关键词： Tensile testing  

摘要： For the problem of tire force estimation deviation caused by the change of mechanical properties due to temperature rise during the rolling process，the vertical force estimation correction algorithm of heavy-duty tires based on thermal-mechanical coupling is studied in this paper. A variable temperature mechanical tensile test is carried out to obtain the mechanical parameters of the tire shoulder rubber with temperature change，and a heavy-duty tire thermal-mechanical coupling model is established. The ground loading test and modal test are carried out to verify the accuracy of the model. The grounding characteristics and mechanical characteristics of heavy-duty tires under the action of variable temperature vertical force are discussed，and the sensitive characteristics of the grounding parameters of the vertical force are analyzed，with the sensitive signal offset caused by the temperature rise during rolling corrected. A heavy-duty tire vertical force estimation model based on the Gaussian regression process is established and the vertical force estimation accuracy before and after temperature correction is compared. The results show that when the sensitive characteristic value after temperature correction is used as input，the maximum error of the model under vertical force loading of 10~80 kN is 3.45%，with good vertical force estimation effect ，and an improvement of the estimation accuracy by 9.17% compared with that before temperature correction. © 2025 SAE-China.

摘要： 当前面向跟踪器的对抗样本生成研究主要集中于可见光谱段，无法在多谱段条件下实现对跟踪器的有效攻击。为了填补这一空缺，该文提出一种基于多谱段的目标跟踪补丁式对抗样本生成网络，有效提升了对抗样本在多谱段条件下的攻击有效性。具体来说，该网络包含对抗纹理生成模块与对抗形状优化策略，对可见光谱段下跟踪器对目标纹理的理解进行语义干扰，并显著破坏对热显著目标相关特征的提取。此外，根据不同跟踪器的特点设计误回归损失和掩膜干扰损失对多谱段跟踪模型补丁式对抗样本生成提供指引，实现跟踪预测框扩大或者脱离目标的效果，引入最大特征差异损失削弱特征空间中模版帧和搜索帧间的相关性，进而实现对跟踪器的有效攻击。定性和定量实验证明该文对抗样本可以有效提升多谱段环境下对跟踪器的攻击成功率。
