Abstract We apply integrated parameter and tolerance design (IPTD) to optimize the nominal values and tolerances of 10 geometric design variables of a centrifugal compressor based on a computational fluid dynamics simulator. The compressor quality is quantified by the conformance probabilities of three performance measures (PMs) and optimizing the simulator directly is time-consuming. Gaussian process (GP) emulators are constructed to predict the PMs. A conservative conformance probability estimator penalized by its standard deviation and an efficient method to compute it are developed to facilitate optimization. Eight tolerances are loosened and two are tightened. Design variable effects on quality are better understood.

基于复杂模拟器的离心压缩机综合参数与公差优化

摘要 我们基于计算流体动力学模拟器，应用集成参数和公差设计（IPTD）来优化离心压缩机的10个几何设计变量的标称值和公差。压缩机质量通过三种性能指标 (PM) 的符合概率进行量化，直接优化模拟器非常耗时。构建高斯过程 (GP) 仿真器来预测 PM。开发了一种受其标准偏差惩罚的保守一致性概率估计器和一种计算它的有效方法，以促进优化。八个公差被放松，两个被收紧。更好地理解设计变量对质量的影响。
