Option 2: Energy Absorption
When an automobile loses control at interstate speeds, a rapid change in energy occurs from kinetic energy into sound, heat, and other forms. When considering the forces involved in the crash between an automobile and a road barrier, increasing the time over which the force is applied, known as impulse, can significantly reduce the severity of injuries for the occupants of the vehicle.
The force, F, can be determined by measuring the acceleration, a, and mass, m, of the vehicle and the use of Equation 1, assuming the force between the vehicle and barrier is the only force acting on the vehicle at the time of the accident. The acceleration is a useful measurement to not only predict the forces on the occupant of the vehicle, but also can be used to create an estimated velocity through integration (opposite mathematical operation of differentiation).
The task for this project option is to create a safer barrier system for interstate highway speeds to maximize the time over which the crash occurs. Other factors that should be considered in the design of the system would be the maximum safe speed of a vehicle that crashes into your barrier, as well as whether the vehicle “rebounds” off of the barrier or stays in contact with the barrier.
RULES OF THE PROJECT
TESTING AND REQUIRED CALCULATIONS
The following items will be used during the testing of each iteration of your safer barrier
