摘要

以金属带式无级变速器圆弧段金属块接触特性为研究目标,建立了圆弧段金属块挤压力数学模型和有限元模型,并运用两种方法进行了金属块接触应力和变形量的数值计算,结果显示压应力和变形量的数值解与解析解在规律上基本一致,但由于金属块几何形状简化时接触面积减小导致解析解数值较高。随着金属块厚度的增加,z方向压应力随金属块厚度减小很快,其符合圣维南原理。本研究为金属块结构优化等内容的开展奠定了一定的理论基础。

Abstract

Taking the contact characteristic of the arc segment metal block with metal belt type continuously variable transmission as study object,the mathematical model and finite element model are established.The results show that the numerical solution of the stress and deformation is basically the same as that of the analytical solution,but the numerical value is higher,the reason is that the contact area of the metal block is reduced. With the increase of the thickness of the metal block,the compressive stress decreases gradually in the z direction,but the rate is very fast,it meets to Saint Venant principle. This study lays a theoretical foundation for the optimization of metal block structure and so on.
