摘要
为了准确分析空气弹簧接口改进为锥形接口后密封圈的应力,采用ANSYS软件建立了密封槽斜置和平置两种结构及密封圈的二维模型,对比分析密封圈的应力以及角度、环境温度变化对应力的影响。结果表明:锥形接口的锥角α约70°时密封圈的接触应力最大;密封槽平置结构中密封圈的接触应力比斜置结构中的大;密封圈截面直径为3.55 mm,压缩率为15%,密封槽平置且锥角α约70°是空气弹簧接口的一种优化的结构。
The two dimensional model of sealing groove and sealing ring is built by builtby ANSYS software, in order to accurately analyze the stress of the conical interface sealing ring, which is used to the air spring joint. The stress of sealing ring is compared and analyzed, and then the effect of angle and temperature on stress is analyzed. The results show that： the contact stress of the sealing ring is the biggest when the cone angle is 70 degrees;the contact stress of the sealing ring is larger, when the sealing groove is placed horizontally; the optimized structure of the conical interface is with the cone angle at 70 degrees, the sealing groove placed horizontally, the sealing ring cross section diameter 3.55 mm and the compression rate 15%.
