电池抗高g值冲击性能的研究

Study on the anti-high g shock capability of battery

针对在高g值冲击下,弹载存储测试装置的电池模块发生爆炸而导致测试失败的情况,选取测试装置常用的几种电池,利用Hopkinson杆对其在不同方向(沿平行和垂直的冲击方向)和石蜡灌封的状态下进行了抗高g值冲击性能试验。研究结果表明,经过冗余设计的电池有很高的抗冲击性。在约30万g的加速度冲击下,所试验的电池均没有发生爆炸。在目前弹体侵彻各种目标的加速度幅值范围内,所采用电池的可靠性可以保证。

In view of the test failure caused by the explosion of the battery module of the bomb-borne storage test device under high g-value impact,several batteries commonly used in the test device were selected and their anti-high g-value impact performance was tested under different directions(parallel and vertical impact directions)and paraffin filling by Hopkinson rod.The results show that the battery with redundancy design has high impact resistance.Under the acceleration impact of about 300,000 g,the tested batteries did not explode.At present,the reliability of the battery can be guaranteed within the range of the acceleration amplitude of the projectile body penetrating various targets.
