Abstract
In order to explore the impact of different structural design parameters
and environmental factors on the performance of the hydrostatic guide rail, the
flow field inside its oil chamber is simulated, which provides direction and guidance for the design and optimization of the guide rail system. Based on the theory of fluid lubrication and the Reynolds equation, numerical simulations are
performed through a mathematical model. The results suggest that the bearing
capacity of the oil film increases with the oil supply pressure. The film thickness
and the film stiffness share a positive correlation. Different oil film thickness and
different input pressure parameters can have a significant impact on bearing capacity and oil film stiffness. The correlations identified in the present analysis can be
used as a basis to optimize the guide rail design.
