摘要
在高强度数控车床主轴低载强化试验结果的基础上,通过数值插值方法,补充了试验数据,得到强化载荷与强化后疲劳寿命之间、强化次数与强化后的疲劳寿命之间的数学关系,然后根据这两个二维关系式,通过数学插值,得到低载强化空间曲面的离散点三维坐标,再根据这些数据点,用Tablecurve3d软件拟合得到低幅交变载荷作用下的三维强化曲面方程。
In high intensity low loading strengthening CNC lathe spindle based on the results of tests, the numerical interpolation method, added the test data, the strengthened load and enhanced fatigue life, between times of strengthening and strengthen the fatigue life afer the mathematical relationship between the two, then according to the mathematical interpolation formula, through two dimensional low loading strengthening, get the curved surface of discrete points 3D coordinate, again according to these data point, use Tablecurve3D software fitting alternating load get low-rising 3D strengthening curved face eouation.
