气动冲击试验系统输入特征对冲击谱形的影响
Effects of input parameters in a pneumatic shock test system on shock response spectrum characteristics
摘要
Abstract
The pneumatic vertical shock test system,due to its open-loop control,complex structure,and stringent test tolerance requirements,makes shock response spectrum(SRS)tuning particularly challenging.To address this,three key input parameters-gas source pressure,felt thickness,and impactor mass-were experimentally investigated using a controlled-variable approach on different transfer fixtures to determine their effects on the SRS.The results reveal significant coupling effects between these parameters.Notably,despite structural variations,each parameter consistently effects the SRS.These findings,corroborated by structural dynamic analysis,provide practical guidelines for SRS calibration.关键词
