安全保险装置是在引信安全系统中起隔爆和解保作用的装置,是安全系统的核心部件.本文设计了一种带有保险锁的MEMS安保机构,该安保装置利用后坐力及离心力解除保险,实验证明在后坐力大于26000 gn,离心转速大于18000 rad/min时装置可正常实现解除安保功能.
The Safety and Arming Device is the core component of the safety system which acts as the explosion and deinsurance function in the fuze safety system. The MEMS Safety and Arming device with an insurance lock was de-signed.The device used the recoil force and centrifugal force to relieve the insurance. Results show that when the re-coil force greater than 26000 gn ,centrifugal rotational speed greater than 18000 rpm the device can successfully real-ize safe and arming functions.
