| 摘 要： | 以自动毛坯缠绕工艺为支撑,基于实际材料、工艺参数,建立了空间弯曲螺旋线参数化方程、金属橡胶及毛坯的细观结构数值模型。通过数值模型,预测了构件的成形压力、模具摩擦力、模具应力、构件成形尺寸、回弹量、固相体积分数、接触点数、材料细观结构和组织分布等特性,预测结果与实验结果吻合良好。数值模型具有明确的物理意义和良好的可靠性,对于金属橡胶的制备具有较强的指导作用,为金属橡胶的细观尺度研究提供了途径。

| Abstract: | Space winding helix parametric equation, metal rubber and its blank meso structure numerical model were established with real 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 numerical model. Forecast results are coincident to experiment. 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. |

| Keywords: | metal rubber space winding helix press forming meso structure characteristic prediction |
