Periodic porous structures have been gaining more and more attentions to many researchers because of their excellent mechanical properties such as lightweight,high strength,and multi-functional characteristics including vibration suppression and energy absorption.The research on the dynamic mechanical properties of lightweight porous structures and their filled hybrid or composite structures in recent years were reviewed in this paper,such as energy absorption and vibration.Firstly,the cells and structures forms of lightweight porous structures with obvious advantages in vibration damping and impact resistance were summarized.Secondly,in terms of energy absorption performance,the research results were concluded from three aspects:quasi-static loadings,impact loadings,and their applications.Thirdly,according to the vibration characteristics,the research work on vibration analysis,vibration suppression or isolation,and the applications of vibration characteristics was also introduced.Finally,future development directions were prospected,including dynamic mechanical model of porous structure based on additive manufacturing,fatigue and damage tolerance performance of porous structures,dynamic mechanical properties of porous structures under multiple fields and loadings,the design methods and performance characterization of porous structures under impact and vibration resistance,and the design methods of porous structure-material-function-integration for engineering applications and so on.
