飞机环境振动状态-时间谱是飞机的一种重要的统计参数。它是运用状态归纳法进行环境振动数据归纳所必不可少的先知条件。本文提出了飞机环境振动状态-时间谱的一个编制方法。该法建立在大量飞行统计数据的基础上,并全面考虑了空中飞行和地面试车两种情况。由此编制出来的飞机环境振动状态-时间谱能较真实地反映飞机实际使用的情况。这个编制方法已用于工程实践中。
Aircraft environmental vibration state - time spectrum is an important statistical parameters of the aircraft. It is an indispensable prophet for inducing environmental vibration data using state induction. In this paper, a method for compiling the aircraft vibration state-time spectrum is proposed. The law is based on a large number of flight statistics and takes into account both the aerial flight and the ground test. The resulting aircraft environment vibration state - time spectrum can more accurately reflect the actual use of the aircraft. This method of preparation has been used in engineering practice.
