摘要
本文基于圆形汽车高压连接器的结构特点,以悬臂梁和简支梁两种常见弹性梁数学模型为理论基础,系统对比分析两种模型的优缺点。结合接触件正向力、接触点数量及插拔力等关键性能指标,设计多种圆形接触簧结构并通过仿真优化筛选,确定最优结构方案。通过建立接触簧结构插拔力与永久变形量的有限元法仿真模型,明确了接触簧的最佳内圆半径R,并深入分析了内圆半径R对插拔力的影响规律。
Based on the structure of a circular automobile high-voltage connector and the mathematical models of two common elastic beams,the article compares their advantages and disadvantages,and designs a variety of circular contact spring structures,combining factors such as the positive force of the contact part,the number of contact points and the insertion and pulling force,and determines a contact spring structure.Finite element simulation of the plugging and pulling force and permanent deformation amount of contact spring structure was established to determine the optimal inner circle radius R of the contact spring,and the influence of the inner circle radius R on the plugging and pulling force was analyzed.
