Abstract :

High energy, high power and compact size batteries are demanded on the current market of battery applications. As battery has turned out to be one of the essential components in driving high energy-consuming products, the development of battery is greatly important. Battery Management System (BMS) has become a very important core technology to play the major roles in performing safety monitoring, and effective control and management of the battery pack to improve the service performance and reliability of the vehicle while it is running. In this paper, the Coulomb integral measurement method was adopted as a checking device to compute the battery capacity as it can be implemented on different battery types and has an average current measurement error rate of only 1%. While the general testing devices require the battery to go through a complete charging process, the integrated voltage measurement method has the advantage to effectively save the battery checking time. When a 3000mAh battery is used in checking its performance, the normal checking time of 155 minutes can be reduced to 45 minutes while using the checking method adopted by the method proposed in the paper.

Abstract :

A new model for the micro-indentation test used to determine the material properties for the soft tissue is proposed in the present study. Based on the basic theory of elasticity, mathematical models such as infinite beam and circular plate are often adopted to describe the geometric characteristics of soft tissue. Other than the conventional simulations, say beam and plate, the author proposed a two-dimensional model for the tissue structure, which permits a hollow cylindrical shell with internal spring support and axial surface loads as the modelling of soft tissue. Different with the previous two, the shell model consists of two coupled differential equations involving both the transverse and longitudinal deformations as its main quantities. The proposed mathematical model offers additional information about the behaviours of the soft tissue in the micro-indentation test; meanwhile, the effect of residual stresses on the soft tissue with respect to both the transverse and longitudinal deformations can be thoroughly examined. The result of the present study matches the result by the simple beam model as long as the transverse displacement is under consideration; however, it reveals different illustration with that conducted by circular plate model due to the intrinsic variation on the governing equations. The longitudinal displacement of the soft tissue behaviour during indentation test is additionally presented in the study and the effect is shown to be parabolic-like in the case of stress free, however, it becomes almost linear when the residual stress is taken into account, and soon reaches its asymptotic state as the stress increases.

Abstract :

Analysis model of the single metal sealing model was built by using ANSYS software. Under the conditions of high and low pressures, the effect on contact pressure of rotating and stationary ring by the incline angle of rotating ring were analyzed. The result shows that contact pressure of sealing faces of single metal seal is increased gradually from inner to external under low pressure, and contact pressure appears two side peak values and the middle mild distribution under high pressure condition. When the incline angle of tilted face of rotating ring is bigger, the contact pressure of sealing faces is more smaller and the distribution is more mild, sealing performance can be improved effectively.

Abstract :

A system is produced to convert railway vibration into electrical energy which can be use for house hold purpose and for signal lights on railway root. . The energy is converted with the help of   variable capacitor.  Micro electromechanical systems (MEMS) technology can also be used for this purpose. This is one of the most promising technologies. The relevant applications discussed in this article include vibration energy harvesting from railway vibrations, vehicles, transportations. The unique challenges and future scopes of large-scale railway vibration energy harvesting are also discussed.

Abstract :

Numerical method is used in the semiconductor industry for the analysis and design of metal organic chemical vapor deposition reactors. The most important issue needed for prediction of epitaxial thin film growth rates and uniformity is the chemistry mechanism occurring in the gas phase and at the surface. Three numerical mechanism models are presented for verifying the growth rate of the gallium nitride (GaN) mechanism, and their results are compared with the growth rate results of previous literature studies. In order to reduce the calculation time of numerical analysis in commercial software, a numerical procedure is performed for simplifying the complicated mechanism of an epitaxial thin-film process through rate of production analysis. All the solution results could be compared in one schematic diagram, and the differences among these three mechanisms are extremely pronounced in high temperatures. The most simplified mechanism can be used to predict the growth rate of a blue-LED process before an actual process begins and it can be easily calculated in a standard computer. This study provides a useful and a predictable mechanism for GaN thin film research in blue-LED process. More verification work is under way by our own experiments.
