以Mark 7Mod 1型阻拦系统为基础,借助其中的油液流量系数的经验公式,将其扩展到Mark 7Mod 3型阻拦系统。首先,将K-5型凸轮曲线进行扩展,重新设计凸轮曲线,使主液压缸的行程增加到4.65m,进而增加了阻拦系统的容量,实现阻拦系统的优化。其次,考虑到主液压缸的质量不能被忽略,通过引入绳索的弹性形变,实现了阻拦过程主液压缸惯性、滑轮缓冲装置的惯性和飞机惯性的综合动力学仿真。再次,增加了滑轮缓冲系统,使阻拦系统的液压模型更为准确、完整。最后,在考虑了凸轮阀控制曲线以及锥形阀流量系数等各项参数变化的情况下,研究飞机各状态与阻拦系统中各参数的相互影响情况。
Based on the Mark 7Mod type 1 barrier system, it is extended to the Mark 7Mod 3 blocking system with the empirical formula for its oil flow coefficient. First of all, the K-5 cam curve is extended to redesign the cam curve to increase the stroke of the master cylinder to 4.65 m, thereby increasing the capacity of the blocking system and optimizing the blocking system. Secondly, considering the mass of the master cylinder can not be neglected, a comprehensive dynamic simulation of the inertia of the master cylinder, the inertia of the pulley cushioning device and the inertia of the aircraft is realized through the elastic deformation of the introduced rope. Thirdly, the pulley buffering system is added to make the hydraulic model of the blocking system more accurate and complete. Finally, taking into account the control curve of the cam valve and the flow coefficient of the conical valve, the interaction between the various parameters of the aircraft and the parameters of the blocking system is studied.
