same is true immediately after impact. During impact, the object must stop its downward course, and reverse its direction. This is where the high level acceleration occurs. Acceleration is, by definition, the rate of change of velocity. The faster the object changes from downward velocity to upward velocity, the greater the acceleration. (5)In IIHS's side impact crash test, two SID-IIs dummies representing small (5th percentile) women are . one different measures are recorded by each dummy in IIHS’s side impact crash test, including: • Head acceleration (three directions from the head’s center of gravity) • Axial force, anterior-posterior force, lateral-medial force .
Side impact dummies (SID) are specifically instrumented to help engineers design safety features that protect occupants in side impact crashes. These collisions differ from frontal impacts because there is less vehicle structure to protect occupants, with the most significant forces traveling through the pelvis, shoulder and head from one side .In IIHS's side impact crash test, two SID-IIs dummies representing small (5th percentile) women are . • Head acceleration (three directions from the head’s center of gravity) • Axial force, anterior-posterior force, lateral-medial force, anterior-posterior bending moment, lateral-Some of the vehicles evaluated in the side impact test program have been used in the IIHS bumper test program. Such vehicles have been subjected to an impact on the front and/or rear of the vehicle at either 5 km/h (3.1 mi/h) to the corner or 10 km/h (6.2 mi/h) across the full width European UN-R135, American FMVSS 214, E-NCAP and US-NCAP long time ago had side pole impact test items. China’s side pole impact regulations started relatively later: On March 25 of 2019 year, recommended national regulation “protection of the occupants in the event of a lateral pole collision” (GB/T37337-2019) was approved and issued by .
Each test vehicle and its occupants were instrumented with accelerometer arrays to measure and quantify the impact severity at various inter-vehicular angl . and 2.1 ± 0.9 g at the head. The average resultant acceleration for the right-front passenger occupants was 1.8 ± 0.7 g at the lumbar region, 2.0 ± 1.1 g at the cervicothoracic region .The vehicle crash acceleration curve is an important measured data which can represents a time history response of a vehicle during an impact test. To investigate the crash acceleration curve not only can realize the dynamic response and energy change of the impact process, but also able to assess the severity of occupant injury during a crash .Cars are made to collapse upon impact extending the time of the collision and lessening the impact force. That's why they can't be too durable. . What is dangerous for a human is the high acceleration or deceleration given at a specific amount of time.

These values also are the IARVs for out-of-position testing of side airbags with 5th percentile female dummies and represent about a 3 percent risk of serious neck injury (Mertz et . high forces in side impact . How Charpy impact tests are performed. Specimen Preparation: A small, standardized specimen, usually a rectangular bar with a V-shaped notch machined on one side.The notch creates a stress concentration that promotes fracture when impacted. The test setup includes a pendulum hammer, a notched specimen holder, and a digital or analog .
One fundamental issue is how to evaluate side impact air bags with a component test that realistically simulates the kinematics of a full scale side impact crash test. This paper presents a test methodology . Correlation of this type of testing is based upon both the vehicle response and the acceleration responses of a Side Impact Dummy .
The results of side impact barrier tests for the same lower mid-size car are shown in Figure 3. The higher velocity 55 kmIhr, 27° angle side impact test is a "deploy" event requiring restraint system response, while the lower velocity 15 kmIhr, 90° angle side impact is a "non-deploy" event that requires no restraint system response.LABORATORY TEST PROCEDURE FOR FMVSS No. 214, DYNAMIC SIDE IMPACT PROTECTION -Moving Deformable Barrier Test Requirements Using Advanced Test Dummies- ENFORCEMENT Office of Vehicle Safety Compliance . ½ is the resultant acceleration magnitude in g units at the dummy
