Since the 1970s, crash test dummies – mechanical substitutes for the human body – have been used to determine the safety of cars. These tests determine the effectiveness of seat belts. and safety features of new vehicles.
So far, the most widely used mannequin has been based on the average build and weight of a male. However, women make up about half of all drivers and are more likely to be injured in such crashes.
The mannequin, sometimes used in place of the female one, is a smaller version of the male mannequin, about the size of a 12-year-old girl. With a height of 149 cm and a weight of 48 kg, she represents only 5% of women by today’s standards.
However, a group of Swedish engineers has finally developed the first mannequin, or, to use a more technical term, a seat assessment tool, built on the average woman’s body. His mannequin has a height of 162 cm and a weight of 62 kg, which is more typical for the female population.
How are accidents measured scientifically?
Several times a day, traffic accidents are simulated and their consequences are analyzed. The dummy’s sensors and transducers provide potentially life-saving data by accurately measuring the physical forces acting on each part of the body in a crash.
The team in charge records data such as impact speed, crush force, flex, body torsion and braking speed. Its purpose is to see what happens to the dummy’s biomechanics during low impact rear impacts.
According to the US government, when a woman has an accident from automobile have three times more likely to get whiplash in a rear-end strike than a human. Although whiplash is not usually fatal, it can lead to physical disability.
These statistics are what drives Astrid Linder, director of road safety at the Swedish National Institute for Road and Transport Research, who is leading the main investigation, the BBC told the BBC.
Dr. Linder believes her research could help determine how cars will be built in the future and highlight key differences between men and women (height and muscle mass). accidents traffic can be safe if we improve road safety.
