粘弹性阻尼结构用以抑制和减弱宽带随机振动和噪声环境下多自由度系统的结构共振响应,尤其对轻型的板、壳结构,是一种行之有效的方法,因此阻尼减振技术已成为振动和噪声控制的一个十分重要的研究内容。它将涉及到不少学科领域,但从工程实际运用角度讲,对于阻尼结构的参数选择、设计方法和步骤国外已进行了不少摸索,本文在此仅作简要介绍。 阻尼结构设计和减振或抗冲设计不同,它要包括各类结构中各个部件的几何参数,刚度特性,边界条件,温度工况、阻尼结构以及所采用阻尼材料的动态特性参数的选择与配合等
Viscoelastic damping structure is used to restrain and weaken the structural resonance response of multi-degree-of-freedom system under broadband random vibration and noise environment, especially for light-weight plate and shell structure, so damping damping technology has become Vibration and noise control of a very important research. It will involve a lot of disciplines, but from practical engineering point of view, for damping structure parameters, design methods and steps abroad have been a lot of groping, this article is only for a brief introduction. Damping structure design and damping or impact design is different, it should include the various components of various structures of the geometric parameters, stiffness characteristics, boundary conditions, temperature conditions, the damping structure and damping material used in the selection of the dynamic characteristics and parameters Wait
