| 摘 要： | 采用有限元法,对上海宝钢集团公司1580车间SP定宽机进行了侧压冲击力的有限元模拟,给出板坯侧压过程冲击载荷的变化规律,计算了板坯的应力变化与金属三维流动状态,并分析了板坯缺陷形成的原因。通过对 SP定宽机侧压过程的动态测试,分析了侧压过程中模块加速度的变化,给出冲击力的试验结果,并对有限元模拟结果进行验证。由模块的动态特性实测曲线发现了设备存在的问题。研究结果为SP定宽机的设计与维护提供了重要依据。

| Abstract: | A finite element technique and testing means are applying on the impulsive load of slab sizing press mill of Shanghai Bao Steel Corp., 1580 Workshop. The change rule of impulsive load is offered, based on the analysis of stress and flowing regular of metal on the slab. The causes of the slab disfigurement are explained. By the dynamic testing, the characteristic of acceleration and contact-impact force of hammerhead is validated, the testing results are consistent with calculation. Through the dynamic characteristic of hammerhead, the existent problems of the equipment are found, and these conclusions provide foundation for the design and maintenance of the SP. |
