The mould is one of the key devices of continuous casting machine,and the yield and quality of continuous casting mainly depend on the vibration of mould.Therefor,it is quite significant to study mould vibration system.The development of mould vibration technology and the mould non-sine wave vibration technology at home and broad are introduced in the dissertation.Combined with short lever electro-hydraulic mould vibration system,the whole research on dynamic characteristics of mould hydraulic non-sine vibration system and kinematics and dynamics characteristics of mould four-link vibration mechine are based on both the acquirment of mould non-sine vibration system and analysis of mould non-sine vibration regularity. This study puts emphasis upon several parts:1) On basis of knowing about mould hydraulic vibration system and modeling methodologies and simulation and optimization of draulic servo system,study the structure of mould hydraulic vibration and build mathematic model.2) According to the mould hydraulic vibration mathematics model,analyzed the dynamic characteristic of the mould hydraulic vibration system with the MATLAB/Simulink module,figured out the simulation curve of main controlled variable.Effect of main parameters to the system performances is analyzed.3) Based on the 3D prototyping model of mould four-link vibration mechine with Pro/E and ADAMS and dynamic simulation ,study the kinematics and dynamics characteristics of mechine with different frequencies and amplitedes.Results of dynamic characteristic analysis will provide theoretic data for design and improvement to the continuous caster. It will provide theoretic support for the oscillating mechanism using high frequency and short stroke oscillation parameters.
