Abstract：By using modal analysis function of ANSYS software , a constraint finite element modal analysis for a shield machine reducer box is carried out , and get the first 8 natural frequencies and corresponding vibration shapes.By comparing with the reducer box working frequencies , its design rationality is verified.Afterwards, the box structure is optimized and volume (quality) is cut down.Then analyzed a feedback mode of the opti-mized box, get the first 8 natural frequencies and corresponding vibration shapes again , these results are illus-trated with effect of changing the box structure on its natural frequency and the resonance possibility .Finally these problems which should be paid attention to in optimizing the box structural are pointed .
