Kia new K5 safety performance analysis Multi-angle collision analysis

[Automobile world maintenance] Optima is a car that Kia is positioned in the mid-size car, and the domestic model in the domestic market is called "K5". It was learned from the American Highway Safety Insurance Association (IIHS) that Kia Optima conducted a crash test at the agency. The new car was rated as 25% positive, 40% positive, side impact, top impact and neck protection. Received the highest rating and received the IIHS “2016 highest level safety assessment +” (2016 TopSafetyPick+) title. Many people in the eyes of the “Japan and South Korea car” security aspects are not dominant, the results of this announcement, K5 in all aspects of security protection in place, played a very good protective role. Overall evaluation The model tested this time is the US version of Kia K5. The IIHS crash test project is divided into 55% frontal collision, 40% frontal collision, side collision, top collision and neck protection. The highest rating was obtained in all five tests. In the most severe frontal 25% small-area crash test, although the 2016 K5 overall evaluation got "G", in terms of structural evaluation and calf/foot, it was “A” and “sufficient”. In the assessment, I got “A” and “other”, and all other scores were “G” (good). Kia K5 front 25% collision test due to the impact of the front 25% small area collision concentrated in the range of about 25% of the left side of the front, avoiding the main front energy absorption area, which means the buffer absorption of the vehicle under test The energy zone is smaller; the longitudinal beam that absorbs the collapse of the front absorbs almost no collision energy. When the impact occurs, the wheel is more likely to invade the cockpit, and the steering column, steering wheel and instrument panel are more easily displaced. After the impact, the 2016 Kia K5-A column was more severely deformed. In addition, the left front wheel of the test vehicle is obviously displaced and deformed. After a strong impact, the body structure deformed to varying degrees. Among them, the 2016 Kia K5 pushed the steering wheel 9 cm in the direction of the driver after the impact, and the steering column’s invasion range was 4 cm, which was within the safe range. The cockpit is basically in good condition. During the impact process, the driver’s simulated dummy’s inertia motion in Kia K5 is controlled quite well, without excessive offset, and the front airbag promptly pops out to provide sufficient protection for the head; the dummy’s head touches Although there is a rebound after the airbag, the coverage of the air curtain on the head side is in place. The airbag and the air curtain cooperate to fix the dummy’s head in the safe space, so as to avoid injury caused by touching the structure inside the vehicle. After the collision, the K5 driver’s leg space was invaded by different degrees of body parts. Although the hinge part of the body part invaded 14 cm, according to the data reading, the simulated driver’s leg in the Kia K5 was within the safe range during the impact. .
