工程所用的橡胶元件大多通过装配或者挤压工艺来获得预压缩应力,而这会使得橡胶元件在承载过程中表现出明显的Mullins效应,为此,笔者详细探讨了橡胶材料的Mullins效应原理,以及Mullins参数对橡胶软化行为的影响规律,验证实例的分析与试验测试结果表明:在预应力程度非常剧烈的情况下,引入Mullins参数的分析结果能获得与实验测试相一致的结果,而这为研究及分析带预应力的橡胶元件提供了一种新的思路和方法。 Most of the rubber components used in the project get the pre-compressive stress through the assembly or extrusion process, which will make the rubber component show obvious Mullins effect in the process of bearing. Therefore, the author discusses in detail the Mullins effect principle of the rubber material, Mullins parameters influence on the softening behavior of rubber, the analysis and test results of the verification example show that the results of Mullins parameter analysis can get the same result with the experimental test under the condition of very prestressed degree, And analysis of prestressed rubber components provides a new way of thinking and methods.
