Abstract

A method for predicting the comfort level of passengers in an electric train car is proposed, taking into account the design features of the car and the position of passengers in the cabin. The methodology is based on mathematical modeling of the movement of a railway train along real track irregularities. The elastic properties of the supporting structure of the body are taken into account on the basis of the inclusion of a detailed finite element model of the car interior in a solid model of a railway train. In order to clarify the picture of dynamic effects on the passenger, the finite element model of the car is supplemented with finite elements describing the resilient properties of the passenger compartment floor. When assessing the comfort level, an analysis of accelerations obtained on computer models of anthropometric dummies integrated into a finite element calculation model of the body was performed. The mannequins were located in 26 positions in the passenger compartment. Two variants of car models are considered in the work: without taking into account the elasticity of the elements of the passenger compartment and mannequins and with their presence. The level of passenger comfort was assessed according to the criteria of the percentage of passengers experiencing discomfort when driving in a curve and a net dose of motion sickness when modeling the movement of the train along real track irregularities in the range from 20 km/h to the design speed. Comparison of the results obtained by the traditional method and the proposed in the work showed the possibility of data refinement up to 10%.
