直升机振动与噪声综合评估方法研究

为了能够对直升机振动与噪声进行综合性的研究,系统地建立了一种以飞行员、机上设备和环境为基础的综合评估模型,并对振动与噪声的主要影响进行分析,构建了一个三层的指标体系结构;在研究各种综合评估方法的基础上,选择层次分析法(Analytic Hierarchy Process)与模糊综合评估法(Fuzzy Comprehensive Evaluation)对构建的模型进行评估;同时应用MATLAB开发平台对提出的方法进行仿真;最后选择样例直升机进行案例分析,对提出的方法进行验证。仿真结果表明,该方法能够从定性与定量的角度综合描述直升机振动与噪声对飞行员、机上设备和环境的影响,为直升机振动与噪声的评估提供了一种新的途径,可以在直升机的研制、试验和使用等阶段进行应用和推广。

The Research on the Comprehensive Assessment Methods of Helicopter Vibration and Noise

In order to carry out a comprehensive research on the vibration and noise of the helicopter, this paper establishes a model of comprehensive assessment based on the pilot, machine equipment and environment, analysis and the main influence on the vibration and voice, and constructs a three layer of the index system structure; Assess the model constructed with the methods of analytic hierarchy process and fuzzy comprehensive evaluation based on the study on various comprehensive evaluation methods; At the same time, simulate with the MATLAB development platform; At last, we verify the proposed method by analyzing a helicopter which was chosen as the sample. The simulation results show that the method proposed could describe the effect of the helicopter vibration and voice on the pilot, equipment and environment from the view of qualitative and quantitative, which would provide a new way for the assessment of helicopter vibration and voice, and also could be applied and extended at the phases of the development, testing and use of helicopter.
