Numerical Simulation on Efficient Spinning Technology Based on Multi-Point Adjusting Principle

Abstract:

In order to realize high efficiency and flexible manufacturing for rotary surfaces, efficient spinning technology (EST) is researched. It is the combination of multi-point forming and traditional spinning. Principle of EST is described, traditional spinning method is compared with it, 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; equivalent stress in sheet metal’s center region and bendable rollers active region exceeds yield stress, and plastic deformation is generated; experimental result accords with simulation result. Feasibility of EST is validated by simulation and experimental results.
