Abstract 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.
