摘要：

Two-roll bending with the elastic medium is an advanced technology for sheet metal forming which combines the principle of traditional roll bending with the advantage of stamping using elastic medium(polyurethane). The process principle of rotary shaping with the elastic medium (RSEM) is introduced, and the experiment investigation of RSEM has been carried out, in which the primary technique factors of RSEM are discussed. A new concept of converted modulus of elasticity of polyurethane E-e is put forward, and expressions of Ee is derived, by which the elastic medium can be selected reasonably. Moreover, the model of analysis of RSEM is built by finite element analysis software MARC, which has been applied successfully to simulate the whole process of workpiece forming and resilience. The result of the finite element analysis (FEA) are compared with experimental measurements, Simulation shows good agreement with measurements. The results of FEA are helpful to assign the value of the processing parameters of RSEM
