| 摘要： | This report summarizes the work activity related to compatibility analysis in frontal collisions between passenger car and option 2 LTVs. This work involved both an overview analysis of structural interaction in frontal collisions between passenger cars and option 2 LTVs and the design of an over ride barrier for evaluating the secondary energy absorbing structure (SEAS) of the option 2 LTVs. Vehicle-to-vehicle frontal finite element simulations were conducted between compact passenger car (Neon) and option LTVfs (Ford F250 and Chevy Silverado). The Ford F250 has a cross-member type SEAS and the Chevy Silverado has a non cross-member type SEAS. The simulations were conducted with and without the SEAS. The effect of the SEAS on structural interaction between the two vehicles is evaluated based on the energy absorption and intrusions in the vulnerable vehicle. A parametric study was conducted with the option 2 LTV FE models to identify impact velocity, width and height of the ORB and the relevant assessment metrics to evaluate the strength of SEAS. Based on this study, an impact velocity of 25 mph was identified as an appropriate speed for the ORB test. A 1250 mm wide barrier with a top height aligned with the top of the Part 581 zone (508 mm) was identified as an appropriate barrier. Potentially, Kw400 could be used as an assessment metric for determining the strength of the SEAS structure. |
