Abstract: Computational fluid dynamics (CFD) was used to simulate the performance of a new kind of pneumatic levitation sucker (non-contact swirl sucker). Based on the existing structures, the improved program was proposed. The results of CFD simulation for improving structures show that in the case of little change in air consumption, suction has been significantly enhanced. That is much better than the performance of the original structure. Orthogonal test method was used to optimize the parameters of non-contact swirl sucker with the deflector body. The satisfied parameters are obtained.
