DESIGN OF A METRO DOOR SYSTEM AND DETERMINATION OF MAIN LOADS

Abstract

This article discussed the determination of a metro vehicle’s door forces acting on its coarse structure. With previous articles addressing this issue, a definition of a specific reference vehicle was provided together with the collection of the normative requirements for metro vehicles. These form a basis for addressing the issue. The main objective hereof was to design a technical solution of a door system for the reference vehicle and create a parametric model of the door's forces acting on the vehicle’s rough structure. This model would serve to approximate and operatively quantify these force effects of the door to the vehicle’s structure by modifying the various input parameters. Therefore, it was necessary to create a mathematical model of the equilibrium conditions of the proposed door system and to quantify them using a developed software. Subsequently, these results served as inputs for the FEM analysis of the load-bearing components between the door and the vehicle’s structure.
