摘要 对金属橡胶减振器按照刚度参数进行选配或在最终的装配过程中,经常会发生静态或动态性能的差异。如果能以不更换金属橡胶块为前提,通过改变金属橡胶块的压缩长度来改变金属橡胶减振器的使用刚度,将可降低产品的废品率。在进行相关理论分析后,通过10组压缩试验对分析结果予以验证。试验结果还表明在刚度变化相同的情况下,金属橡胶块压缩长度改变值在"软化"处理时比"硬化"处理时要大。此方法有效地提高金属橡胶减振器的成品率,节省生产成本并提高资源的利用。 Metal-rubber material is a typical kind of non-linear materials. In selection of stiffness parameters and final assemblage of metal-rubber absorbers, their dynamic performance can differ from the static performance very often. If the stiffness of the metal-rubber absorber can be changed by adjusting the compressive length of the metal-rubber component instead of replacing it, the rejection rate of vibration absorbers can be reduced. In this paper, this approach was theoretically analyzed and verified by 10 groups of compression test of the metal-rubber. The results show that for the same rigidity variation, the change of the metal-rubber compressive length in“softening”treatment is larger than that in“hardening”treatment. This method can effectively raise the product rate of metal-rubber dampers, save production costs and use resource reasonably.
