| 摘要: |
| 针对薄壁角接触球轴承刚度分析中的多体接触协调变形的情况,以71718轴承为例进行了薄壁角接触球轴承的轴向刚度特性研究．根据单元大小对分析结果的影响确定合理的单元尺寸;利用所确定的单元尺寸建立71718轴承的三维有限元模型,并对其轴向刚度进行分析;搭建轴承轴向刚度测试平台,并利用该平台对71718的轴向刚度进行测试．实验结果与分析结果的对比可知,利用Hertz解析解计算时误差较大,利用有限元法得到的解与实际测试结果误差在10％以内． |

| Abstract: |
| For the problem of multi-body contact and co-deformation in the stiffness analysis of angular contact thin-section ball bearings, an angular contact ball bearing 71718 is taken to investigate the axial stiffness of the thin-section bearing. Firstly, the reasonable finite element dimension is acquired based on the influence of the element dimension on the finite element analysis (FEA) results. Secondly, the finite element model of bearing 71718 is established to analyze the axial stiffness characteristics. Finally, the bearing axial stiffness test table was set up to test the axial stiffness of bearing 71718. The comparisons between test results and analysis results show that the Hertz analytical solutions has large calculation errors, the finite element results are close to real results, and the error is less than ten percent. |
