| 为提高USB接口数据传输的稳定性和延长使用寿命，课题组对弹片结构进行了改进。基于弹片压力变形理论和库仑摩擦定律，同时考虑弹片接触大变形的关键因素，运用ANSYS Workbench软件建立了某型号USB数据接口球头弹片和接头接触的力学模型；运用有限元方法，对接头与数据接口球头弹片插合过程进行仿真分析，对比分析了插合过程中球头弹片的力学特性的理论计算和仿真分析结果。研究结果表明：球头弹片的3种结构参数对其力学特性存在影响，原始结构设计存在缺陷；依据仿真分析的结果对3种结构参数进行调整，获得了既能满足其材料屈服强度又具有良好力学性能的结构参数范围。研究结果为高性能USB数据接口的结构优化设计与可靠性设计提供了参考依据。 |

| In order to improve the stability of USB interface data transmission and prolong the service life, the structure of the spring piece was optimized. Based on the pressure deformation theory of spring piece and Coulomb law of friction, and considering the key factors of large deformation of spring piece contact,the mechanical model of the contact between a certain type of USB data interface spring piece with ball head and the plug was established by using ANSYS Workbench software.The simulation analysis of the plug and the data interface spring piece with ball head insertion process was carried out by using the finite element method, and the theoretical calculation and simulation analysis results of the mechanical characteristics of the spring piece with ball head in the insertion process were compared and analyzed. The results show the influence of three different structural parameters of the spring piece with ball head on its mechanical characteristics as well as the defects in the original structural design. According to the results of simulation analysis, the three structural parameters of the ball head spring piece is improved and the range of structural parameters which can meet the material yield strength and have good mechanical properties is obtained.The research results provide a reference for the structural optimization and reliability design of high performance USB data interface. |
