反共振理论在减振技术中的应用

Application of Antiresonance Theory to Shock-Absorption

提出了一种新型动力减振器──多自由度动力减振器，在不增加弹簧相对变形的条件下，可以大幅度减少动力减振器的总质量．阐述了无阻尼多自由度动力减振器的原理及其质量、刚度分布对该减振器总质量的影响．

A new dynamic absorber with multiple degrees of freedom (DAMDOF) was developed forshock absorption. Its gross weight can be reduced to a considerable extent under conditions that no additionaldeformation is applied to the springs used. The operation principle of such a damp-free dynamic absorber withmultiple degrees of freedom and the influences of its mass and stiffness distributions on gross weight are discussed.
