Crash-Testing Car Bumpers: How Manufacturers Ensure Your Safety
Car bumpers are designed to protect both the occupants of the vehicle and pedestrians in the event of a collision. But how do manufacturers ensure that their bumpers provide reliable protection? The answer lies in crash-testing.
Crash-testing is a method used by automotive manufacturers to evaluate the performance of vehicles and their components during crashes. In particular, they use this method to evaluate the crashworthiness of the car’s bumper.
The process begins with a computer-generated model of the bumper design, followed by analyzing its strength and stiffness. After the initial design, physical prototypes of the bumper are created, and these prototypes undergo various collision tests to assess their performance.
One of the most common tests that bumpers undergo is the low-speed crash test. This test involves crashing the vehicle into a stationary barrier at a speed of approximately 5mph. The test examines the bumper’s ability to absorb the impact of the crash and minimize damage to the car’s body.
The crash-testing procedure also evaluates the bumper’s ability to protect pedestrians during collisions. The test involves using a crash test dummy to simulate a pedestrian being hit by the front of the vehicle. The bumper must be designed to absorb energy from the impact and minimize injuries to the pedestrian.
In addition to these tests, manufacturers may also conduct high-speed crash tests to evaluate the bumper’s performance in more severe collisions. In these tests, vehicles are collided head-on or at an angle with a barrier at speeds of up to 35mph.
To ensure their safety, vehicles are required by law to meet specific safety standards. In the United States, for example, the National Highway Traffic Safety Administration (NHTSA) establishes safety standards for motor vehicles.
In addition, many manufacturers conduct their own internal safety tests to ensure that their vehicles exceed government safety regulations. This testing is necessary to maintain their customer’s trust and safety.
In conclusion, automotive manufacturers go to great lengths to ensure that vehicles are designed with safety in mind. By crash-testing car bumpers and other vehicle components, they can provide a high level of safety to their customers during accidents. These tests significantly contribute to the safety of drivers, passengers, and pedestrians, and it is essential that manufacturers continue to invest in them.
