Published: December 2012

Gears have been extensively employed in transmission machinery. Among the various and variant types of gears, helical gears have the characteristics of low vibration and low noise, and are especially apt for application in industrial machines. This study proposes to use mathematic geometric equations to compose the programming language via which point data are obtained and processed by Solid Works to complete the construction of the model. As for assembly error and stress analysis, the constructed model is then converted into ANSYS Workbench for implementing the stress analysis of the transmission under the condition of ideal assembly and of erroneous assembly. This study focuses on the impact of assembly error on the transmission in regard to the different pressure angles of the driver side of a helical gear with asymmetric teeth. The results show that the bigger the pressure angle of the driver side of the helical gear, the less stress during the transmission. Furthermore, the stress would increase when a minimum axial error is set. In conclusion, assembly error will cause uneven stress distribution, resulting in reduced service life and other problems.

PAM-STAMP 2G offers a Die Compensation module, which is used to modify the die surface of thick freeform surface steel plate forming focused on springback defects. The approach based on iteratively comparing a target part shape with a numerical simulated part shape following forming and springback can be effective in reducing springback error.

Fatigue failure easily occurs in the weld seam of bogie frame, fatigue life prediction is very important. Based on the UIC615-4 (Motive power units- Bogies and running gear-Bogie frame structure strength tests ) and IIW standard (Recommendations for fatigue design standard of welded joints and components-IIW document XIII-1965-03/ XV-1127-03), fatigue test process of bogie frame is simulated by means of finite element method. Using Miner cumulative damage theory, on the basis of IIW welded joints S-N data, fatigue life of the welded frame is predicted, and the virtual fatigue test of welded frame is completed. During the phase of product design, virtual fatigue test technology can be used to evaluate the fatigue strength, which can find the weak part and improve product design quality.

Published: December 2012

The question of the anti-missile fragment produced by the Kinetic Kill Vehicle (KKV) intercepting the Tactical Ballistic Missile (TBM) is studied. It turns out the anti-missile fragment are composite outcome of the impact and explosion. By analysis the National Aeronautics and Space Administration (NASA) impact breakup model is suggested to calculate the fragment charac-teristic. The minimum mass threshold of effective fragment is deduced; the damages probability model that the debris cloud impacts the cooperative target is established based on Poisson distribu-tion. The simulation case indicates that the damage probability can achieve the 10-3 magnitude, and should attach importance to this threat.

In this paper, mainly according to the selection of sugar cane seeds and the quality requirements for cutting, we design a cutting mechanism not only to cut off the sugar cane , but also can ensure the cutting sugarcane planting to achieve the agronomic requirements for sugar cane . The institution's overall ideas are as follows: first,measure different kinds of sugar cane planting in different cutting force and cutting speed in case of broken head.After preliminary analysis,gain cutting force,cutting speed ,the diameter of sugar cane ,the species of sugar cane ,cutting blade edge angle, cutting angle and cutting mode correlation.Then select the power transfer device and the working parts of the disk and blade according to the obtained data.Last design drive of belt wheel, drive shaft, bearing type, bearing cover through calculation and checking.The successful design and development of the institution of sugar cane cutting mechanism will be able to greatly reduce the labor intensity and production costs in the process of sugarcane planting.

To make up the Control Words (CW) share and deployment cost-ineffective defects in traditional pay-TV services, an advanced security conditional access system and its implementation are introduced in this paper. It is based on STB with a secure GSM module, where iterative key encryption for CW and wireless transmission for identity authentication and entitlement data are used, and it can prevent the piracy of pay-TV and protect the profit of pay-TV operator. The system is proved to be highly secure, easily deployed and cost-effective by experimentation in lab and now in mass production for broadcasters and operators

Published: December 2012

GH3230 is a new type of superalloy,it is the first study about it. This paper studied the high temperature mechanical properties of the GH3230 base metal and argon-arc welding joints by high temperature tensile test,high temperature creep test and SEM analyses. The results showed thatthe ultimate tensile strength of GH3230 argon-arc welding joints is about 85.6% of that of base metal under the same conditions. In the high temperature creep test, GH3230 argon-arc welding joints had a longer creep life than that of base metal. Both GH3230 base metal and argon-arc welding joints showed a ductile fracture. High temperature tensile fracture is cavities fracture and high temperature creep fracture is intergranular fracture. The deformation of GH3230 argon-arc welding joints is much more uniformited and smaller than that of base material, and GH3230 argon-arc welding joints has less cracks.

Authors: Lei Deng Sheng , Huang Xiao Liang , Xu Chun Bi
Published: December 2012

It is a special modality of solid-fluid conduit flow for the sand transporting procedure in wellbore. Under the action of heavy oil, because of the difference of the borehole location, the transporting mechanic of sand is not the same. For the vertical wellbore, sand particles are mainly dominated by the drag forces and carried out of the hole; however, for the horizontal wellbore, sand particles are under complex forces and show different flow state. In different flow state, the sand particles are controlled by different forces, the heavy oil’s sand transporting capacity is changed. This paper begins with the analysis of the stress of the sand particles, and deeply analyses the vertical and horizontal wellbore, the stress of sand particles in the heavy oil’s sand mixing flow procedure, and then study the heavy oil’s sand transporting capacity.
