摘　　要：悬索火箭橇水平运动控制精度受到悬索初始拉力、悬索材料特性、侧向风等因素的影响。为了分析这些因素对悬索火箭橇水平运动的影响,文中利用Newton法对悬索和橇体进行动力建模,仿真计算了三自由度火箭橇运动。利用本方法分析了国内某超音速悬索火箭橇试验系统的水平飞行控制精度,计算结果与试验测得火箭橇水平运动数据吻合,说明文中方法的有效性。Rocket on the rope is a new kind of rocket trace test instrument, rocket’s horizontal flight accuracy is affected by the following factors: static tension force, rope’s parameters, side wind’s disturbance and so on. For analyzing the influence of these factors, this paper uses the newton method to construct the rope’s and rocket’s dynamical model, and uses finite element simulation method to calculate the rocket and rope’s 3 dimensional movement. The analysis method raised in this paper applied to the design of a new kind of supersonic rope controlled rocket flight system. The calculation result is close to the rocket’s horizontal deviation characters detected in the early day’s test, it proves the new analysis method’s effectiveness.
