摘要

摘要: 研究了配装某型飞机发动机的新型复合结构航空测量耙的组成结构，使用ANSYS软件对其进行了模拟分析。基于有限元分析结果，对新型航空测量耙振动应力测量方案进行了设计，并对方案的有效性进行了评估分析。分析结果表明：方案设计拟定的各振动应力测点的最大拉压应力较对应截面的最大拉压应力的误差不超过2.5%，低于工程可接受的误差要求，说明新型航空测量耙振动应力测量方案设计合理有效。

Abstract: Structural composition of a new-type composite-structure aero measuring rake which is equipped on aircraft engine is investigated and the computer simulation for it by using software ANSYS is carried out. Conception for vibration stress survey of the new-type aero measuring rake is designed, and the evaluation analysis for the conception is conducted based on finite element analysis results. Simulation results show that errors of maximum tensile stresses of vibration stress measuring points, which are chosen by project design, compared to corresponding sections are not exceeding 2.5%, which is lower than engineering acceptable error demands. The rationality and validity of conceptual design for vibration stress survey of a new-type aero measuring rake is verified and important reference is provided for design and modification of this rake.
