Computational modelling of vehicle interior components for impact applications: Thickness analysis

This paper presents some modelling techniques useful for the optimisation of numerical models of vehicle interior parts in terms of improving the structural response in impact applications. A procedure regarding the random distribution of thickness of the elements for a selected area within a user-specified tolerance is presented. Procedures implemented in a custom-written code and the algorithms used for the random distribution are also presented. This was required because the parts presented some deviations from the nominal value (of thickness), probably due to the manufacturing process. With experiments performed with equipment constructed according to ECE R21 regulation, the results obtained using three numerical models are compared and solutions for numerical modelling are presented. Results (accelerations: maximum, average, at peaks; time: peak time, time interval between two peaks; coefficient of restitution) obtained using the numerical models were evaluated and compared with the experimental data.
