摘　　要：为防止某惯性测量单元电子线路板环境应力筛选振动试验发生“过筛选”的问题,本文提出一种基于优化设计电路安装支架结合传感器多点平均控制的试验方法,该方法能够有效降低电子线路板响应量级,可为防止电子线路板环境应力筛选振动试验“过筛选”提供参考和思路。In order to prevent the problem of "over screening" in the environmental stress screening vibration test of the electronic circuit board, a test method was proposed based on optimizing the design of circuit mounting brackets and combining sensor multipoint average control. This method could reduce the response level of electronic circuit boards. It could provide reference and ideas for preventing "over screening" in the environmental stress screening vibration test of electronic circuit boards.
