Detailed function of car test dummyRelease time: 2015-03-18 09:30
The car test dummy is mainly used as an instrument for safe driving test experiments in enterprises. The car test dummy simulates various parts and structures of the human body. At the same time, a wide range of sensors are distributed, which can timely detect the car test dummy during the car driving test. Simulate human experience in various extreme situations to evaluate the safety performance of the company; Here, Standard Group (Hong Kong) Co., Ltd. will introduce you in detail the structure and function of each part of the car test dummy.
Simulate the role of each part:
The head of the simulator is an aluminum skeleton, which is covered by rubber as "skin". Three acceleration sensors are installed in it to test the acceleration and impact force on the head during a collision.
The measuring device mainly measures the magnitude of the neck's impact force during a collision, and the neck's back-and-forth bending and left-to-right movement amplitude after the force.
The arms of the simulated person do not carry any sensors, so they will oscillate freely during a collision. Although this is unlikely to happen in reality, in fact, the protection of the arms is also very important at the same time. Not easy to do. However, there is currently no good test index and measurement standard.
Chest (frontal impact):
The dummy's metal ribs of the same size are used to test the ribs of the front occupants when they are subjected to a frontal impact.
Chest (side impact):
The side impact was simulated using EuroSID II. Three different sensors were mounted on the three ribs to test the amplitude and speed of the chest compression during a 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 was installed at the waist to record how much force during the collision could cause joint dislocation and pelvic fracture.
The test uses Hybrid III to simulate humans. The test area includes the pelvis, thighs, and knees. The sensor installed in the thigh is responsible for collecting the data of the frontal impact and recording the area and extent of the injury, and the femur is torn and dislocated under a more severe impact, while a special sensor is specifically responsible for measuring driving The impact of the steering wheel on the player ’s knee.
The sensor in the calf is responsible for measuring the simulated human calf's fracture, bending, and squeezing after being struck by multiple forces. It also tests the probability of injury to the knee and calf bone, ankle bone, and the connection between the calf bone.
Measure the chance of the driver's foot being injured in a frontal impact. The chance of injury is determined by the amount of deformation near the pedal and the distance compressed into the car.
