摘要
针对火箭弹引信主动段时间较长,已有的实验设备无法模拟解保过程中加速度变化的问题,提出了MEMS保险机构加载模拟装置。该装置具有两个旋转机构,分别由电机和扭簧驱动。通过改变电机的转速和扭簧的力矩,可以在一定范围内调整加速度幅值和加载持续时间。实验结果表明,该装置具有结构简单,操作方便,适用范围广的特点,对MEMS安保机构可实现数千g加速度和数毫秒持续时间的加载模拟。
The specific acceleration change is hard to be simulated when a certain type of rocket projectile lunched. This paper proposed a loading device that could solve the mentioned problem. The device had two rota-ting mechanism, respectively driven by motor and torsional spring. By changing the speed of the motor torque and torsional spring, the acceleration amplitude and duration of loading could be adjusted in a certain range. The experimental results showed that the device had simple structure and the operation was convenient, which could simulate the loading of thousands g maintaining several ms of MEMS safe and arming system.
