根据古布金塑性变形最小阻力定律首次推导出展宽率的计算公式,并建立了在各种锤砧下锻造时,展宽量的计算方法和计算公式,首次解决了塑性变形最小阻力定律的定量计算问题。经铅模拟试件和生产件的实际验证,其计算精度满足工业生产的要求。对于选择合理的坯料、设计合理的工艺、提高锻件生产率和锻件缺陷的修复等提供了依据。
According to the law of least resistance to plastic deformation of old cloth, the calculation formula of broadening rate was deduced for the first time and the calculation method and calculation formula of broadening amount under forging of various kinds of hammer anvils were established. For the first time, the quantitative calculation of the law of least resistance to plastic deformation . The simulation of lead specimens and production of the actual verification, the calculation accuracy to meet the requirements of industrial production. For the selection of a reasonable blank, design a reasonable process, improve the productivity of forgings and forgings repair provides the basis for such defects.
