Background: Small Overlap (SOL) in IIHS is aggressive for most vehicles.Most of OEMs struggled to improve the performance for SOL.The Rating of most vehicles in SOL is not reasonable, although which can rate 5 star for US-NCAP.Objective: Find feasible solutions adapted to current designed SUV to have a good rating of structure assessment.Method and Material: Via Review the results of Small Overlap Oblique released by IIHS, feasible engineering solutions are concluded to have good rating of structure assessment for SOL.Then it is adapted to the designed SUV.A full vehicle LS-DYNA model is generated to verify the countermeasures.Results: For most of the vehicle have good rating, the following characters could be summarized: a.the vehicle pass by the rigid barrier, b.the tire will drop off the vehicle or the tire rim breaks, c.large enough curtain airbag to protect the head of occupant from impacting on hard components.the vehicle compartment deformed merely.Above key phenomena is reproduced well by the designed vehicle via employing the failure of the connections to wheel anchor and the tire rims.Conclusions: The tire dropping off or rim breaking reduce the load transferred to rocker, increase the deformable space and the deformation of vehicle body become smaller, which not only lead to good rating of structure assessment, but also create the pre-condition for good rating of occupant protection due to more friendly impacting pulse.
