The New ECE Regulation Brings Challenge on Commercial Vehicle

Abstract

Research and/or Engineering Questions/Objective 03 series of regulation No 29 of the Economic Commission for Europe of the United Nations (UN/ECE) entry into force on January, 2011. In this new regulation, most important is that it adds a new A-Pillars impact test and a modified roof strength test to evaluate the resistance of cab in rollover accident. Methodology Firstly, mechanism of commercial vehicle rollover accidents are analyzed in this paper and results show that A-Pillars, side sill, side and front door provide significant enhancements on impact. Then, working procedure verifies the contribution of structure modifications based on relative comparisons. Moreover, AHSS (Advanced High Strength Steel) is also discussed to increase the strength of the great weakness on current cab. Results All of the proposed methods are examined in FEM models and simulation results are confirmed to be satisfactory for giving enough survival space for occupant in frontal and roof impact tests. Limitations of this study Experimental validations will be included in scope of the next work. What does the paper offer that is new in the field in comparison to other works of the author: This study has almost carried simultaneously with the discussion of new version R29 from 2010 to now. The achievement involves relevant approaches acting at crumple zones and the determination of transfer paths between point of concern for deformation and place of impacting. Conclusion The aim is to develop a new or refined quantification methodology for improving commercial vehicle safety, based on computational, experimental and hybrid analyses.
