新型板坯连铸振动板簧系统的开发及应用

Study on New Type of Slab Casting Mold Oscillator Leaf Spring System and Its Application

应用大型商业有限元计算软件ANSYS,计算得到了板弹簧导向结晶器振动系统刚度系数在不同的变形条件下并非常数这一结论,从而引出板弹簧导向结晶器振动系统的非线性特征。进而通过对系统的模态分析以及瞬态分析计算,得到了系统在低阶激励频率下得到了高阶频率共振响应的结果,并通过将计算得到的水平位移-垂直位移图谱与测试得到的结果的比较,进一步验证了模型的合理性。介绍了由此设计的新型板坯连铸液压振动装置在莱芜钢厂的应用情况。

Using the commercial software ANSYS, obtained the result ：the stiffness coefficient of the leaf spring guide system is not strictly constant for various stroke deflection, thereby the nonlinearities of slab casting mold oscillator leaf spring guide were obtained . By performing the modality analysis and transient analysis subsequently, obtained the response of these higher harmonic at the excite of lower harmonic for the leaf spring guide system, and the reasonableness of the model was verified by comparing the picture of vertical displacement versus horizontal displacement ,which is obtained by calculation of this model ,and the picture of vertical displacement versus horizontal displacement from testing. And its application at Laiwu Steel was introduced.
