摘　　要：提出一种基于冗余电机驱动触发解锁的新型分离装置,利用一对夹口带有螺纹的释放夹咬合连接螺栓,实现连接功能。该装置具有快速释放分离、释放冲击小、可重复测试和使用等优点。经过方案设计、仿真分析和结构优化,对加工装配的样机进行了性能测试,结果表明:样机可承载10 kN,释放分离时间约56 ms,释放冲击为29.7g。A novel separation device actuated and unlocked by redundant motors is presented. Its fastening principle is that a couple of jaws with screw thread fix connecting bolt. The device has many advantages, such as quick separation, low shock, repeatable test and reuse. Through design, simulation analysis and structure optimization, a sample is fabricated and assembled. Then, performance test shows a preload of 10 kN, a release and separation time of 56 ms, and the release shock of 29.7 g.
