摘要:

为提高超大型环件轧制几何形状测量精度,提出一种基于多源信息融合的分阶段测量方法。该方法利用三个激光位移传感器实时数据,结合轧制进给和整圆定径阶段特性,分阶段精确测量环件直径增长速度、环心偏移及圆度误差。建立了环件理论直径增长速度模型和外轮廓圆度误差模型,分析了环件直径增长速度和圆度误差的形成机制。通过在ABAQUS软件中构建ϕ10 m超大型环件轧制有限元仿真模型,将所提多源融合方法与工业相机拍摄、单点激光测量进行对比分析,验证了所提方法具有更高的准确性,并探究了芯辊进给速度对环件几何状态的影响。最终,通过缩比轧制实验验证了所提方法的有效性,轧制末期环件外轮廓拟合精度达91.7%。

Abstract:

To enhance the geometric shape measurement accuracy in super-large ring rolling processes, a staged measurement method was proposed based on multi-source information fusion. This method utilized real-time data from three laser displacement sensors, combining with the characteristics of the rolling feed and rounding-sizing stage, to accurately measure the ring's diameter growth velocity, center offset, and roundness error in distinct phases. Theoretical models for the ring's diameter growth velocity and outer contour roundness errors were established, the formation mechanism of the diameter growth velocity and roundness error of ring were analyzed. By constructing a finite element simulation model of ϕ10 m super large ring rolling in ABAQUS software, the proposed multi-source fusion method was comparatively analyzed against industrial camera imaging and single-point laser measurement, which verified superior accuracy of the proposed method and the influences of the mandrel feed speed on the ring's geometric state were explored. Finally, the effectiveness of the proposed method was confirmed by scaled-down rolling experiments, with the outer contour fitting accuracy reaching as 91.7% in the final rolling stages.

Key words: super large ring, radial-axial rolling, center offset, roundness error, error separation
