摘　　要：对于结构非对称的框梁类复杂结构件的成形,提出了按照计算毛坯截面图和分模面轮廓进行坯料初步设计,以及分别评价型腔填充性能、应变均匀性和缺陷产生趋势的评价方法。并用所提出的方法对TA15钛合金承力框进行了坯料设计优化和试验验证。结果表明,所提出的方法能够有效地反映不同坯料对锻件成形过程的影响,获得了理想的成形效果。For the forming of the complex frame beam part with unsymmetrical structure, it is presented that preliminary design of blank is performed according to the calculation blank-sectional view and parting contour; the evaluation method of cavity filling performance, the strain uniformity and defect trends is carried out respectively. Blank design optimization and experimental verification of TA15 titanium alloy bearing frame were performed by using this method. The results show that the proposed method can effectively reflect the impact of different blanks on forming process of forgings. And ideal forming effect was obtained.
