Comparison With Experimental Data

Tramcar vehicles significantly differ from traditional railway vehicles both for the adopted structural configuration and design solutions and for the operating conditions. For this reason, a new numerical model specific for the analysis of tramcar dynamics has been developed by Politecnico di Milano. Before the numerical model can be adopted as a useful mean to analyse tramcar operational problems, the capability of the model to reproduce the actual tramcar dynamic behaviour has to be verified. The paper deals with the validation of the developed numerical model by means of comparison with experimental data.

Tramcar vehicles significantly differ from traditional railway vehicles for both the adopted structural configuration and design solutions and the operating conditions. For this reason, a new numerical model specific for the analysis of tramcar dynamics has been developed at Politecnico di Milano. Before the numerical model can be adopted as a means to analyze tramcar dynamics in typical operating conditions, the capability of the model to reproduce the actual tramcar behavior has to be verified. This paper deals with the validation of the proposed numerical model by means of a comparison with experimental data.

Simulation Results

A finite element model is proposed to investigate the effect of thickness differential on Limiting Dome Height (LDH) testing of aluminum tailor-welded blanks. The numerical model is validated via comparison of the equivalent plastic strain and displacement distribution between the simulation results and the experimental data. The normalized equivalent plastic strain and normalized LDH values are proposed as a means of quantifying the influence of thickness differential for a variety of different ratios. Increasing thickness differential was found to decrease the normalized equivalent plastic strain and normalized LDH values, this providing an evaluation of blank formability.
