摘　　要：为提升纺织钢领类金刚石涂层(DLC)的抗冲击性能,延长纺织钢领的服役寿命,课题组通过ABAQUS建立了一种针对环锭细纱机纺织钢领系统简化冲击模型。该模型通过设置微小间隔模拟实况冲击距离,使冲击体速度贴近实际工况;并赋予钢领基体和涂层不同的材料属性以更加贴合实况。在此基础上,进行有限元数值模拟计算,将其结果与实际实验结果进行对照。结果表明:在多个不同初始冲击能条件下,仿真模拟结果与实际冲击实验结果非常接近且趋势一致,偏差在5%以内,由此验证了此冲击模型的正确性和仿真结果的有效性。采用控制变量法分析了不同冲击载荷下类金刚石涂层钢领基体和纯钢领基体的残余应力分布、冲击坑变形与载荷力大小以及系统的能量转换,考察了可能由冲击导致的冲击动力响应和涂层破坏形态,并对DLC涂层材料的选用提出建议。In order to improve the impact resistance of the diamond-like carbon(DLC) coating of the textile ring and prolong the service life of the textile ring, a simplified impact model for the textile ring system of the ring spinning frame was established through ABAQUS. The actual impact distance was simulated in the model by setting small intervals, so that the speed of the impact body was close to the actual working conditions. In addition, different material properties were given to the ring matrix and coating to better fit the real situation. On this basis, the finite element numerical simulation calculation was carried out, and the results were compared with the actual experimental results. The results show that the simulation results are very close to the actual impact experimental results under several different initial impact energy conditions, and the trend is consistent, with the deviation within 5%, which verifies the correctness of the impact model and the validity of the simulation results. The controlled variable method was used to analyze the residual stress distribution, impact crater deformation and load force, and the energy conversion of the system under different impact loads of diamond-like carbon coated ring substrate and pure ring substrate, the impact dynamic response and coating failure morphology possibly caused by impact were investigated, and the suggestions on the selection of DLC coating materials were put forward.
