航天继电器多余物颗粒碰撞噪声检测的单周期稳定性分析

One-period Stability Analysis of Particle Impact Noise Detection for Space Relay Reminders

航天继电器的可靠性影响着国防电子系统的可靠性,而多余物问题的预防与检测是提高航天继电器可靠性的关键因素。颗粒碰撞噪声检测(PIND)是航天继电器多余物检测的行业规范,目前缺乏对其工作机理的理论研究,其检测效果并不理想。本文从动力学的角度,建立了PIND的数学模型,推导了粒子作单周期等幅振动的必要条件和稳定性条件,并给出了相应的仿真分析。

The space relay reliability influences the national defence system reliability seriously, and precaution and detection of relay remainder are the pivotal factors to enhance the relay reliability. Particle impact noise detection （PIND） is the industry standard, but there is a lack of working mechanism research. From the point of view of dynamics the collision mathematic models of relay remainder based on PIND are established, the necessary conditions and stability conditions when the remainder performing one-period equiamplitude motion are studied, and lastly the corresponding simulations.
