| 中文摘要: |
| 概述双涂型胶粘剂粘接原理和橡胶与金属粘接失效模式，针对某型一系橡胶弹簧（一系弹簧），采用Sigmasoft仿真软件对胶料充模和保压硫化过程进行分析与计算。研究表明：一系弹簧橡胶与金属粘接失效的根本原因为外套径向尺寸公差较大，径向封胶效果不佳，外套边缘硫化压力小；将一系弹簧外套径向封胶改为垂向封胶，并将原来的两瓣模结构改为整体模结构，一系弹簧外套边缘硫化压力增大，可以彻底解决橡胶与金属粘接失效问题。 |
| 英文摘要: |
| This paper summarized the bonding principle of double coated adhesive and the bonding
failure modes between rubber and metal. For a certain type of primary rubber spring（primary spring），the
mold filling process and pressure maintaining vulcanization process were analyzed and calculated by using
Sigmasoft simulation software. The study showed that the root causes of the bonding failure between rubber
and metal of the primary spring were that the radial dimension tolerance of the outer sleeve was large，
the effect of the radial sealing compound was poor，and the vulcanization pressure at the edge of the outer
sleeve was small. By changing the radial sealing of the outer sleeve of the primary spring to vertical sealing，
replacing the original two-lobe mold structure by integral mold structure，and increasing the vulcanization
pressure at the edge of the outer sleeve of the primary spring，the problem of bonding failure between rubber
and metal was completely solved. |
