| Abstract: |
| To improve the precisions of pose error analysis for 6-dof parallel kinematic mechanism (PKM) during assembly quality control, a Sobol sequence based on Quasi Monte Carlo (QMC) method is introduced and implemented in pose accuracy analysis for the PKM in this paper. The Sobol sequence based on Quasi Monte Carlo with the regularity and uniformity of samples in high dimensions, can prevail traditional Monte Carlo method with up to 98.59％ and 98.25％ enhancement for computational precision of pose error statistics. Then a PKM tolerance design system integrating this method is developed and with it pose error distributions of the PKM within a prescribed workspace are finally obtained and analyzed. |
