Authors: Yang Fu Sheng , Zhang Ming , Wei Ben Long , Lin Min Qun
Published: February 2014

Shenfu coal (SFC) was pulverized and modified with planetary ball mill. Maceral separation of the coal was performed by means of density gradient centrifuge in zinc chloride solution. Blends from low density polyethylene (LDPE) and parent coal powder, iron ions loaded coal powder, or floated maceral fractions were prepared in co-rotation twin-screw extruder. Pyrolysis characteristics were investigated based on differential scanning calorimetry (DSC) measurements, apparent activation energies were calculated according to Kissiger and Ozawa methods. It is found that chemical interaction between SFC and LDPE is attributed to their overlapped pyrolysis temperature regions, leading to instant and rapid propagation and termination of macromolecular chains produced in the co-pyrolysis. Iron ions loaded in the coal can facilitate formation of radicals with acceleration in chemical reaction rates. Thermal degradation of LDPE is rate-determining step in co-pyrolysis of the coal and the polyethylene. Maceral fraction floated in 1.25g·cm-3zinc chloride solution is more reactive with polyethylene due to its higher content in aliphatic hydrocarbon and hydrogen, playing a role of excellent hydrogen donor to LDPE in the co-pyrolysis.

Research on Performance of Two Real-Time Simulation Environments: RTWT and xPC Target
Authors: Bai Yan Hong , Liu Cong
Published: February 2014

RTWT (Real-Time Windows Target) and xPC Target are two developing environments based on Matlab/RTW for hardware-in-loop real-time simulation and rapid control prototype. Some error messages which lead to program stop often occur in their practical applications, such as CPU overload, buffer too small, and so on. In this paper, performance of the two simulation environments were studied by analyzing their working mechanism and conducting a lot of experiments, including signal data logging capability, sampling period and system stability. And the reasons which cause error running messages were analyzed. The following conclusions have been drawn. For RTWT data logging capability is not limited by buffer size because the data in buffer are saved to file in real-time during operating. While for xPC Target data logging capability is not limited by buffer size because the data in buffer are uploaded to the host computer and stored in file at the end of run. As long as the sampling period is slightly larger than the task execution time, xPC Target can run stably. RTWT can run stably only when the sampling period is far larger than the task execution time. The proposed conclusions can provide reference for selection between RTWT and xPC Target and their application.

Calculation of the Scattering Coefficient of Large Scale Periodic Structure
Authors: Wang Hai Tao , Zeng Xiang Yang , Liu Yan Shan
Published: February 2014

The periodic structure is common used in engineering to improve the sound diffusion in room acoustics. It usually has large dimensions and it is difficult to calculate the scattering coefficient based on its original scale. In order to represent the scattering coefficients of a large scale periodic structure by those of a smaller one, the relations of the scattering coefficients of the periodic structures with different dimensions are analyzed in this paper. At first, a BMM (Boundary Meshless Method) for calculating the scattering coefficient is derived. The scattering coefficients of the periodic structures which have different numbers of sub-structures are calculated and compared. The computation results of different sub-structure numbers show that the periodic structure with 15 sub-structures can represent the samples which have more sub-structures. In addition, it can be proved that the square samples can be represented by those of the small and rectangular ones which have the same numbers of sub-periods. These conclusions not only greatly enhance the computational efficiency, but also show good prospect for fast evaluation of the periodic structures in engineering applications.

Authors: Shen Mu Wen , Fan Kai Guo , Yang Jian Guo
Published: February 2014

The CNC milling machine is extensively used in manufacturing of the die and the box-type parts. As the increasing requirement of the mechanical products qualities, the components also need higher and higher precision. However, the cutting force induced error affects the machining accuracy of the machined parts seriously. Furthermore, accurate measurement of the cutting force in CNC machining is very difficult. To solve this problem, a motor current-based cutting force induced error detection and modeling method is proposed in this paper. The motor current is obtained from the window function of the Fanuc CNC system. The cutting force induced error model is established according to the least-square method. The motor current-based error model can implement the cutting force induced error fitting effectively, and the fitting accuracy ofX,Y, andZ-axis are 97%, 96%, and 84%, respectively.

Published: February 2014

Current steel structure design software cannot calculate sectional properties of user-defined section of cold-formed thin-wall steel accurately. Since the sectional properties data given by design code has been implanted into corresponding modules of these software and the software disregard the radian of corner of steel, erroneous results will be generated if the user-defined sectional size doesn't match the sectional size of the data file implanted. According to Green's theorem, the author derived precise formulas for sectional properties of arbitrary section and developed software for calculation based on Visual C++ platform. The software which can calculate exact solution of sectional properties of arbitrary section has been verified by comparing results from various methods. This software can be used independently as a calculating tool and the calculation module can be implanted into other steel structure design software to make calculation for sectional properties of arbitrary section possible.

Wire ropes are important instrument for erecting wire in the wild. Regular maintenance and cleaning can extend the service life of wire ropes and guarantee construction safe. So its quite necessary to develop a set of equipment for rope-cleaning. Rope decontamination is a critical process in rope cleaning and detecting, the purpose of which is to primarily clean dirt on the rope surface and gaps. By calculating and learning from experiences, we designed this decontamination unit which contains rough-cleaning unit and semi-fine-cleaning unit. This design can be used for ropes with different diameter and promise rope head going through smoothly, most of the dirt will be removed. This design has been in practice and has acquired excellent result.

Published: February 2014

The braking signal transmitter is a major component of the EBS. The structure and working principle of a braking signal transmitter were introduced. The test bed of the braking signal transmitter was designed and built. The static characteristics of the braking signal transmitter were obtained by analyzing the test data. The inflection points and the slope of each segment curve obtained by the bed test are basically identical to the static characteristic calibration curve. The pressure does not reach the maximum pressure of the static characteristic calibration curve because the gas source pressure does not reach the required test pressure. Keywords: Braking signal transmitter, EBS, static characteristics, bed test.
