Design and Finite Element Analysis of Needle Beam Trolley for Tunnel Construction
As a special equipment of circular tunnel lining,the needle beam trolley plays an indispensable role in tunnel con-struction.In this paper,aiming at the problems existing in the tunnel corner of the needle beam trolley,structural improvement design is conducted that the length of the lining is longer,and the trolley does not need to be dismantled.The SolidWorks soft-ware is used for the needle beam trolley components modeling,and finite element analysis on the needle beam structure is con-ducted through SolidWorks Simulation platform.The results show that the strength can meet the requirements of use,which provides theoretical guidance for the subsequent characteristic research of the needle beam trolley.
