FE Analysis of ECER 29 Load Cases and its Correlation with Test Results

摘要

The application of virtual simulations of crash has become an integral part of the vehicle development process. Virtual simulation offers opportunities to reduce development time and the number of physical prototypes consumed for design verification and validation. With the continuously increase of new accident and regulatory scenarios the dependency to virtual simulation and validation is becoming an inseparable factor in product development. This paper presents simulations that are performed to verify various safety aspects to ensure crashworthiness of the truck cabin. The cabin structure was evaluated for various load cases as per ECER 29 rev 2.0 safety regulation. The FE model and simulation methodology was validated through physical testing and correlated for frontal impact test and roof strength test as per AIS 029/ECE-R 29 rev 2.0. Paper also discuss on the issue faced in correlation of test vs. Virtual validation using explicit solver.
