摘　　要：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。In order to do a comprehensive study on vibration and noise of helicopters, a model of comprehensive assessment based on pilot, machine equipment and environment was built here to analyze the main influence factors on helicopter vibration and noise and constructs a three-layer index system structure was contructed. The model constructed was assessed with the analytic hierarchy process method and the fuzzy comprehensive evaluation method after studying various comprehensive evaluation methods. At the same time, the simulation for the new methods was done with MATLAB development platform. At last, some examples of helicopters were chosen to do case study with the proposed method. The simulation results showed that the method proposed can describe the effects of helicopter vibration and noise on pilot, equipment and environment qualitatively and quantitatively. The results provided a new way for the assessment of helicopter vibration and noise, this method could be applied and extended in development, testing and use of helicopters.
