Summary
This study presents data from pedestrian impact tests using Post Mortem Human Surrogates (PMHS) to validate vehicle impact dummies. Findings offer crucial insights for improving pedestrian safety dummy biofidelity.
Area of Science:
- Biomechanics
- Injury Biomechanics
- Automotive Safety
Background:
- Biofidelity of pedestrian impact dummies requires validation against full-scale test data.
- A simplified generic vehicle-buck was developed for representative pedestrian impact simulations.
- Previous work established trajectory corridors from these tests.
Purpose of the Study:
- To provide a companion dataset detailing kinematic and kinetic data from pedestrian impact tests.
- To describe head velocities, body accelerations, angular velocities, and forces.
- To document observed injuries in Post Mortem Human Surrogates (PMHS).
Main Methods:
- Conducted three 40 km/h lateral impact tests using PMHS and a generic vehicle-buck.
- Collected data on head/body kinematics, impact forces, and injury outcomes.
- Developed velocity corridors incorporating test data and rigid neck predictions.
Main Results:
- Head accelerations exceeded 80 g before windshield contact in two tests.
- Head angular velocity surpassed 40 rad/s before windshield contact in all tests.
- Peak head velocity relative to the vehicle exceeded the initial impact speed in all tests.
Conclusions:
- The presented kinematic and kinetic data serve as a valuable resource for pedestrian dummy development.
- Results aid in the evaluation and refinement of biofidelity for injury assessment tools.
- This dataset supports advancements in pedestrian safety technology.

According to Newton’s second law of motion, the rate of change of the momentum of an object is the net external force acting on it. The total change in momentum between two timepoints thus depends on both the external force acting on it and the time over which it acts. Describing this mathematically, the total change of an object’s motion is proportional to the force vector and the time over which it is applied. This product is called impulse.

01:15Elastic Collisions: Case Study
21.0K
Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.

When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².
