摘要:
为了研究在高湿度紫外线辐照环境下橡胶材料及橡胶支座力学性能的变化规律,对橡胶材料进行了紫外老化试验,并基于试验结果和Neo-Hookean模型,通过有限元模拟探讨了紫外老化时间对橡胶支座压缩弹性模量的影响。结果表明,随着紫外老化时间的增加,橡胶材料的拉伸强度整体呈现下降趋势,但在老化42 d时出现小幅增大;扯断伸长率表现出相同趋势,其中在老化28~90 d区间内的变化较小;压缩弹性模量越来越大,材料硬度越来越高。紫外老化对橡胶支座压缩弹性模量的影响并不明显,随其增加压缩弹性模量总体是先增大后减小。
Abstract:
In order to investigate the mechanical property alterations of rubber materials and rubber bearings exposed to high-humidity ultraviolet (UV) irradiation, UV aging experiments were conducted. Based on the experimental data and Neo-Hookean model, the effect of UV aging time on compression elastic modulus of rubber bearings was analyzed through finite element simulation. The results showed that with increase of UV aging time, the overall tensile strength of the rubber material showed a decreasing trend, but a slight increase occurred at 42 d of aging. The elongation at break showed the same trend, with relatively small changed within the aging range of 28-90 d. The compression elastic modulus increased, which indicated the material hardness was getting higher. The effect of UV aging on the compression elastic modulus of rubber bea-rings was not significant, and as it increased, the compression elastic modulus generally increased first and then decreased.
