	Numerical simulation on efficient spinning technology based on multi-point adjusting principle (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Manufacturing Science and Engineering, ICMSE 2011, April 9, 2011 - April 11, 2011, Guilin, China Gong X. P. 收藏 \| 浏览/下载：49/0 \| 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
