Abstract

Abstract:

It is very important to reduce the cost of tunnel lining trolley and steel consumption and indirect pollution emissions and control fog and haze. The two material combination modes for door frame structure of lining trolley used in Jiayuan Passengerdedicated Railway Tunnel on YinchuanXi′an Railway are analyzed by finite element method ANSYS. The column, beam and column bracing are fit to Beam4 and the other components are fit to Link8. Same boundary conditions are laid for simulation working conditions of the door frame; and then checking calculation and comparative analysis are carried out. The results show that the more than 2 t of material has been reduced for a single door frame after optimization; and good application effect has been achieved.

Key words: passengerdedicated railway tunnel, lining trolley, door frame structure, optimization
