Modelling of Two-Seat Connection to the Frame of Rail Wagon in Terms of Resistance at Impact Test

Open access

Abstract

This contribution explores how design changes can affect resistance of rail wagon seat-to-frame connections at impact test and proposes alternative way to construct such connections. Results were due to a nature of presented problem obtained by computer modelling using MSC Nastran with explicit finite element method solution invoked. Physical tests were also conducted and comparison with numerical results is presented.
