摘要

提出一种气动载荷下航空发动机的传感器测点选择方法.基于航空发动机相似设计的单转子试验器有限元模型,建立气动载荷表征模型.提出响应计算方法,根据整机机匣表面响应来计算关于气动载荷的灵敏度.基于灵敏度分析结果,采用有效独立法,分析机匣表面测点的独立性.结合灵敏度与独立性,选择传感器布置最佳测点,并与对照组进行了响应对比.研究结果表明:最佳测点的响应比对照组至少高 8 倍,验证了该方法的有效性.

Abstract

This paper presents a method for selecting sensor measuring points of aeroengine under aerodynamic load.Based on the finite element model of the test rig of a single rotor system of similar design,the aerodynamic load characterization model was established.A response calculation method was proposed to calculate the sensitivity of the response to aerodynamic load according to the surface response of the casing.Based on the results of sensitivity analysis,the effective independence method was used to analyze the independence of measuring points on the casing surface.Combined with the sensitivity and independence,the optimal sensor location was selected,and the response of the control group was compared.The results show that the response of the optimal location is at least 8 times higher than that of the control group,which verifies the effectiveness of the method.
