摘　　要：针对飞机拦阻的重要性,分析了飞机拦阻动力学性能。采用基于吸收飞机动能的方法,考虑飞机发动机推力,建立了飞机着陆拦阻动力学模型。在分析拦阻力与拦阻索拉力关系和飞机拦停条件的基础上,给出了用飞机拦阻位移描述的飞机初始拦阻力和对中拦阻力的表达形式,并分析了偏心拦阻力的计算方法。算例表明:在拦阻系统拦阻能力范围及规定的拦阻距离内,飞机能够被拦停且满足飞机对最大过载的要求,该模型能解决原有模型中初始拦阻索拉力的突变和尖峰的问题。Since importance of research on aircraft arrestment, arresting system dynamics performance was studied. A dynamics model of arresting system was built based on absorbing aircraft kinetic energy, considering the aircraft thrust. The relationship between aircraft arresting force and arresting cable force was analyzed;also the aircraft stop conditions were given. Initial aircraft arresting force was expressed by polynomial with aircraft displacement, and the mathematic functions of symmetrical arresting force were built via the parameter analysis in this theoretical model. The aircraft asymmetrical arresting force regularities were shown, and asymmetrical arresting force was derived. The results indicate that the aircraft can be arrested in a certain distance,and the models satisfy with aircraft overload and the arresting system capability; the abrupt change and peak of initial arresting cable force are solved in stimulations.
