  • Accordingtothestresswavetheory,thebufferandshockabsorptionstructureofadatarecorderwasdesignedbyconsideringthereasonableallocationofthegeneralizedimpedancerat o.The compositestructureforshockabsorptionwasdesignedtosolvetheproblemofnarrowspaceimpact protection.AndtheoptimizationwascarriedoutbycombiningIsightandLs-dynatoreducethedynamicstressoftheprotectedcomponentratherthantheimpactacceleration. Asaresult,thedynamic stressoftheprotectedcomponentdecreasesbyabout70.9%andthemassofthedatarecorderreduces 300gram.Intheend,thebombardmenttestwasperformedandthedatawererecoveredsuccessfully.
