstract:

Combined with the theory of dry friction and the basic theory of vibration, a dynamic model of rotary dry friction vibration isolation system was established.Utilized the geometrical and mechanical principle, the main body of the design of the rotary stiffness was analyzed by MATLAB software.In addition, the rotary damper stiffness with base displacement and section thickness variation for rotary structure was also considered.analyzes the main body of the design of the rotary stiffness analysis using MATLAB software, the rotary damper stiffness with base displacement, section thickness variation for rotary structure.In view of the characteristics of the rotary structure, the energy dissipation model of dry friction damping base plate and rotary structure was designed creatively.
