| 摘 要： | 金属橡胶隔振器是由金属丝相互缠绕模压成型的,它具有隔振性能好、易制成各种形状、重量轻、刚度可调节等优点,因此,在舰船机械领域具有广泛的应用前景.文章根据金属环形隔振器弹性模量的计算方法,利用环形金属橡胶隔振器的弹性迟滞回线近似得到的平均刚度,推导出环形金属橡胶隔振器弹性模量的计算公式,并得到了实验验证.此外,本文还通过实验分析了金属橡胶隔振器各个参数对其隔振特性的影响,得出了一些有用的结论.

| Abstract: | Metal rubber(MR)isolator is made of twined metal wires through molding and pressing.It has several advantages such as efficient to reduce the vibration,easy to shape,lighter in weight and convenient to change stiffness.For these reasons,it has prospective applications in warships.Based on the method to calculate the elasticity modulus of a circular isolator,average stiffness is approximately computed from by considering the hysteresis loop of metal rubber.The derived formula to compute the elastic modulus f... |
