研究了金属橡胶构件在不同方向的载荷作用下表现出来的各向异性,提出了用于分析金属橡胶材料内部结构的物理假设,并根据假设确定了各向异性研究的主要参数,然后通过实验研究进行了验证。实验结果表明,如果改变金属橡胶元件的相对高度,增加径向尺寸可以在很大范围内改变金属橡胶隔振器的径向刚度;要使金属橡胶隔振器的力学特性更近于线性,应让隔振器在径向范围内工作;如果隔振系统中含有多个承受压载荷的金属橡胶隔振器,则可以使其工作在与成型压力方向相垂直的方向。当相同结构和尺寸的钢元件和金属橡胶元件在承受剪切载荷作用时,这两种材料表现出了相同的刚度变化趋势。

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.
