前言在弹性系统中,弹性支承除了金属弹簧外,尚有橡胶弹簧。它除了具有良好的减振、隔音和缓冲效果外,还有下列不可代替的优点: (1)橡胶弹簧的形状和尺寸能自由选择、调整,容易满足多向刚度和强度的要求; (2)有适当的阻尼,有利于越过共振区,能衰减高频振动和噪音,因而大为改善工作 Preface In the elastic system, the elastic support besides the metal spring, there is a rubber spring. In addition to its good damping, noise and damping effects, it also has the following irreplaceable advantages: (1) the shape and size of the rubber spring can be freely selected, adjusted, and easily meet the requirements of multi-direction stiffness and strength; (2) With proper dampening, it helps to cross the resonance zone and dampen high frequency vibration and noise, thus greatly improving the work
