What are the car test?

Automotive test dummy is used for many evaluation indicators for automotive collision testing tests, including the acceleration impact values of each organ in the fake human body, the force and torque sizes of force and torque, and extruded deformation displacement, etc. Assessment body acceleration sensor signal, body deformation amount, after collision, door opening conditions, and fuel leaks. Among them, a large part (especially in dummy, sensor signal data) is a collection process that needs to pass the electric measurement data acquisition system, and finally feeds back the test results to the test personnel to calculate the fake human harmony value and other evaluation indicators.

General Motor, who has a long history in collision test dummy design, is leading the global automotive industry to study the potential of a new type of collision dummy. This study will help automotive manufacturers and security experts better understand the causes of injuries in rear-end accidents.

This experimental collision dummy is known as Biorid, designed by Charle Ms Technological University in Gothenburg, Sweden, specializing in the evaluation of car seat constraints. The experimental dummy has a significant feature that each fake person is equipped with a 24-day spine that simulates the spine. This simulation spine allows the experimental dummy to reflect the natural sitting position of the car member and make the same neck movement like a rear-end collision.

To obtain an industry, Biorid must be able to obtain test results that can be repeatedly verified, which is essential for vehicle safety design and assessment.

In some cases, the number of channels of electricity measurement is more than 150, which involves the type of acceleration, force and torque, displacement, current and switching amount. It can be seen that the data acquisition system is a car crash test. A very important measurement link.

The above is a simple solution for the test of the Qinsun for the combustion fake people you do, if you need to purchase products, please consult: info@qinsun-lab.com.
