In the process of arresting the landing of a carrier-based aircraft， the load and the acceleration are large， but the distance and the time are short，and they are affected by the conditions of aircraft carrier movement and airflow disturbance． There is a complex strong nonlinear multidisciplinary dynamics coupling problem． This paper establishes the UAV aircraft arresting hooksimple coupled multi-body dynamics model of a certain type of aircraft according to the experimental data obtained from the quality of the car to put forward a method of applying arresting loads by taking into consideration the effect of aerodynamic load，and by using the dynamic simulation software ADAMS for carrier-based aircraft landing on the basis of the rigid flexible coupling multi-body dynamics simulation analysis． In the process of arresting，the UAV aircraft posture changed quickly into a bow movement，and then maintained a relatively stable，body vertical acceleration along the fuselage from rear to front which first decreased sharply and then increased slowly． The distribution law of the stress and strain on the fuselage was that the landing gear and the arresting hook position were larger than that of others． The simulation results showed that the method can effectively simulate the landing process of a carrier-based aircraft with strong nonlinear complex loads，which can provide a reference for the whole process of carrier-based aircraft arresting， landing and the design of fuselage structure．
