Study on Stowage System of Container Ship
Container vessel, As one of the three main formats of ship(Bulk carrier、container vessel、Oil tanker), has not only been needed greatly in the market, but is also a great advantage for our country, so it has been the major and very important format of ship we develop to make our county to be the greatest shipbuilding [...]
Strain-sensing Characteristic Research of Polymer Based Carbon Fiber Smart Layer
With support of NSFC(National Natural Science Foundation of China) Funding:smart concrete and its structure(program No:50238040) and the multi-field coupling mechanism and field diagnosis of carbon fiber smart layer (program No:10672128),aiming at healthy monitoring of large structure,we designed the polymer based carbon fiber smart layer to sense the deformation and damage,meanwhile made explorative theoretical analysis and [...]
Probability Analysis on Ultimate Load of Lattice Shell with Initial Installment Imperfection
Because of the influence of construction level,the lattice shell inevitable existes initial installment imperfection,and this shall lead to the reducing of ultimate load.Especially for single-layer reticulated shell structures,the ultimate load of the defect is more sensitive to the initial installation.For different defects,the sensitivity of the structure is different,the key factors found to control the error [...]
Research on the Metrological Properties Analysis and Simulation of Temperature Field of Thermostat Bath
Thermostat bath is environment temperature test equipment which provides aconstant temperature field used for instrumental verification. The techniqueperformance of the thermostat bath determined the quality of metrological verification.In this study, through experimental study of the metrological verification rules oforder the temperature of the thermostat bath temperature field equilibrium condition,which found some of the provisions of [...]
Experimental Research of Flat Plate CPL and Numerical Simulation for Evaporator
Space technology is one of the most popular and the fastest growing science in twenty-first century. Because of high-power and high heat flux electronic equipments widely used and space limitation on spacecrafts, traditional thermal control devices have been difficult to meet the requirements. In recent years, a sort of thermal control device (Capillary Pumped Loop) [...]
The Influence of Oil Supply Pressure to the Floating-ring Bearing’s Characteristics and Experimental Research
Hrdrostatic/hybrid journal floating ring bearings are mainly applied in high-speed rotating machines such as aviation engines, air-separation and high precision grinding machines. Investigations on the influence of oil pressure to the performance of bearing and on how to control the stability of bearing-rotor system by changing inner and outer oil film pressure has a significant [...]
