Abstract

Using cellular structure impact resistance, improving its poor stiffness shortcomings at the same time, this paper designed two types of ship vibration isolation shock honeycomb base with positive Poisson’s ratio effect and negative Poisson’s ratio effect. By adjusting the stiffness of base’s upper and lower panels, inside and outside closure plates, we can adjust the base natural frequencies and vibration isolation performance. By keeping the weight of honeycomb core, studied the effect of the thickness and layers of cellular unit on base isolation performance and impact resistance. The varying curves of isolator stress, natural frequency, vibration level, vibration level difference versus cell wall thickness were obtained and proved that cellular base has good impact resistance isolation and negative Poisson’s ratio has better performance.
