A semi-active shock isolation technology based on controllable damping is put forword to solve the problem that the shock isolation system must offer high shock isolation efficiency and small relative displacement at the same time when it is suffered from a shock with short duratio.

Parameter effects of the main controlled anisotropic layer on structural damping of alternately laminated damped structures;

Modal damping optimization for general damped structures;

The development history of the damping materials is retrospected and the research status of polymer,polymer composites and structure damping materials is summarized subsequently.

The structure damping is a non negative function.

Recently developed composite damping structures indicate that various damping requirements can be met through simple composition of several damping materials.

And several composite damping structures w ere introduced, and some analysis about their working mechanism were given.

We use restrained viscoelastic damping structure to reduce vibration in combination with sound absorption, insulation and suppression techniques for integrated control,and good result has been obtained in noise reduction.

Dynamic analysis of structural damping of solid roller and hollow roller

Influence of structural damping on stability of the rotor system

The structural damping composites that have not only high damping but also high strength and modulus will hold an extensive application future.
