摘要
本文通过产品冲击试验分析易损零件的加速度响应,导出后峰锯齿脉冲谱公式。随后在三维空间内讨论易损零件的最大加速度与脉冲激励的关系,定义极限响应加速度和极限输入加速度,用截痕法寻出后峰锯齿脉冲的产品破损边界曲线的方程。
This paper, through product impact test to analyse the acceleration responseof vulnerable parts, deduces the impact spectrum equation of back peak zigzagpulse. Then, in three dimensions, it discusses thc relationship between the maxi-mum acceleration and pulse excitation, defines the limit response accelerationand tne limti input acceleraton. Finally, using cross section method, the equationof product crash boundary curve of back peak zigzag pulse is deduced.
