对回火和未回火圆盘形金属橡胶试件进行了疲劳加载试验。通过割线刚度和等效粘性阻尼系数两个疲劳损伤参数对金属橡胶材料的承载能力和阻尼耗能能力进行了分析。结果表明:回火处理有助于消除金属丝线的应力,稳定试件尺寸,可以在较大程度上提高其承载和耗能能力,并延长其疲劳寿命。 Tempering and non-tempering disk shaped metal rubber specimens were subjected to fatigue loading test. The carrying capacity and damping energy dissipation capacity of metal rubber were analyzed by two fatigue damage parameters including secant rigidity and equivalent viscous damping coefficient. The results show that tempering can help to eliminate the stress of wire and stabilize the size of specimen, which can greatly enhance its bearing and energy dissipation capacity and prolong its fatigue life.
