| 1 | Analysis of the Cross-Wedge Rolling Process of Toothed Shafts Made from 2618 Aluminium Alloy显示文摘The paper presents the results of a thermo-mechanical analysis of the rolling two stepped shafts.One of the shafts has a toothed step with skew teeth,while the other has a worm winding in the shape of a trapezoidal screw.The shape of the rolling tools resembles that of the tools used in the Roto-Flo rolling method;yet unlike in Roto-Flo,the shafts are hot-rolled and no centres are used to stabilize the position of the workpiece during the forming process.For the calculations made with use of the DEFORM-3D process simulation system it has been assumed that the rolled shafts are made from 2618 aluminium alloy.As a result of the calculations made,it has been found that the toothed stepped shafts can be formed in one pass by means of the cross rolling process.Additionally,the temperature and strain distribution in the rolled product have been determined as well as some data concerning the forces which are necessary for the rolling process have been obtained. | PATER Zbigniew GONTARZ Andrzej TOFIL Arkadiusz | 2011 | Journal of Shanghai Jiaotong university(Science)2011，16，2： | 14 |
| 2 | Cross-Wedge Rolling of Shafts With an Eccentric Step显示文摘A new concept for forming eccentric shafts on the basis of the cross-wedge rolling(CWR)process was presented.This concept was based on the application of special guides,which,by acting on a billet,lead to its controlled movement in the vertical direction.This movement made possible eccentric cutting of tools into the billet.FEM calculations and experimental rolling tests clearly confirmed the effectiveness of the proposed forming method. | Zbigniew Pater | 2011 | Journal of Iron and Steel Research(International)2011，18，6： | 3 |
| 3 | Census of Kuiper Comets-the TAOS Project显示文摘Cometary nuclei, the remnant icy bodies of planet formation, located at the outer edge of the solar system, are relatively poorly studied because of their small sizes and thus faintness. Thus far more than a hundred large members (size about 100 km) of this cometary population in the Kuiper belt have been identified. Smaller bodies (10 km) are much too faint to image directly and their number so far can only be extrapolated on theoretical grounds. The Taiwan-America Occultation Survey (TAOS) will conduct a census of the number of Kuiper belt objects down to a few km size by monitoring chance stellar occultations by these cometary nuclei. We will set up an array of small (50cm), wide-field (f/1 9) telescopes, each equipped with a 2K squared CCD camera, along a 7 km baseline in central Taiwan at an elevation above ~ 3000 m. The robot telescopes will operate in a coincidence mode, so the sequence and timing of any candidate occultation event can be recorded and distinguished against a false detection. The Lawrence Livermore National Laboratory, the National Central University, and the Academia Sinica, will each contribute one telescope system. Researchers from an international variety of institutes are also participating in the project. Our experiment provides the only means to study the cometary population in the small-sized end of the distrbution. A great number of scientific byproducts, notably variable stars, will also derive from the huge TAOS database, some 10, 000 giga-bytes worth of photometrical measuremements per year. | Wen Ping ChenOther TAOS team members: C.
