The Finite Element Analysis on the Seepage of Dock and the Stress of Dock Floor
The level differences of groundwater and great hydraulic gradient must be formed when drainage system is used to drain the seepage flow of a dry dock around which there are high groundwater and river levels. At the same time, the seepage under floor will produce uplifting pressure under the dock floor. The dock floor will [...]
The Study on Dynamic Performance of Partial Double Layer Reticulated Shell
There are some special properties of the reticulated shell structures,such as admissibility of reasonable,handsome in appearance and constructed facilitate,so they are more and more widely used in sports centers,exhibitions hall space and other large civil and industrial construction.The single-layer reticulated shell combined with the double-layer reticulated shell to form the partial double-layer reticulated shells,they have [...]
Ultra-large Indirect Air-cooled Structure System Temperature Stress Analysis and Study
In China the development of air-cooled technology of power plants has come through from small to large,from juvenility to relative maturity,and the application of indirect air-cooled technology has made a significant progress in power plants.However, with the emergence of air-cooled large units,the height of some air-cooled towers has exceeded the scope of application of conventional [...]
Finite Element Intensity Analysis of the KLQ-type Heat Exchanger with Non-standard Shell Flange
Tube-and-Shell heat exchanger is the equipment to exchange heat. It is widely used in chemical,oil,electricity,light industry,metallurgy,nuclear energy,ship building, aviation, heating and other industial.Especially in the petroleum refining and chemical processing equipment,it takes an extremely important position. With the continuous expansion of production scale and modern production technology,heat exchanger technology must meet special circumstances and conditions [...]
Modeling and Simulation for Bending Stress Analysis of Transmission Gears
Automobile transmission is the key to automotive driveline assembly, and the transmission gear is a key component of transmission. Gear’s carrying capacity will affect the quality of the entire transmission system, thus affecting the overall performance of motor vehicles. Therefore, checking the intensity of transmission gear has great significance. Practice has shown that tooth bending [...]
Research on the Landing Dynamic Performance for a Certain Type of Aircraft Landing Gear
The current using situation of a certain type of aircraft is universally accessing to the mid and late life of the design, so malfunctions began to increase, for example, a lot of structural wear and tear, fatigue, cracks and other situations. In my department, there were two plane Rocker arm cracks of a certain type [...]
Analysis on Dynamic Characteristics of Semi-Supported CFST Arch Bridge
As a newly-developing bridge style, concrete filled steel tubular (CFST) archbridge has been widely applied and rapidly developed in our country, for its own merits and can make agreement with the factual situation of bridge engineering in China. Because a large number of CFST arch bridge have been or under constructed in our country, the [...]
The Toughness Test Studies of Fiber Concretes in the Wet Joint of Continuous Bridge Erected as Simple-supported Beam
Along with the urban development and the construction,it asked a higher request to the bridge construction’s speed,and presented many forms of continuous bridge erected as simple-supported beam.After using the wet joint design the continuous bridge erected as simple-supported beam,has caused two kind of structural styles:The first kind is the bridge floor continuously or the floorboard [...]
Analysis on Dynamics Characteristics and Earthquake Response of Long-Span Cable Stayed Bridge
Cable-stayed bridge because of its cross capacity,the efficient structure and modern bridge engineering is in the fastest growing,and is the most competitive one of the bridge types.Recent years,the bridge is taking into account in the economic and aesthetic factors,demi-tower,tower cable-stayed bridge with its economic,aesthetic, etc.,there have been a tendency to be heated up,the bridge-outside of [...]
Finite Element Analysis and Research of Side Impact Performance of a Minibus Door
With the rising of automobile possession in our country, the traffic accident is becoming a big social problem. So the research is focus on the automotive passive safety. In July 2006, the regulation of side impact has carried out, which will promote the research of side impact.Strength of side door is specified in the side [...]
