Numerical Simulation Of Metal Rubber Press Forming

Space winding helix parametric equation and a meso structure numerical model for metal rubber as well as its blank were established with raw material and process parameters of product based on automatic blank twine technology. Forming force, mould friction force, mould stress, product size, springback value, solid phase volume fraction, contact point number, material meso structure and tissue distribution were predicted by the numerical model. Forecast results are coincident with the experiment. The numerical model is physically significant and reliable definitely. The model is directive for manufacture of metal rubber and makes it possible to research metal rubber in meso scale.
