Collision dummies, an important test device for automobile safety detection, are increasingly used in the field of automobile safety. Compared with a real person, the biological fitting performance, the accuracy and the repeatability of the working state of the collision dummy are important indexes for considering the performance of the collision dummy. The skin of the dummy, which is the first line of defense of the crash dummy, plays an important role in the crash test process. At present, the research on the preparation of the skin of the fake skin at home and abroad is not very important, the polyethylene or the polyvinyl chloride with single component is mostly adopted, and the processing method also lacks the standardized unified standard. The individual manufacturers abroad use the manual sewing method to coat the large skin outside the combined metal framework or sensor, and the academic papers in China use the methods of pouring and the like to make the skin be adhered outside the framework. However, both methods have a problem that the thickness and uniformity are difficult to ensure. At the same time, the difficulty of replacement is also a challenge.
At present, the skin of a collision dummy used by each large automobile manufacturer avoids the problem of frequent use, namely, after few collision times, the skin is damaged, the skin replacement step is complicated, the time is long, and great inconvenience is brought to production and testing.
