摘要
恒流闭式静压导轨修正计算法是采用力学计算和有限元分析相结合的方式,得到静压导轨油腔处的变形,在修正系统平衡方程的基础上,修改工艺参数,减小导轨基础件在负载条件下的刚性变形对静压导轨参数的影响。实践证明,修正计算法能提高设计的精度。
Mechanical calculation combined with finite element analysis is used in amended calculation for the constant current closed hydrostatic guideway. Through this calculation, the deformation in the oil reservoir of hydrostatic guideway was gotten. Based on the equilibrium equation of correction system, technics parameters were modified so as to minimize the impact of rigid deformation that caused by the guideway＇s basic element in reduced load condition on the hydrostatic parameters. Practice proves that the accuracy of design can be improved by amended calculation.
