Abstract:
To predict the delay arming time of a small caliber fuze magneto-rheological fluid safe and arming device,a delay arming time model is built by analyzing its energy loss of work.An empirical local resistance coefficient is revised by numerical simulation and its new value range is confirmed.The calculated delay arming time of the small caliber fuze magneto-rheological fluid safe and arming device is compared with the test data.The minimum error is 23.32% while using the empirical local resistance coefficient of an empirical formula,and the maximum error is 13.47% while using the empirical local resistance coefficient of numerical simulation,the error decreases by 9.85%.The calculation accuracy of the delay arming time of the small caliber fuze magneto-rheological fluid safe and arming device is affected by the empirical local resistance coefficient,and the empirical local resistance coefficient should be revised.
