Acceleration has complicated changes in airdrop process, overload is the most important. Aiming at the phenomenon, an acceleration recorder of high overload resistance was designed. Furthermore, with combination of theoretical derivation with test, actual validation was given. Firstly, the Marshall's hammer impact test was used to examine overload resistance performance: Secondly, parachate-opening overload test was used to simulate rockets block and acceleration data was obtained. Finally, comparison was made between the test results and theoretical calculation, the error was found within 8%, this shows the recorder has practical value.
