Dynamics Simulation on the Oscillation Device of Continuous Casting Crystallizer

以无干扰复式结晶器板簧振动装置为研究对象,根据对连铸结晶器振动装置结构的研究,使用静力学中的常用方法将结晶器振动装置分为两部分,分别作独立的受力分析,同时采用虚位移原理与达朗贝尔原理分析振动结构,计算了液压缸端的负载。从实际生产需要出发,采用ADAMS虚拟样机软件对结晶器振动装置—无干扰式全板簧结晶器振动装置的动力学状态进行分析,得到液压伺服系统结晶器振动端与伺服油缸激振端之间的振动参数关系,为液压系统的设计提供理论基础。

The full-leaf spring crystallizer oscillation device without interference is researched. According to the research on the construction of oscillation device of continuous casting crystallizer, the oscillation device is divided into two parts by using the common method in statics, both analyzed separately. The principle of virtual displacement and D＇A lembert principle are applied to the analysis on vibration structure, thus the load on the hydraulic cylinder is calculated. In order to meet the requirement of actual production, the dynamic analysis of oscillation device of crystallizer which is full-leaf spring crystallizer oscillation device without interference is conducted by virtual prototype software ADAMS. As a result, the vibration parameters＇ relationship between crystallizer vibration end of hydraulic servo system and the excitation end of servo-cylinder is obtained, which provides theoretical basis for the design of hydraulic system.
