摘要
为了降低制造过程中非确定性因素对航空发动机总体性能的影响,通过在设计阶段考虑高压涡轮性能的非确定性,构建鲁棒优化设计模型来优化总体性能的设计方案,使用蒙特卡洛仿真量化非确定性的影响,并开发了相应的全局优化算法进行求解.数值实验的结果验证了鲁棒设计模型的优势,与传统确定性设计方法相比,在高压涡轮性能非确定的情况下,鲁棒设计模型获得的方案能平均减少15.97％的总体性能离散程度,具有较优鲁棒性.
Abstract
In order to reduce the impact of uncertain factors in manufacturing on the overall performance of aero-engines,a robust design model was constructed by considering the uncertainty of high-pressure turbine performance in the design stage.Monte Carlo simulation was used in this model to quantify the effect of uncertainty.A global optimization algorithm was developed to solve the robust design model.Numerical results validated the advantages of the robust design model.Its optimal solution can reduce the variability of the engine performance by an average of 15.97％,which showed better robustness in uncertain environment than the solution obtained by generic deterministic design method.
