隔振降噪用橡胶胶料及其制品的动态参数是决定振动与噪声控制中隔振度和降噪量的重要依据。本文从工程实用角度出发,对常用橡胶的动态特性加以阐述。具体涉及到胶料的静、动态弹性模数,隔振器等橡胶制品的静、动态刚度以及它们的动静比和阻尼。进而结合丁腈胶和天然胶胶料及其隔振器的试验实例加以论证。目的是对橡胶隔振器与其它橡胶制品的刚度和阻尼设计提供参考。
Vibration isolation and noise reduction with rubber compound and its dynamic parameters of the vibration and noise control is to determine the vibration isolation and noise reduction is an important basis. This article from the practical point of view, the dynamic characteristics of commonly used rubber to be described. Specifically related to the rubber static and dynamic modulus of elasticity, vibration isolators and other static and dynamic rubber products and their static and dynamic stiffness ratio and damping. And then combined with nitrile rubber and natural rubber compounds and vibration isolator test examples to be demonstrated. The purpose is to provide reference for the stiffness and damping design of rubber vibration isolators and other rubber products.
