摘要
已有的数据归纳方法中,极值包络法没有体现数据样本量和数据分布特性,文中依据人为给定置信度的统计容差法和改进的统计容差法给数据归纳的结果带来一定的偏差。文中依据正态分布下"累积频率函数"计算公式,结合参数的无偏估计理论,推导出给定概率下基于统计的与置信度无关的随机实测上限归纳方法,同时运用这一方法对国内某运输机机载雷达安装平台测量的数据进行处理,得到振动环境下实测归纳曲线。
Among the used data induction method, the number and distribution of the data was not embodied in the traditional envelop limits method, some error in the result was drive in the use of statistic tolerance method and the amended method depended on the given confidence coefficient. In this paper, Based on the equation of cumulative of frequency function under the normal school, combining with the theory of unbiased evaluation, a new method being in dependent of the confidence of coefficient was derived for induction of random environment measure data under the given probability value. Consequently, the method was used for dealing with data coming from one of airborne radar, and an induction curve was concluded from the natural measure data of vibration environment.
