连发射击人枪系统机械导纳测量与分析

该文针对立姿无依托连发射击的情况建立了枪肩系统的抵肩力及枪肩运动的电测系统，利用电测数据求取了枪肩系统的机械导纳函数，采用正交分量法对枪肩系统的导纳函数进行了模态识别，并探讨了连发武器系统被动态与主动态的主要差异，即刚度、质量及阻尼有所不同，但曲线的变化规律及各峰出现的频率基本一致。

Measurement and Analysis of Automatic Firing Gun-man System Mechanical Admittance

This paper makes an electronic measuring system of shoulder' s receiving force and gun-shoulder movement of gun-shoulder system in view of characteristics of standing non-rest firing accuracy. The mechanical admittance function of gun-shoulder system is procured by using electronic measuring data. The models are identified for the admittance functions of gun-shoulder system by a-dopting an orthogonal component method. The main differences of the automatic weapon between passive state and initiative state are discussed. The results show that there are some differences between stiffness, quality and damp and that the diversification law of the curve and the frequency of each apex are identical.
