【摘要】：通過對Mooney-Rivlin本構(gòu)和Ogden本構(gòu)進(jìn)行研究,得出2種典型超彈性本構(gòu)模型在輔助隔震橡膠支座設(shè)計分析中的適用性,并對2種本構(gòu)模型進(jìn)行隔震橡膠支座豎向剛度和水平剛度模擬。結(jié)果表明:工程應(yīng)變小于1.33時可選擇Mooney-Rivlin本構(gòu)模型;工程應(yīng)變在1.33與4之間可選擇Ogden本構(gòu)模型;Mooney-Rivlin本構(gòu)模擬隔震橡膠支座的豎向壓縮與Ogden本構(gòu)模擬隔震橡膠支座水平剪切剛度均與試驗結(jié)果吻合較好。
[Abstract]:Based on the study of Mooney-Rivlin constitutive model and Ogden constitutive model, the applicability of two typical hyperelastic constitutive models in the design and analysis of isolation rubber bearing is obtained. The vertical stiffness and horizontal stiffness of the rubber bearing are simulated. The results show that the Mooney-Rivlin constitutive model can be selected when the engineering strain is less than 1.33. Between 1. 33 and 4, the Ogden constitutive model can be chosen to simulate the vertical compression of the isolated rubber bearing and the horizontal shear stiffness of the Ogden constitutive model to simulate the isolation rubber bearing is in good agreement with the experimental results.
