编织-嵌槽型金属橡胶制备工艺及试验研究

Study on Preparation Technology and Tests of Knitted-dapped Metal Rubber

介绍了编织-嵌槽型金属橡胶的工艺方法。通过压缩试验,对比了编织-嵌槽型金属橡胶与普通金属橡胶的静态特性,研究了密度和厚度对编织-嵌槽型金属橡胶压缩性能的影响。结果表明:工艺参数相同时,编织-嵌槽型金属橡胶在承载能力、隔振频带以及性能的一致性等方面均优于普通金属橡胶;增大密度会使编织-嵌槽型金属橡胶的刚度升高,并使其线性阶段缩短;厚度对材料线性阶段的刚度和范围影响不大,而厚度的增加会降低材料在硬化阶段的刚度。

The fabrication technology of knitted-dapped metal rubber was introduced. The comparison of the static characteristic of knitted-dapped metal rubber with the ordinary one was made by carrying out the compression tests.The effect of the thickness and density on the compression deformation of knitted-dapped metal rubber was also studied. The results showed that knitted-dapped metal rubber was better than the ordinary metal rubber in many aspects,such as bearing capacity,range of vibration isolation and consistency of property. The stiffness of the knitted-dapped metal rubber increased and the linear range decreased with the increasing of density. The thickness hardly had any influence on the material's stiffness and the linear range,while the stiffness in the hardening stage would decreased with the increasing of thickness.
