Flow-Induced Vibration Fatigue Damage of A Pair of Flexible Cylinders in A Staggered Array

Flow-induced vibration (FIV) of a group of long,flexible cylinders involves a complex interaction between fluid and structures.Although a substantial number of studies have been devoted to assessing FIV response behaviours,fatigue damage features of stagg

Numerical Investigations on Hydrodynamic Performance of An Open Comb-Type Breakwater Under Medium Wa

The comb-type breakwater (CTB) has been proposed and investigated in recent years due to its advantages in terms of deep-water adaptability,material saving and water exchanges.All existing empirical formulae for CTBs have been so far restricted to the wat

Fluid-Structure Interaction of Two-Phase Flow Passing Through 90° Pipe Bend Under Slug Pattern Condi

Numerical simulations of evolution characteristics of slug flow across a 90° pipe bend have been carried out to study the fluid-structure interaction response induced by internal slug flow.The two-phase flow patterns and turbulence were modelled by using

基于专利分析的发射箱(筒)端盖技术研究

背景rn发射箱(筒)端盖是发射系统重要部件之一,随着技术发展,发射箱(筒)端盖经历了机械开盖、爆炸开盖和复合材料端盖.张艳等基于学术论文综述易碎盖研究进展,王岩等基于学术论文综述复合材料发射筒前盖研究进展,目前尚没有基于专利文献的发射箱(筒)端盖研究进展综述.本文基于专利文献分析发射箱(筒)端盖技术研究现状,为端盖研制与生产单位提供国内竞争情报,为国内发射系统总体单位选择端盖供应商提供参考,同时也为端盖研制、生产单位的知识产权布局提供参考.
