Testing

Drop Test

Turning Radius Test

Most of the testing was simple.  The chassis parts were put on a scale to evaluate the weight and the suspension was measured with a measuring tape to ensure one and a half inches of free movement.  To perform the drop test, a speed test was to be performed first to check the performance of the car.  The gearbox of the car was not working when the second drop test was run, so the performance test portion was dropped.  Then the car was dropped on its wheels from a height of two feet and a visual inspection was performed to make sure nothing had moved.  After the visual inspection, another performance test was done to make sure nothing internal was damaged as long as the drivetrain was working before the test.  The frontal impact test was performed with a speed test before and visual inspection and speed test as well.  Originally, the car was going to be driven at top speed into a wall to test the front bumper, but due to issues with the drivetrain the car could barely attain 5 mph.  To simulate a frontal impact at the 30 mph that the bumper was designed for, the car was wrapped in bubble wrap and dropped from a height of 30 feet onto the bumper to simulate a 30 mph impact.  The fourth requirement was tested by fully assembling the car then measuring the distance between a flat surface the car was sitting on and the bottom of the chassis plate at each wheel and in the center of the chassis plate to ensure there was no bending.   The final requirement was that the car be able to make turns with less than a three foot radius.  This test was performed by using painter’s tape to mark a three foot circle on the floor of the Fluke lab.  The car was then driven into the circle and turned around without touching the tape.
