Description
Technical Field
[0001] The invention relates to a high-speed camera carrying device and belongs to the field of tire equipment. Background Art
[0002] As the connecting part between the car and the ground when driving, the performance of the tire directly affects the car's load-bearing capacity, braking, driving and handling stability. The tread block is the part of the tire that directly contacts the ground. The structural performance of the tread block directly determines the performance of the tire, especially the stiffness characteristics of the tread block, which plays an important role in the tire's force transmission, cornering, braking and lateral deviation. Therefore, the study of the stiffness characteristics of the tread block is the key to the development of high-performance tires. During the tread block rigidity research and testing process, it is necessary to observe the working conditions of the tread block with a high-speed camera, and during the observation process, it is necessary to adjust the position, camera angle, height, etc. of the high-speed camera to observe the tread block under test from multiple angles.

The degree of automation is low, and it is difficult to observe the tread blocks under test from multiple angles.
