【Abstract】 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.更多还原
