Structural Analysis of the Composite Wind Blade Using Finite Element Method
Study on the method for structural design and analysis of the composite wind blade is always one of the hot social studies. It is of great significance to promote the effective use of green resources.In this thesis, the work done by the following:1) Came to understand the basic principles of aerodynamic design of the wind [...]
Design and Construction of Ballastless Track on Subgrade in Sui-yu Railway
Ballastless track has been studied and developed for many years in China, but the ballastless track suitable for passenger dedicated line is laid only on the experiment plot of bridge and tunnel, laying test has not yet been done on the test section, especially on the subgrade and turnout zone, the study of ballastless track [...]
Optimization Design and Research of 6-dof Rotation Platform with Redundant Motion
Platform for ship motion simulating is an experiment equipment which used to simulate ship’s motion in ocean such as rolling, pitching and yawing on the land. It can aim to short developing period, reduce experiment cost and improve the reliability and success rate, since all kinds of ship motion are simulated in the laboratory.First, the [...]
Design and Research on Gearbox for MW Wind Turbine
The rapid development of wind power industry lead to the prosperity of wind power equipment manufacturing industry.As the core component of wind turbine, the gearbox is received much concern from related industries and research institution both at home and abroad.However,due to the domestic research of gearbox for wind turbine starts late,technology is weak,especially in the [...]
Study on Structure Design and Control Methods of Permanent Magnet Biased Hybrid Magnetic Bearing
With the development of modern industry, a variety of demanding performance requirements of rotating machinery are putted forward. In the energy and chemical machinery, the rotation speed and accuracy require of the rotor are ever growing, and the gap of the rotor and stator as small as possible in pursuit of greater efficiency; while others [...]
Research on Methods of Modular Division of Hull Structure and Simulation of Modular Construction and Assembly Based on Modular Design
With the formation of modern shipbuilding mode and development of advanced manufacturing technology, modular shipbuilding technology has been recognized as an advanced stage of “Hull construction, outfitting and painting integration, regional shipbuilding technology”. The essence of modular shipbuilding technology lies on the two main features of modern shipbuilding technology– integration of design and manufacture and [...]
The Design of V-Shape Hull Non-Ballast Water Ship
Ship’s ballast water has caused serious ecological pollution, in order to solve this issue, scholars have put forth new concept of NOBS (Non-Ballast Water Ship). NOBS can meet the needs of the navigation performance in no or only a small amount of ballast water situation. There are three kinds of NOBS design: V-Shape Hull design, [...]
Design and Analysis for Seismic Behavior of Complex Connected Structure
Overhanging structures are the characteristic of upper part of figure which is bigger than the lower part, similarly the shrinking structure. They are also belong to the vertical irregular structures. Because of the vertical irregular of overhanging structures, it is will be reduce the structures’ redundanciments. So,it is have no sufficient of the line of [...]
The Structure Design, Construction Technology of Continuous Rigid-Frame Beam Bridges
Continuous rigid-frame beam bridges is a combination of beam and rigid frame bridge system, Continuous rigid-frame beam bridges is characterized by main beam continuous, pier beam consolidation, Not only maintained a continuous beam without joints, smooth traffic advantages, but also maintained a T-shaped rigid frame with no support, no need to convert the construction’s system [...]
Research on Loader for Closed Test-bed with Parallel Shaft Ipsilateral Transmission
The loader is a common load tool which is used in marine gearbox. Marine gearbox is tested in the form of closed test-bed on land. The purpose of this research topic is developing a loader which is matching with given test-bed and make a trial on it. Detect and analyse the static and dynamic parameters [...]
