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

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.
