轮胎胶料力学性质的实验研究

测定了子午线轮胎胶料（胎冠胶、胎圈护胶、三角胶、内衬层胶、胎侧胶和钢丝覆胶）力学性质中的杨氏模量、泊松比和密度3个重要力学参数的实验数据，并对其进行了理论分析。结果发现，轮胎各部件胶料主要表现出橡胶的高弹性质，其各自的泊松比和密度相差很小，杨氏模量相差较大。;The Youngs modulus， Poissons ratio and density of rubber compounds in radial tire，such as crown，bead chafer，bead filler，inner liner，sidewall and extruded steel coating compounds were measured and analyzed.It was found that the compounds in variour tire components showed predominantly the high elasticity of rubber，their Poissons ratio and densities were close to each other，but their Youngs moduli were quite different
