Topology Analysis of Vibrating Compacting System with the Hysteretic Characteristics of Materials Considered

摘要

Materials present elastic-plastic deformation under cyclical loading because of the influence of vibration friction, and restoring force and the displacement show hysteretic characteristics in compacting mechanism and materials system. To further study nonlinear dynamics of the vibrating compacting system, system model with symmetric hysteretic curve was established in this paper, and was verified by experiment. Bifurcation and chaos motion were studied in nonlinear vibrating compacting system by the combination of qualitative theory and numerical solution, and analysis results show that vibration have piecewise and singular characteristics in vibrating compacting system, and hysteretic loop parameters show significant influence on system and large effect on nonlinear dynamics of system.
