| 摘 要： | 成功建立带TPS风洞测力试验技术的一个关键问题是确保试验数据具有足够的精度,必须精细地分配误差。为获得满足工程需要的高精度测力试验数据,给出一种基于计算机符号运算的子程序,完成不确定度计算过程中公式自动推导、计算。最后通过对TPS风洞试验数据精度的敏度分析,给出了某运输机在2.4m跨声速风洞TPS试验中各环节的误差分配要求。

| Abstract: | It is very crucial to obtain test data of high accuracy to the successful establishment of TPS testing technique. So delicate allocation of random error is required during wind tunnel testing. This paper introduces a symbolic-computation-based program that can complete the formula derivation and uncertainty computation automatically. On the basis of sensitivity analysis of the data accuracy, the scheme of random error allocation of the TPS testing of an air transport in 2.4m transonic wind tunnel is presented. |
