Description

Technical Field

[0001] The present invention relates to the technical field related to vehicle puncture, and particularly to a vehicle debris puncture test device. Background Art

[0002] When a vehicle has a car accident, puncture phenomena will occur between the structures on the vehicle. Therefore, in order to test the real-time data when the vehicle structure or panel is punctured, it is necessary to conduct a puncture test on the structure of the vehicle in the laboratory to collect relevant puncture data. In the puncture experiment detection, the vehicle debris puncture test is an important step, which is a special detection device for evaluating the debris generated when vehicle parts or materials are punctured by sharp objects. Its core goal is to ensure vehicle safety and material reliability.

When puncturing the vehicle part materials from different angles, the generated debris is significantly different, and thus the relevant data of the generated debris is different.
