舰艇在不规则海浪中的摇荡运动,可由若干个振幅、周期和初始相位各异的单元简谐运动来表示,舰载导弹必须要受舰艇运动影响。本报告把舰艇、发射装置、导弹视为一个整体来考虑。除了舰艇的振荡运动外,还考虑了舰速、风速、环境温度、推力偏心、导弹质心偏移、发射筒的微变形、发射导轨的微弯曲、发射架初始瞄谁误差和气动力等因素的影响,建立了舰载发射扰动运动数学模型。此模型可结合不同型号特点,经分析简化后使用。
The warship’s oscillating motion in irregular waves can be expressed by a number of simple harmonic motion of units with different amplitudes, periods and initial phases. Ship-borne missiles have to be affected by naval movement. This report considers ships, launching devices and missiles as a whole. In addition to the oscillatory motion of the ship, factors such as ship speed, wind speed, ambient temperature, thrust eccentricity, missile center of mass deviation, microdeformation of the launch tube, microbending of the launch rail, initial error of the launching frame and aerodynamic forces are also taken into account , Established a mathematical model of shipborne launch disturbance motion. This model can be combined with different types of features, simplified analysis and use.
