摘　　要：在机械特性曲线重采样过程中,针对传统插值方法所存在的不足之处和不适应性,提出了采用Akima插值方法来拟合各种机械特性曲线,并使用VC编程实现曲线在计算机上的拟合,拟合曲线很好地反应了原始曲线的真实性和一致性,试验结果表明使用Akima插值法所拟合的曲线真实性好、精度高、结果可靠,在机械自动化设计过程中,能很好地替代人工查图表的工作量。In the process of resampling mechanical characteristic curves, aiming at the disadvantage and inadaptability of traditional interpolation meth- ods, a method to fit various mechanical characteristic curves by using Akima interpolation was put forward, and the curves fitting was realized on the computer through VC programming. The fitted curves could well reflect the authenticity and consistency of original curves, which showed that the curves fitted by Akima interpolation had high authenticity and precision with reliable results. It could substitute the work of artificial lookup of the graphics and tables in the process of mechanical automation design reasonably well.
