摘 要:该文提出多级同步感应线圈发射器弹载存储动态测试技术。首先,基于电磁场理论定量分析了同步感应线圈发射器发射过程中存在的强脉冲和高过载环境;其次,设计具有抗电磁干扰且抗高过载能力的弹载存储测试装置,并分析了装置的屏蔽效能和承载能力;最后,研制带弹载存储测试装置的测试弹,并开展了30级同步感应线圈发射器动态发射试验,得到同步感应线圈发射器动态过程中磁感应强度数据和加速度数据,与仿真数据吻合,且误差可控制在4.7%,同时揭示了发射始末测试弹存在“规律碰撞”效应和“周期章动”现象。With the maturity of electromagnetic launch technology,research on electromagnetic weapon test technology is gradually carried out.Due to the influence of a strong pulsed magnetic field and high overload environment in the electromagnetic launch,current research focuses on the non-contact external measurement method,and the on-board storage test technology of electromagnetic weapons has not formed a comprehensive test data system.Therefore,this paper analyzes the launching environment of the synchronous induction coil launcher,then designs the missile-borne test system.After the dynamic launch test verification,the missile-borne storage test technology of the synchronous induction coil launcher is finally formed.Firstly,the simulation model of synchronous induction coil emitter is established by taking the multistage drive coil and the testing projectile as the research object.(1)The axial magnetic induction intensity of the test projectile increases first and then decreases with the launch time.The peak value at the tail area of the armature reaches 4.2 T,and the variation in radial magnetic induction intensity is consistent with that in the axial direction.However,the amplitude in the tail area is much smaller than in the axial direction.(2)The thrust of the test projectile fluctuates periodically with the launch time.The thrust of the initial test projectile,triggered by the first-stage driving coil,reaches its maximum axial value at 778.3 kN within 2.2 ms and then stabilizes,fluctuating around 750 kN.When the last stage driving coil is triggered,the axial thrust instantaneously becomes negative,reaching a peak amplitude of-457 kN.Secondly,a missile-borne storage test device is designed and placed at the test warhead.The miniaturized circuit module is equipped with a uniaxial magnetic field/acceleration sensor to realize the automatic triggering test of the axial acceleration and internal magnetic induction intensity.Choose the passive mode to realize the shielding design with special materials for the outer l
