摘  要：進行彈丸侵徹試驗時，試驗準備周期長。由于彈丸內部空間非常寶貴，測試儀必須做到微體積，其電池電量較??；測試儀需要提前上電。針對彈丸侵徹試驗準備時間長與測試儀電池電量有限的矛盾，以往采用引出導線，在試驗前斷線上電的方式。斷線上電需要彈體開槽，而且無意中磨斷導線導致提前上電，為此提出基于微沖擊開關的侵徹過載測試儀。測試儀沖擊開關安裝測試儀內部，不需要引出導線，在堂內加速階段通過沖擊開關進行實時上電，解決測試儀電池容量的問題。對沖擊開關進行沖擊驗證和空氣炮實驗，其可靠性得到驗證。實測數據分析，該測試儀能夠很好地完成彈丸侵徹過程數據測試。

關鍵詞：侵徹；上電；電池容量；沖擊開關

Abstract: It takes time to prepare for projectile penetration tests. Because the inner space of the projectile is very small， the tester must be designed with micro volume and low battery capacity. As a result， the tester needs to be powered on in advance. To overcome the contradiction between long preparation time and limited battery power， the most common way is to switch on by disconnecting the lead wire before test. This requires the projectile be slotted beforehand， but it is possible to rub off the wire by accident. So， a penetration overload tester with a micro-impact switch has been developed. The micro-impact switch， instead of the lead wire， is installed inside the tester and powered on in real time， which has solved the problem that the battery capacity is too small at the acceleration phrase of projectile bores. According to the impact test and air cannon impact test， the novel tester is reliable and can be used to complete the data test during penetration process.
