3-D Finite Element Analysis on Dynamic Response and Influence Parameters of High-speed Railway Rail-subgrade System
With the rapid development of the national economy, the construction of China Railway of High-speed has been comprehensively launched. During the period of the eleventh five-year plan, by constructing high-speed passenger dedicated railway, developing intercity passenger railway and upgrading the existing line, China will preliminarily form the express traveler network connecting the large and medium [...]
Research on Dynamic Response of High Rock Slope and Its Application
The ways to analyze dynamic stability problem of rock slope can be classified as pseudo-static methods and numerical simulation methods. Although the achievements of Pseudo-static methods are abundant and theoretical systems matured, it still has many obvious defects. Meanwhile, it became a researching obstacle that aroused many attentions of the scholars because people using dynamic [...]
Experimental Study of Dynamic Per-Formance of Small Passive Direct Methanol Fuel Cells
Fuel cells are the devices which continually convert the chemical energy of the fuel and oxidant into electrical energy through the electrochemical reaction directly. Because of their environmental compatibility and high efficiency, fuel cells have drawn increasing attention from governments and enterprises all over the world. Direct methanol fuel cells (DMFCs) have the advantages of [...]

Dynamic Analysis and Simulation of the Automotive Air Compressor’s Crank-Rod Mechanism
Crankshaft is one of the key components of piston compressor, which endures complex and alternating load, so it has complex dynamic characteristics and impacts compressor’s reliability and life directly. Therefore, it has important practical significance to analyze the crankshaft from the theoretical and practical point of view. The simplified method of traditional design and analysis [...]
An Analysis on Dynamic Response and Parameter of the Slab Ballastless Track of the High Speed Railway Subgrade
Tracing the process of the hundred year’s development of the railway, the deadweight of the train has almost increased by ten times, and the speed has improved by more than then times. For keeping abreast of the new century and situation, the construction of the high speed railway has been placed on the schedule. Because [...]
Study on the Dynamic Inverse-Analysis of Flexible Pavement Layer Modulus
There have been many achievements on pavements structure performance evaluation by using the data measured with FWD since FWD was used in pavement examination system in the end of 1970s in China. Back-calculate the modulus of pavement structure using the field measured deflection bowl data of FWD has been a hot research point now, and [...]
The Research on Wind-induced Response and Equivalent Wind Load of Tall Building
With the development of economy, the progress of science and technology, and the increment of the population in cities, tall buildings have been greatly developed in the last thirty years. The current status and future trends of this development make the wind-induced effects on tall buildings as one of the most important effects affecting the [...]
The Application of Polyurethane Injecting Method in the Asphalt Pavement Structure and the Anlysis of the Motion Response of This Application
Recently, good results have been achieved by using Polyurethane Injecting Method in the maintenance of highways at home and abroad, and some research has been done about the dynamical analogue of FWD and the dynamic response analysis of asphalt pavement structure under dynamic load, but there is few research about the dynamic response and the [...]
Research on Seismic Isolation Technology of Free-standing Equipments
In the Process of the earthquake, as the majority of valuable equipment has not taken seismic measures to avoid slipping, overturning, or collision, the equipment will be damaged or the accuracy of performance will decreased . Sometimes the control system will stop or malfunction,which will result in greater loss.The main contents of this paper is [...]
