Abstract:
      Objective To investigate the influence of structure error to the rotary precision of precision centrifuge. Methods Based on the software of LMS Virtual.Lab Motion, the influence of correlative structure error on the rotary precision (i.e., radius error of main shaft, dip error) of precision centrifuge was researched for the representative aerostatic bearing main shaft rotary system. The influence of the plate eccentricity error relative to aerostatic bearing axes and the plumb assembly error of aerostatic bearing axes as well as the plate perpendicularity error relative to aerostatic bearing axes to the rotary error of main shaft was obtained, and the rotary precision of main shaft rotary system was gained. Results The influence pattern of structure error on the rotary precision of precision centrifuge was obtained. Conclusion Along with the increase of the plate eccentricity error relative to aerostatic bearing axes and the plumb assembly error of aerostatic bearing axes as well as the plate perpendicularity error relative to aerostatic bearing axes, the rotary error of main shaft was linearly increased.
