Authors: Gao Hao , Lan Jian , Hua Lin
Published: June 2014

Bipolar plate is the key component of proton exchange membrane (PEM) fuel cell and represents a significant part of the overall cost and the total weight in a fuel cell stack. Many research have been done on the manufacturing methods of bipolar plate, among which stamping is very popular. With the increasing of the channel number and complexity, its dimensional error caused by sprinkback will change a lot, even under the same forming process. And the risk of crack is also different. These all impact the quality of bipolar plate. In order to predict deformation of channels and the plate’s quality, the displacement along X-axis, the strain and stress state, and the displacement along Z-axis are measured. The results show that 1) the risk of crack increases with the increasing of channel number; 2) the springbacks increase with the increasing of channel number; 3) the most dangerous point locates on the right internal fillet of the plate’s last section.

Authors: Xin Chun Lei , Gao Bo
Published: June 2014

Although underground structures have stronger aseismic performance than ground structures, seismic disasters of mountain tunnels were fairly conspicuous in Wenchuan Great Earthquake. On the basis of seismic disaster analysis, a composite lining designfor tunnel structures across active fault was put forward. Three-dimensional numerical simulation method was used to analyze aseismic and damping effect of this structure. The results show that: (1)After setting aseismic and damping structure, the maximum internal forces value in lining the pattern of internal forces will not change. (2)Aseismic and damping structure setting can directly reduce the bending moment value and increase the axial force and stress force value in lining structure. (3) Relative to aseismic and damping structure, grouting region around damping layer can ameliorate internal force condition in lining structure and improve the effect of aseismic and damping structure. The above research results contribute to provide reference for seismic fortification of tunnel structures across active faults.

Authors: Su Yu Jie , Wu Rui
Published: June 2014

As a effective stimulation, hydraulic fracturing was commonly used in the mining process of complicated low permeability reservoirs, especially in horizontal shale gas wells more widely. In this paper, we establish the BP (Back Propagation) neural network based on MIV (Mean Impact Value) which is different from traditional BP neural network. We choose the independent variables of training set, plus or minus a certain percentages. Measured by the absolute size of MIV value and analyze the changes of MIV value, we identify the main factors in hydraulic fracturing. Combined qualitative analysis with quantitative calculation, the hydraulic fracturing evaluation model was established. Compared with the traditional BP neural network, the evaluation model shows a high precision, and good stability. Above all, we succeed in achieving a rapid, objective and impartial productivity prediction after hydraulic fracturing in complicated low permeability reservoirs. So in the future, this new hydraulic fracturing evaluation model is about to having abroad applications in the field of hydraulic fracturing.

To find out the influence of particle shape on the force situation and sampling efficiency of the drilling tool, the discrete element method is employed to build the lunar regolith model and simulate the interaction between soil and drilling tool. A three-dimensional contact model is introduced to represent the impact between particles. To make sure the validity of the model, a triaxial-test is conducted to optimize the micro-parameters of the model. Then, the model is employed to the simulation of drilling process. From the computational simulation results, conclusions can be made: the particle shape will change the interlocking between particles, and the strip particles have the largest interlocking which makes the force situation largest and the sampling efficiency smallest.

The fault diagnosis of wind turbines is difficult because of the wind speed changing. To solve this problem, a method designated as Hilbert space feature entropy is proposed. The information entropy based on HHT is used to describe the wind turbine bearing vibration signal under different wind speeds. Using this method to analysis the fault of the D70 type wind turbine bearings, which proved that this method can effectively identify the fault of wind turbine bearing under different wind speed . Thus the method can be used as index and basis of the fault diagnosis of wind turbine bearing.

Mean Shift algorithm basedon floating point arithmetic calculation is very difficult to be implemented onreal-time systems. Another problem is that the tracking window of Mean Shift isnot adaptive. In order to solve the problems above, an improved Mean Shiftwhich can be implemented on FPGA is presented. Firstly, Hardware/softwarepartitioning based on the complexity of the algorithm is determined theimplementation of SOPC. Secondly, A pipeline structure is employed for MeanShift algorithm to calculate and accumulate kernel function, shift vector andtarget area in a single clock cycle, and accuracy is above 99 percent. Finally,as floating point arithmetic is more time-consuming, custom floating-pointinstruction is added into CPU to improve the algorithm operation speed.Experimental results show that the presented method can adaptively updatetarget windows and track target in 4ms stably, which improve the efficiencyof program by 5 times.
