本文研究了目前用于校准非整体式风洞测力天平的实验设计和回归模型。这种校准方法对于这类天平是必要的，因为它具有取决于所施加的力和力矩的符号的电响应。这种依赖性会导致响应面的不连续性，这不容易使用传统的响应面方法进行建模。目前推荐的校准模型的分析显示，导致相关的响应模型条款。替代建模方法进行了探讨，其功能正交或近正交的条款。
This research paper investigates current experimental designs and regression models for calibrating internal wind tunnel force balances of non-monolithic design. Such calibration methods are necessary for this class of balance because it has an electrical response that is dependent upon the sign of the applied forces and moments. This dependency gives rise to discontinuities in the response surfaces that are not easily modeled using traditional response surface methodologies. An analysis of current recommended calibration models is shown to lead to correlated response model terms. Alternative modeling methods are explored which feature orthogonal or near-orthogonal terms.
