摘　　要：针对热电池激活机构在低过载发射环境下内部摩擦力对激发器工作可靠性影响的问题,开展了一种低过载激活机构研究。将摆动锁止件引用到该机构中,作为该激活机构依靠弹丸发射时产生的惯性力使摆环转动释放击针的第二道保险依据。使用ADAMS动力学软件对热电池激活机构中摆环所受摩擦力对运动状况的影响进行分析,再通过离心试验对热电池激活机构进行测试。试验结果表明:该热电池激活机构在过载为50g、脉宽为0.8s内可靠解保,可确保被保险件的安全性,实现了引信机构小型化与快速激活能力,该激活机构适用于热电池内部激活引信。In order to solve the problem of the influence of internal friction on the operating reliability of the hot battery activation mechanism under low overload emission environment,a low overload activation mechanism was studied in this paper.The oscillating lock is introduced into the mechanism as the second safety basis for the activation mechanism to rotate the swing ring and release the pin by the inertial force generated when the projectile is launched.The ADAMS dynamics software is used to analyze the influence of the friction force of the swing ring in the hot battery activation mechanism on the motion condition,and then the hot battery activation mechanism is tested by centrifugal test.The experimental results show that the hot battery activation mechanism can be reliably released within 50g overload pulse width 0.8 s.Can ensure the safety of insured parts.The miniaturization and rapid activation capability of the fuze mechanism are realized,and the activation mechanism can be used to activate the fuze inside the thermal battery.
