Design and Finite Element Calculation for Driving Shaft of Eccentric Multi-Axes Rectangular Shield Machine

Abstract:

This paper introduced the characteristics of eccentric multi-axes rectangular shield machine and made comparisons to traditional earth pressure balance shield machine. And introduced structure form of eccentric multi-axes, and carried out calculation of cutter head driving. The author completed the finite element calculation of eccentric axis with COSMOS Works, the results of calculation shows that maximum stress occurs at the place at gear keyway of eccentric shaft, but the eccentric shaft can satisfy the requirements in shield design according to big load in cutting soil. Finally, the eccentric shaft was applied in several engineering cases without any structural problems.
