Dummies, also known as anthropomorphic test devices (ATDs), are essential tools for conducting crash test Finite Element simulations to evaluate the safety of vehicles and other transportation systems. These dummies are designed to simulate the human body's response to a crash and collect data on the forces, accelerations, and other variables experienced by the body during impact.
Crash test dummies are made up of different components, including a head, neck, chest, abdomen, pelvis, and limbs, which are connected by joints that mimic the human body's range of motion. They are typically made of various materials, such as plastic, steel, and rubber, that can deform and absorb energy during a crash.
Types of dummies used in crash test simulations:
-
▶ Hybrid III: This is the most commonly used dummy for evaluating the safety of passenger vehicles. It has sensors in the head, chest, pelvis, and other body parts that measure the forces and accelerations experienced during a crash.
-
▶ THOR: This is a newer generation of dummy that is designed to be more biofidelic or more representative of the human body's response to a crash. It has additional sensors and improved joint mechanisms that provide more accurate data.
-
▶ WorldSID: This dummy is designed to evaluate the safety of side impacts and is used to assess the effectiveness of side airbags and other safety features.
In addition to these dummies, there are also specialized dummies used for evaluating the safety of child passengers and pedestrians.
