| 研究水平力分散型橡胶支座胶料的配方优化、胶粘剂膜厚对胶料与钢板粘合性能的影响以及橡胶支座的水平极限剪切性能。结果表明：丁苯橡胶（SBR）与天然橡胶（NR）并用和促进剂CBS与DTDM并用可显著提高胶料的抗硫化返原性能和耐热性能，橡胶支座的胶料优化配方为NR/SBR（并用比为60/40） 100，炭黑N774 35，氧化锌 5，硬脂酸 1.5，环烷油 15，防老剂RD 2，防老剂4010NA 2，硫黄 1，促进剂CBS/DTDM（并用比为4/1） 5；胶粘剂底涂膜厚为10～15 μm、面涂膜厚为25～30 μm较适宜；试制的LNR 600水平力分散型橡胶支座在100%剪切位移、200%剪切位移、300%剪切位移、400%极限剪切位移条件下，水平刚度分别为0.91，0.85，0.85和0.96 kN·mm-1，水平刚度偏差均在±15%范围内，满足设计要求。 |

| The compound formula of the horizontal force spread type rubber bearing was optimized，and the effects of the adhesive film thickness on the adhesion between the compound and steel plate and the ultimate horizontal shear performance of the rubber bearing were studied.The results showed that the vulcanizing reversion resistance and heat resistance of the compound could be significantly improved by blending of styrene butadien rubber（SBR）/natural rubber（NR） and combination of accelerator CBS and
DTDM.The optimized formula of the rubber bearing compound was NR/SBR（blending ratio was 60/40）100，carbon black N774 35，zinc oxide 5，stearic acid 1.5，naphthenic oil 15，antioxidant RD 2，antioxidant 4010NA 2，sulfur 1，and accelerator CBS/DTDM（blending ratio was 4/1） 5. It was suitable that the primer coating adhesive film thickness was 10～15 μm，and surface coating adhesive film thickness was 25 ～ 30 μm. Under the conditions of 100% shear displacement，200% shear displacement，300% shear displacement and 400% ultimate shear displacement，the horizontal stiffness of the trial LNR 600 horizontal force spread type rubber bearing was 0.91，0.85，0.85 and 0.96 kN·mm-1 respectively，and all horizontal stiffness deviations were within ±15%，which met the design requirements. |
