P. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 In order to realize high efficiency and flexible manufacturing for rotary surfaces  equivalent stress in sheet metal's center region and bendable rollers active region exceeds yield stress  efficient spinning technology (EST) is researched. It is the combination of multi-point forming and traditional spinning. Principle of EST is described  and plastic deformation is generated  traditional spinning method is compared with it  experimental result accords with simulation result. Feasibility of EST is validated by simulation and experimental results. (2011) Trans Tech Publications.  and characteristics of it are analyzed. Finite element analysis (FEA) model of disc-shape part is established  EST process is analyzed  equivalent stress and plastic strain distributions are analyzed. EST equipment is developed  and the experiments are made. Results indicate: EST process consists of four stages   Pre-process technique study of a high performance remote image sensor structural Finite Element Analysis (EI CONFERENCE) 会议论文  OAI收割 2010 2nd International Conference on Computer Engineering and Technology, ICCET 2010, April 16, 2010 - April 18, 2010, Chengdu, China 作者:  Zhang L.;  Xu Y.-S.;  Zhang L. 收藏  |  浏览/下载：31/0  |  提交时间：2013/03/25 High precision structural Finite Element Analysis (FEA) results are required in the development of a remote image sensor. HperMesh and MSC. Nastran are employed in the image sensor structural FEA. This paper discusses some technical issues about the Finite Element (FE) modeling of the image sensor. In order to obtain authentic analysis results  the part-to-whole handling schema  i.e. handling method and research work is implemented in a small part of the model firstly and a revised method is used in the whole structural in succession  has been proposed. Some emphasis is mainly put on the FE handling of bolted joint  bearing and inter-element connection. The interface handling methods  such as CBEAM plus partial MPC bolted joint model  hybrid element bearing model and RBE3 beam-to-solid connection  have been produced and successfully implemented in the image sensor structural FEA. 2010 IEEE.
