摘　　要：结晶器液压振动装置是提升连铸装备水平以提高实际生产应用能力并保证铸坯质量的关键设备之一。针对某大型工程技术有限公司设计的结晶器液压振动装置,采用系统计算机辅助工程(CAE)技术对整体设备建立了分析模型,并进行了结构动态行为仿真。通过对结晶器液压振动装置的固有频率分析和应力动态响应分析可知,整体结构系统的第一阶频率远高于最大激励频率,不会出现共振现象;所有激励频率下结构完全满足考虑了动应力的强度要求。Crystallizer hydraulic vibration device iz one of the key equipments which can improve the ability of practical production and application, and ensure the quality of the casting blank, through promoting continuous casting equipment. Aiming at crystallizer hydraulic vibration device designed by a large Engineering and Research Inc., Ltd, systematic computer aided engineering （CAE） technique was .adopted to create its analysis model for the whole equipment, on which simulation of the structural dynamic behavior was conducted. Through natural frequency and stress dynamic response analysis on the crystallizer hydraulic vibration device, it was found that fundamental first frequency of the whole structure was much higher than the maximum excitation frequency and resonance phenomenon should not occur. The structural strength requirements including the dynamic stress can be fully met under all excitation frequencies.
