Elastic Linkage Passive Vibration Control Of Dynamic Simulation And Analysis

In this thesis, the theory of damping and the method of Kineto-ElastoDynamics(KED) is applied toconduct the theoretical analysis and numerical calculation on the kinetic and dynamic properties of elasticlinkape mechanism under the condition of complex damping.First, based on the Type Transformation theory and the Kineto-ElastoDynamics theory the dynamicmodel of the elastic linkage mechanism is set up.Second, based on a comprehensive stody of existing papers, corrected system dgnamic model underdifferent damping is put forward. The model, for the first time, take structural hysteresis damping andkenamatic pair visco damping into account. Thus, a more accurate dynamic model is established.Third, corrected mode superposition principle and state space method are combined with Householdmethod to solve the dynamic dtherential equations under different damping conditions.At Last, according the analysis model and numerical method mentioned above, the digital simulationon the responses of this system is carried out The response curves of all generalized coordinates areobtained, and the effect of vibration damping is analyzed.
