1005/2010 Development of Finite Element Method of Regulation and Verification by Tests

<div class="section abstract"><div class="htmlview paragraph">A verification study was carried out by performing virtual analysis studies of the 1005/2010 (Document 02019R2144-20220905/COMMISSION IMPLEMENTING REGULATION (EU) 2021/535) standard applied to M and N class vehicles as required by the regulation.</div><div class="htmlview paragraph">In this context, material tensile tests, three-point bending tests, and, finally, torso tests were performed. Material parameters were obtained with the data obtained from the physical material tensile tests. This material data was used as input for finite element analysis. With the three-point bending test, the deformation of the profiles against the force was measured and the weld areas were examined. The results obtained were compared with the three-point bending finite element analysis results. Since the outputs of the tests and finite element analysis were consistent, the torso test and finite element analysis were started.</div><div class="htmlview paragraph">In the physical torso test, the regulation states that each towing device installed on the vehicle must be able to withstand a static force in tension and compression equivalent to at least half of the maximum technically permissible loaded mass of the vehicle. Under these conditions, compression and tension loads were applied to the towing device in the vehicle axis. During the test, force–displacement data were recorded with a load cell on the piston applying the load. The exact loading conditions were applied in torso finite element analysis, and the analysis results were compared with the test results.</div><div class="htmlview paragraph">As a result of the comparison, it was seen that it remained within approximately 5% error rate and met the accreditation requirements. Since the accreditation certificate is obtained in future designs, physical tests are prevented, and type approval certificates can be obtained with finite element analysis. In this way, time and cost losses have been reduced.</div></div>
