动态试验数据集

动态试验数据集主要面向高加速轮胎动态加载试验研究、基于轮胎qf等需求建设。高加速加载轮胎在使用中，由于工作强度大、环境恶劣，会造成花纹严重磨损、内部裂纹扩展以及气泡增多甚至爆胎等现象。而当前对使用中的轮胎的检测主要依靠人工检测等，没有成体系的检测设备和理论依据支撑。往往是根据人眼观测胎体下沉量、胎面裂纹等表观现象判断胎压、表面磨损等情况，结合检测人员的经验来推测轮胎的服役情况及剩余使用次数。虽然高加速加载轮胎的外部损伤容易检测，能够被及时发现止损，而其内部结构的断裂则难以发现，导致了高加速加载轮胎的损伤检测时的可靠性降低。在等效试验台进行相应试验，并结合三维数字图像相关技术对轮胎表面的离面位移、主应变等力学参量进行记录，数据量10Mb。

This dynamic test dataset is primarily developed for high-acceleration tire dynamic loading test research and demands such as tire qf. During operation, high-acceleration loaded tires suffer from severe tread wear, internal crack propagation, increased air bubbles and even tire blowout due to high operating intensity and harsh environments. Currently, the inspection of in-service tires mainly relies on manual inspection and similar methods, without systematic testing equipment and theoretical support. Inspectors usually judge tire pressure, surface wear and other conditions based on naked-eye observed apparent phenomena such as carcass sinking amount and tread cracks, and estimate the service status and remaining service cycles of tires combined with their professional experience. Although external damage of high-acceleration loaded tires is easy to detect and can be found timely to avoid losses, internal structural fractures are difficult to detect, which reduces the reliability of damage detection for such tires. Corresponding tests are conducted on an equivalent test bench, and mechanical parameters including out-of-plane displacement and principal strain on the tire surface are recorded via 3D digital image correlation technology, with a total data volume of 10 Mb.
