Analyze the role of the car Crash Test Dummy to simulate the human body part

Automobile Crash Test Dummy is mainly used as an instrument for safe driving test experiments of automobile companies. It simulates various parts and structures of the human body. At the same time, it has a wide range of sensors that can detect the simulated human feelings in various situations during the automobile driving test in time. In order to evaluate the safety performance of the car, Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. is a manufacturer, and customers in need are welcome to inquire in time. In addition, the R&D technical engineer of Qinsun made some simple explanations on the role of the simulated parts, hoping to help customers.

The head of the Crash Test Dummy is an aluminum skeleton, covered by rubber as a "skin". Three acceleration sensors are installed inside to test the acceleration and impact force on the head during a collision.

The measuring device mainly measures the impact force on the neck during a collision, and the amplitude of the neck bending back and forth and moving left and right after the force is applied.

The arms of the simulator do not carry any sensors, so they will swing freely in a collision. Although this is unlikely to happen in reality, the protection of the arms is actually very important now, and it is also very important. Not easy to do. However, there is currently no good test index and measurement standard.

Ominous Ministry (frontal impact):
Crash Test Dummy has metal ribs of the same column size to test the ribs of front-row occupants when they receive a frontal impact. The impact force on the chest cavity has been deformed under the impact.
Crash Test Dummy
The violent part (side impact):
The EuroSIDII simulator is used for side impact, and three different sensors are mounted on the three ribs to test the extent and speed of the compression of the chest cavity during side impact.

The dummy’s abdomen is equipped with a sensor that can test the impact force to test how much impact force will cause abdominal injury.

A sensor is installed on the waist to record how much force in a collision will cause joint dislocation and pelvic fracture.

The test uses HybridIII to simulate a human, and the test area includes the pelvis, thighs, and knees. The sensor installed in the thigh is responsible for collecting data when receiving a frontal impact and recording the area and extent of the injury. In a more severe impact, the femur is torn and dislocated. A special sensor is responsible for measuring driving The impact force received by the player’s knee from the steering wheel.

The sensor in the calf is responsible for measuring how hard the simulated human calf will fracture, bend, and be squeezed after being hit. It also tests the probability of injury to the knee, calf bone, ankle bone, and the connection between the calf bone.

The probability of injury to the driver’s foot in a frontal impact is measured, and the probability of injury is determined by the amount of deformation near the pedal where the foot is placed and the distance compressed into the car.

The above is the detailed content of Crash Test Dummy that the Qinsun will answer for you in detail. I hope to help you. Of course, if you want to buy a product, you are welcome to come to consult.
