机械卡盘设计中的计算误差分析与应用

Analyses and Usages of Calculation Errors on Designing Mechanical Chuck

通过对普通机构二维力因素影响的分析,利用修正公式计算求值,以修正单因素影响最大值计算所产生的误差。利用这一计算方法,对CD-3型钻机卡盘进行了计算,得到了正确的设计结果,说明用修正公式对多因素影响采用单因素影响最大值计算进行修正是可行的。

After analyzed the effect factors of the two dimension forces applied on convenient mechanism, the modified equations are used to calculate the values. So that the errors of maximum calculated value resulting from individual effect factor can be corrected. The chuck of CD-3 drilling rig was calculated by this method and right results were got out. That shown it is feasible to correct the maximum calculated value by individual factor effects instead of by multifactor effects.
