    Notes: A microwave proton source for sealed-tube neutron generator has been built in the radiation Technology Institute of Northeast Normal University. The plasma resonance chamber is made of 95%Al2O3 ceramic material. The microwave absorption as a function of the magnetic field and the pressure is studied. The microwave absorption efficiencies, (Pi−Pr)/Pi are more than 90% when the magnetic field at the microwave windows is 0.095 T and incident microwave power is 300–500 W, at the same time, the impedance between the microwave circuit and the plasma source is well matched. Two-grid multi-hole extraction electrodes are employed to extract ion. The maximum proton current of 30 mA is obtained when the extraction voltage is 5.4 KV and the incident microwave power is 300 W. © 2001 American Institute of Physics.

    Notes: Box-like components are the component class with the complexity in structure and shape,and required premium quality on the machined surfaces, and with difficulty in design andmanufacturing. In Euclid Space, a 3D modeling with collection of feature information based mainlyon the CSG fundamental geometric element method and topological relationship was presented,with fundamental geometric element set, the topological relationship tree and datum system offundamental geometric elements, and Boolean operations and linking, for CSG modeling ofcommon box-like components. Details were also given to the study and construction of 9 modulesfor feature information collection. CSG modeling and collection of feature information of abase-box of reduction unit were put forward, as an example. The initial application of the systemhas shown that it was of simplicity, intuition, and effectiveness, with plenty feature pieces of featureinformation. It is satisfactory to design digitally even more complicated box-like components, andbuild up the information base for the following digital engineering with the current system

    Notes: Research on the mechanism of vibration cutting was carried out by analyzing the process ofvibration cutting and comparing the model of vibration cutting and conventional cutting. Proper speedcoefficient k can help to reduce the average cutting force while increase the cutting efficiencyaccording to the velocity and acceleration equation of vibration tool. Dynamic model of conventionalcutting and vibration cutting were built respectively. Compared with conventional cutting, it’s easier forvibration cutting to realize productivity gain, high machining accuracy and good surface finish

    Application of Wavelet Analysis in the Virtual Measurement of Roundness/Cylindricalness for Shaft-Like Components (2008)

    Notes: Wavelet analysis was applied to detect the greatest deviation from the perfect circle forthe roundness and cylindricalness of shaft-like components in the virtual manufacturing engineering.Based on the concepts of the roundness and cylindricalness, the least square method was adoptedinto the determination of the reference—the least square circle from which the deviation wascalculated. In order to obtain the extremum of the errors, wavelet transform was carried out withbinary wavelet from the time domain to frequency domain. A virtual probe was used to have thesignals for the measured point by using WTnode_gettranslation() function. The accuracy of themeasurement depends, to a large extent, on the length of individual step along the axis and thedensity of the measured points on the sections. Experiments have shown that the measuringprocessing was time-saving and the results from the wavelet analysis were much reliable

    Notes: Intensive processing for meat requires security, reliability, and efficiency, dreadfullydemanding the automation of the process. A newly mold system was optimum-designed with threerevolving positions for automated sticking in the material feeding, compression, and productknockout.The ratio of compression was taken with values in the range of 15-25% for the perfectshape and stringing rate. Surfaces of the mold were designed with mathematical planning of SUMTpenalty function, and referent parameter values were obtained. Final decision was chosen from thenine designs, reaching the requirements that the contours of the mold on the section was sodesigned that it gained a closed figure approaching a circle, with the ratio of long and short axelsbeing about unit. The curves were simple and few, and faired. Virtual and physical experimentshave shown that the mold design is of feasibility, and with the current study the difficult problemshave been solved of productivity, stringing rate, and automation of the meat strings, setting up thetechnical basis for the transformation of the production patterns from the conventionallabor-concentration to the modern technique-concentration in intensive meat processing industry
