Mechanical Structure Design of Underground Logistics System Based on Passenger and Freight Transportation

摘要

Urban underground rail transit in China serves people,but at the same time,there is a problem of insufficient utilization of resources.To make more effective use of subway resources and alleviate traffic pressure,aiming at the problem of insufficient use of time and space resources in the process of Metro operation,this paper proposes a logistics system of underground railway based on the underground logistics system of passenger and freight co-transported.On this basis,the mechanical structure design of the system is carried out in the aspects of metro transportation and transformation of the Metro station.Firstly,the paper analyses the shortcomings in the current situation of Metro operation,discusses the underground logistics system of passenger and freight co-transportation,then focuses on the mechanical structure design of the system,and uses SolidWorks to simulate and analyze the mechanical structure to ensure the feasibility of the system and improve the utilization rate of Metro resources.
