中厚板轧机轧辊轴承座有限元分析与设计应用

FINITE ELEMENT ANALYSIS AND DESIGN APPLICATION OF ROLL BEARING CHOCK IN MEDIUM PLATE MILL

中厚板轧机轧辊轴承座承受较大的弯辊力和轴向力.为改善轧辊轴承润滑条件,对轴承座的承载区结构进行了优化设计.为确保其强度,需要模拟现场工况,从理论上分析计算了受力情况,并用有限元分析软件ANSYS仿真计算了承载时新轴承座的Von Mises应力分布,并采用两种不同的加载方式对比分析了仿真结果,计算出了轴承座的使用安全系数达到7.7.据此确定了轴承座的改进型新结构,在轧机上成功应用.

Roll bearing chocks of the medium plate mill bear greater bending force and axial force. In order to improve the lubrication condition of roll bearings, the bearing zone structure of the bearing chocks is optimized. In order to ensure its strength, it is necessary to simulate the field working condition. This paper analyzes and calculates the stress of bearing chocks in theory, and uses the finite element analysis software ANSYS to simulate the load-carrying capacity and Von Mises stress distribution of new designed chocks, and compares the simulation results by using two different loading methods, and calculates the application safety coefficient of bearing chock to reach 7.7. Based on this, new improved structure of bearing chocks is confirmed and applied successfully in rolling mill.
