摘要
为研究舰载机阻拦过程受力规律,提出了一种动力学与有限元相结合的阻拦过程仿真建模方法,采用动力学方法建立飞机机体六自由运动模型、尾钩运动模型及阻拦液缸运动模型,并采用有限元方法建立阻拦索波动模型、阻拦索与滑轮组及尾钩的作用力模型,仿真模型真实地反映了阻拦过程各项规律及影响因素,包括阻拦过程索的弯折波动、应力传递、尾构挂索后摆动及钩索滑移等过程,以及飞机偏心、偏航阻拦的影响规律,仿真结果验证了模型的有效性和优越性。
An approach integrating kinetics and the finite element method is researched on the arresting simulation model. The six degrees of freedom aircraft model,hook kinetic model and the cable hydraulic system model are cre-ated using the kinetics method,and the finite element method is used to develop the cable fluctuant model,the transferring of the tension on the cables,sheaves and hooks model. Some laws and influencing factors are reflected accurately with the arresting process in the simulation model. For instance the cable fluctuation,the tension trans-fer,the swing and slipping process of the hook after engaging with the cable,and the off center and yaw effects of the aircraft. The simulation results demonstrate the validity and advantages of this model.
