| 摘 要： | 帘线－橡胶复合材料力学性能的精确测定是轮胎有限元分析成功应用的关键。采用云纹技术直接测量应变来确定这些力学性能较为适宜。本文应用云纹法对不同体积分数的单层钢丝帘线－橡胶复合材料力学性能进行了测量研究，并与哈尔平－蔡等公式的理论计算值作了对比讨论。发现云纹法测得试验结果与帘线一橡胶复合层表面材料的力学性能有关。此外对试样没长不同长宽比也进行了对比，表明试样尺寸在本文中所取的长、宽比范围内对帘线－橡胶复合材料性能影响不大。

| Abstract: | AccuratC deterdrination of mechanical properties of cord-rubbercoplnosites is a key to successful finite element analysis of tires. Deterrnination ofthese properties from strains direCtly measured by the Moire technique is moreappropriate. In ibis Work in-plane extffoional meChanical properties of single-plysteel cord-rubber composites with different volumes of fractions of cord have been detennined by Moire method. Corresponding values from Halpin-Tsai and sallarequations are compared With experimental data. The results obtained by Moire methodrepresed meChanical properties of sauce material of steel cord -rubber composites. Inaddition, the meChanical properties of the steel cord- rubber composites were not affected by the samPle size as samples with different ratios of length to Width were used inthe measurement for comparison. |
