对金属丝网橡胶进行了静态压缩试验。利用控制变量法研究了压缩量、相对密度、金属丝丝径、丝材和承压面积对金属丝网橡胶压缩力学性能的影响,并对平均刚度和能量耗散系数随压缩量和相对密度的变化关系进行了研究。试验结果表明:随着压缩量的增加,金属丝网橡胶非线性力学特性逐渐增强;相对密度越大,金属丝网橡胶承压能力越强;金属丝的丝径和丝材主要影响金属丝网橡胶非线性阶段的力学特性,丝径越大,丝材越硬,承压能力越强;承压面积越大,金属丝网橡胶的承压和耗能性能越好;随着压缩量的增加,平均刚度增大,承压能力增强,能量耗散系数减小,减震性能降低;随着相对密度的增加,平均刚度和能量耗散系数均增大,承压能力和减震性能均增强。
The metal mesh rubber static compression test. The effects of compressive strength, relative density, wire diameter, wire and bearing area on the compressive mechanical properties of metal mesh rubber were investigated by using control variables method. The effects of compressive strength and relative density on average stiffness and energy dissipation coefficient Changes have been studied. The experimental results show that the non-linear mechanical properties of the metal mesh rubber increase with the increase of the compressive strength. The larger the relative density is, the stronger the pressure-bearing capacity of the metal mesh rubber is. The wire diameter and the wire mainly affect the metal mesh Rubber non-linear stage of the mechanical properties, the greater the wire diameter, the wire harder, the stronger the pressure capacity; pressure area is larger, the metal mesh rubber pressure and energy performance better; as the amount of compression increases , The average stiffness increases, the bearing capacity increases, the energy dissipation coefficient decreases, and the shock absorption performance decreases. As the relative density increases, the average stiffness and energy dissipation coefficient increase, and the bearing capacity and damping performance are enhanced .
