Design of Open-hydrostatic Slideway Driven by Linear Motor

The advantages and disadvantages of the open-hydrostatic slideway were introduced.The causes of drift motion were analyzed.Through introducing linear motor,the oil film thickness was regulated,improving the stiffness of the oil film and avoiding capsizing.And at the same time through analytical calculation and finite element analysis,force states of the slider were calculated,so as to improve the feasibility of the design.
