Crash test simulations use dummies to replicate human bodies in a crash situation, providing valuable information for car, airplane, and boat safety. The first crash test dummy was developed in 1949, replacing the use of cadavers and live animals. Standardized tests using sophisticated technology provide valuable information for researchers to determine vehicle safety.
A simulated crash test is a full-scale replica of a human being that is designed to behave as much as possible like a human body in a crash situation. Although most people think of car safety when they hear the words “crash test simulation,” these valuable tools are also used in airplanes and other vehicles to determine how safe they are. Crash test dummies can experience broken limbs, broken necks, severed arteries, and a variety of other trauma that a real person might experience in a crash; the only thing fools can’t do is drive a car.
Almost as soon as the automobile was invented, it began maiming people. Car manufacturers quickly realized that they needed to implement safety features and that they needed to test their vehicles to figure out how to make them safer to drive. Manufacturers of other forms of motorized transportation, such as planes and boats, were also quick to realize the value of crash tests, but the researchers faced the problem of how to test the safety features. Obviously, throwing a car on the market and seeing what happens is not a good idea, so the researchers needed a reasonable approximation of a human body to see what actually happens when a car hits a wall at high speeds, or when someone jumps. of the. an aircraft.
The first investigative tools in impact research were actually cadavers, which make reasonable replacements for living people, except that the use of cadavers is fraught with ethical issues. In addition, the cadavers are not uniform, which means that the tests carried out on them are not scientific or repeatable. Some research facilities turned to live animals such as pigs, but faced similar issues of uniformity and ethical protests. As a result, the crash test dummy was created.
The first crash test dummy was Sierra Sam, which was developed in 1949 to test ejection seats on aircraft. Since then, numerous versions of the crash test dummy have been created, and the technology only gets more sophisticated. Crash test dummies now come in entire families, allowing safety researchers to conduct safety tests on facsimiles of men, women, children, and infants to consider the range of injuries that may be involved in a crash. A high-end crash test dummy is sophisticated machinery, and crash test dummies can fetch impressive prices.
A dummy test is standardized, so the tests in which it is used are repeatable. Additionally, crash test dummies can be used to gather valuable information about how quickly various parts of the body move upon impact. A large number of sensors are used in a crash test simulator to provide a complete picture of a crash, from the moment the vehicle being tested crashes into something until it comes to a stop. Using data about how long a real human can survive, researchers can determine how safe a vehicle is.
