Vibration Analysis of Exhaust System and Its Optimization
Exhaust system is an important component of vehicle, its main fuction is to deal with the exhaust and reduce noise. In the exhaust system design, the power loss, noise, emission and other issuses have been widespread concerned, but its dynamics is not given sufficient attention. One end of the exhaust system is connected to the [...]
Research on Classified Validation of Complex Structure Model
Since the 1960′s, the technique of structural simulation has become the essential instrument in the industries of aviation, aerospace, automobile, civil engineer and so on. However, in most case, feature such as modal and shock response obtained with FEA does’t fit with those obtained with experiments. Because of limitation of model updating, even though we [...]
Research on Grinding of Carbon Fiber Reinforced Plastics Used for Aviation
An important direction of new materials is to develop new techniques of composition. Carbon fiber, which has a very outstanding performance, is one of reinforcing material in advanced composite materials. Carbon fiber reinforced plastics have been widely applied in artificial satellites, high-performance aircraft and so on as one material used in aviation and aerospace. However, [...]
Nonlinear Structural Dynamics Analysis and Optimization Design on Naval Gun Driver
As the needs of modern naval warfare and the development of science and technology, naval guns have to continuously improve the technical performance. The Driver is an important part of the gun feeding system, its reliability could ensure the reliability of the gun feeding system. For vibration and broken of parts, this thesis focuses on [...]
Structural Optimization Design of Health Care Robot Bath Based on Numerical Simulation of Flow Field
As China enter the aging society, the daily health care issues for the elderly become more prominent, especially bathing one of the most important daily care. Developing personal health care Robot, nursing labor intensity can be reduced, the quality of life of older persons can be improved, it is more and more important.Structural optimization design [...]
A Certain Type of Automobile Pillar Reinforcing Plate Welding Technology Development
The structure of the layer board has extensive application in automobile spare parts. It can achieve the demand of structure strength and the body lightweight goals. Because the factory have not a standard to evaluation the quality of solder joint, the materials and equipment also have affect of welding quality. There is a certain relationship [...]
Structural Stability Study for Large-Scale Shield Shaft
Deep excavation engineering is one of the hottest and most difficult problems in rock engineering at present. It is largely dependent on the determination of the support parameter to guarantee the stability of the foundation structure. If the values of support parameters are too large, although the stability of the structure can be guaranteed, it [...]
Optimum Design of Extra-high Voltage Steel Tower
In recent years, steel tower structure is used to build most towers with large load in developed countries for it has a better aerodynamic performance, mechanical isotropic, cross-section flexural stiffness and high pressure stability. Therefore, steel components are adopted to build the high-voltage transmission towers not only can reduce the tower wind load, but also [...]
