【Abstract】 There are many contact surfaces in ship’s equipments,whose dynamic transmission performance is the key in computation of equipment’s response under shock loading.In this article,the dynamic response of equipment with typical contact surfaces under shock loading was researched numerically and experimentally.The dynamic characters of the contact surface and the transmission characters of shock loading in the contact surface were also discussed.The research shows that the stiffness of the contact surface varies non-linearly during the shock process and the distribution of the acceleration is affected by the contact surface.The comparison between the experimental and computation results shows that the numerical method used in this article has engineering accuracy.更多还原
