摘要
以锥齿轮零件为例,分析其精锻成形工艺。建立了有限元分析模型,通过锥齿轮精锻成形工艺的数值模拟,研究了锥齿轮成形过程中的材料变形行为、几何形状变化、载荷、应力和应变分布等。确定了精锻锥齿轮的成形工艺。将精密锻造理论、计算机辅助设计技术以及数值模拟技术结合起来,缩短了产品开发周期,提高了模具寿命,降低了生产成本。
The process of bevel gear was designed according to the structure characteristic of bevel gear. The FEM model of the precision forging process of bevel gear was established. The material plastic behavior, changed geometries, load and the distribution of the stress and strain were explored by finite element simulation. According to the simulation results, the process of bevel gear was determined. The theory of precision forging, CAD and technology of numerical simulation were integrated to shorten developing peri： od, prolong life-span of die and cut down the cost.
