Oszacowanie wartości EES samochodu osobowego przy wykorzystaniu metody elementów skończonych
Estimation of the EES value of a passenger car using the finite element method

Summary/Abstract: In the article the results of calculations of the EES parameter (energy equivalent speed) of a passenger car damaged as a result of a collision with an atypical obstacle, such as the rear of the wheel loader are presented. The finite element method (FEM) available in the PC-Crash software was used in the calculations. It is shown that the finite element method can be successfully used in such cases. It was also noticed that the stiffness of the windshield of a passenger car structural model has an excessively strong effect on the deformation of the roof and the value of the EES parameter. A simplification of the model by removing the windshield is proposed.
