The results show that the axial rigidity is much difference and the radialrigidity similar between the accurate calculation and the brief calculation.
计算数据表明，轴向刚度的精确计算与简化计算结果相差较大，而径向刚度的精确计算与简化计算值相差不大。

Second, the calculation formula of radialrigidity is deduced according to the deformation of rollers under the radial load with axial position preload.
其次，由轴向定位预紧轴承受径向载荷时各滚子的变形，推导出轴承的径向刚度计算公式；

We want to control the radialrigidity by adjusted the structural parameter, so that the mechanical capability of the new structure would be similar to cylindrical shell.
