高速飞行器振动噪声环境预示技术

摘要

Technology of noise and vibration environment prediction of spacecrafts is critical for spacecraft system design and structure design. In this paper, status and development of the technology of noise and vibration environment prediction were reviewed. Due to author’s research experience, some main research concentrations were presented in the aspects of noise and vibration sources analysis, transmission property analysis, structural dynamic response analysis etc. Finally, it was pointed out that the research results in these concentrations may be helpful for solving the problem of the noise and vibration environment prediction in full-frequency bands and whole flying trajectory.%振动噪声环境预示技术是高速飞行器总体设计、结构设计的重要内容，对高速飞行器振动噪声预示问题的国内外研究进展进行简单回顾，再结合作者的工程与研究实践，从振动噪声源、传递特性和响应分析技术等几个方面，提出若干需要深入研究的关键技术，并指出这些技术的完善，将有助于高速飞行器全弹道、全频段振动噪声响应预示和控制问题的解决。
