摘要
以多孔材料理论为基础,建立金属橡胶结构的力与位移关系,通过空心圆柱形金属橡胶结构力与位移关系试验,验证形状因子对材料结构的力学性能的影响,并对试验数据进行拟合,得到力与位移关系模型中各项系数与形状因子的变化关系式以及各项系数与材料结构的高度、承载面积的变化关系式,从而实现了对由金属橡胶材料所组成的结构在密度一定、形状因子发生变化情况下的力与位移关系的预估。
On basis of porous material theory,a model of force-displacement relation is constructed for a metal-rubber structure.Through fitting data of static experiments on the structure of a hollow cylindrical metal-rubber,the relations between coefficients of force-displacement model and shape factors are obtained.The relations between coefficients and the height or the loaded area of the structure are also obtained.Further,effect of shape factor on mechanical characteristics of metal-rubber is proved.Ultimately,prediction for the force-displacement relation of the metal-rubber structure is realized when the density is given and the shape factor are changed.
