Authors: Zhao Jing , Wong Pak Kin , Xu Tao , Deng Rui , Wei Cai Yang , Xie Zheng Chao
Published: March 2014

In view of the drawbacks of the traditional optimal methods in the suspension structure optimization, this paper elaborates a genetic algorithm (GA) based global optimal design so as to improve the vehicle performance. Firstly, an independent double wishbone air suspension (IDWAS) is constructed. After defining the linkage relation of the guide mechanism of the IDWAS, the model is verified followed with the parametric design. Furthermore, in consideration of the prescribed targets of the vehicle kinematics, the wheel alignment parameters (WAPs) are selected as the objectives of the optimal design of the vehicle kinematics. Apart from the kinematic analysis of the IDWAS, dynamic analysis before and after optimization as well as the traditional independent double wishbone suspension (TIDWS) are also conducted. Numerical results show that the changes of the WAPs are within a certain range and the guide mechanism follows the prescribed constraints. Simulation results show that the IDWAS is superior to the TIDWS, while the optimized IDWAS has a slight improvement as compared to the original IDWAS in dynamic performance of the suspension.

Authors: Wang Shu Sen , Liang Cheng Hao , Huang Nai Bao
Published: March 2014

The effects of Fe content on the corrosion behavior of Al-Zn-In-Mg-Ti-Si sacrificial anode were investigated by the microstructure observation and electrochemical measurements in order to improve the dissolution feature and electrochemical properties. The results show that the current efficiency of Al-5Zn-0.02In-1Mg-0.05Ti-0.12Si-0.1Fe (wt.%) alloy corroded uniformly reaches 93 % in seawater. It presents the property of lower resistance and higher capacitance. While the Fe content exceeds 0.1 wt.%, the resistance of active dissolution increases gradually. The current efficiency falls down obviously. The results indicate that the electrochemical properties and dissolution feature can be improved significantly by suppressing Fe content under 0.1 wt.% in Al-Zn-In-Mg-Ti-Si alloy.

Parameter variability, however, leads to performance asymmetry among the cores, degrading the energy efficiency of the system. Recently, voltage/frequency island (VFI) based designs are widely exploited on a multi-core platform for system energy optimization under variations. In this paper, a post-silicon energy optimization scheme is proposed targeting VFI-based 3-D multi-core SoCs. Design constraints on VFI, difference of communication energies between horizontal and vertical directions and unique thermal feature of the 3-D chip are totally considered. An energy efficient task mapping and scheduling algorithm is proposed, which seamlessly combines with dynamic voltage/frequency scaling to minimize the system energy under deadline and thermal constraints. Experimental results demonstrate that the effectiveness of the proposed scheme.

For considering the magnetic fields produced by the UHVDC transmission in our country which may have influence on human and communication equipment. This paper use ANSYS finite element software to modeling to analysis the regularity of distribution and order of magnitude of the magnetic fields produced by the UHVDC transmission. By comparing with the limitation of the correspond criteria. We can infer that the electromagnetic fields produced by the UHVDC transmission whether have influence on our environment and harmful to human.
Description of Semantic Web Service in Wind Power Plant Based on OWL-S
Authors: Wang Xin Ying
Published: March 2014

IEC 61400-25 is a series of international standards on communication of wind power plants. The service defined by information exchange models in wind power plants communicates through being mapped to web service. Web service is described by WSDL, but with the limitation of WSDL itself, web service can not realize the semantic description, the automatic discovery and composition of service. So semantic web service is introduced, the service is described by OWL-S to realize the interconnection of wind power plant hardware devices from different manufacturers, to facilitate the sharing and reuse of devices function and to realize the sharing of wind power plant knowledge in semantic level.

In the fuzzy evaluation process of the power quality, different membership function scan lead to different results, which affect the credibility of the evaluation. In order to avoid subjectivity of choosing membership function, a combined membership function based on the Variance-covariance optimized combination method is proposed. Firstly, five typical member-ship function is selected after the deeply analysis of the power quality data. Secondly, weights of each function are calculated by the variance-covariance optimized combination method, and then a combined membership function of general applicability is constructed according to the weights. Thirdly, the fuzzy evaluation is performed by using this combined membership function. Finally, an application of this combined membership function in the fuzzy evaluation of power quality of a power supply bureau shows that this function can improve credibility of three valuation result.

.Based on the formulation of conventional operational rule, a scenario clustering method for extracting TTC operational rules of transmission corridors with the integration of wind power is presented in more detail. The scenario clustering for the network state is obtained on the basis of the output-load level of wind farm; in a certain scenario, the rules can be utilized to provide decision support for the dispatchers. The formation of the rule is proposed by using the data mining techniques, consisting of sample generation, feature selection and rule extraction. IEEE-RTS79 system simulation results indicate that the relationship between operation state and TTC can be better reflected by the dispatching information based on the scenario clustering.

Using the equipment, YL-236 single chip microcomputer (SCM) control device installation and debugging training platform, used in the SCM event of the National Vocational Students Skills Competition (NVSSC) as hardware carrier, this paper researched the application method of real-time operating system (RTOS) in the implementation of the SCM Skills Competition task, and apply the real-time multitasking operating system (RTMOS), RTX51, in the 8-bit 51 SCM. That allows switch of circulation tasks, supports the signal transmission, utilizes the interrupt function in parallel, and has very small demand for RAM. That makes whole SCM task to develop much easier and more convenient, and enhances the real-time performance and reliability of the SCM Skills Competition task at the same time.

Compared with crank-slider mechanism, the elbow-bar mechanism has some better dynamic and kinematic (D&K) characteristics for transmitting movement and force as the ultimate output component in mechanical press. The relations of the position, speed and acceleration of the driving and driven components, as the D&K characteristics of crank-slider mechanism, are quite important for analysis and design of the transmission mechanism and its components. All D&K characteristics of each components are established by analytical method, then the numerical simulation is carried out on the base of analytical euqations.

The verification test method on DTS system for power cable conductor-temperature calculation accuracy is described in this paper. The DTS temperature measure accuracy and positional accuracy are tests firstly. During the test a power cable laying in tunnel and applying different load currents ,the conductor-temperature measured value and the DTS system calculated value were compared. Testing process are employs the T-type thermocouple for conductor-temperature measure. DTS system calculates the conductor-temperature according to load current, over-sheath temperature etc. The difference between measured and calculated value were analyzed and compared, that was used for verify the accuracy of the power cable conductor temperature calculated by the DTS system.
