飞机振动响应采用计算手段确定存在较大的误差,为保证飞机机载产品可靠性试验的有效性,相关国、军标准推荐优先使用实测振动应力.为准确合理地确定可靠性振动应力,对某型号飞机进行了全机振动环境数据的实测、处理与归纳,提出了基于可靠性试验的环境数据处理方法.利用动压作回归参数,对实测数据进行归纳,得到了较高拟合优度的结果,有较强的工程适用性. In order to ensure the reliability of aircraft on-board product reliability test, relevant national and military standards recommend giving priority to the use of measured vibration stress. In order to accurately and reasonably determine the reliability of the vibration stress, Model aircraft is used to measure, process and summarize the data of the whole machine vibration environment, and put forward the method of environmental data processing based on the reliability test.Using the dynamic pressure as the regression parameter, the measured data are summarized and the higher fitting goodness As a result, there is a strong engineering applicability.
