Abstract

In order to investigate the launch response characteristics of vehicle-mounted missile weapon system under following-up and time-varying wind load, a finite element simulation model of vehicle-mounted missile weapon system was established in ABAQUS based on dynamics principle and finite element method, and the ABAQUS user subroutine was innovatively used for joint secondary development to realize the real-time loading of the following-up wind load. The influence of wind force on missile attitude and the vibration of launcher are analyzed under different wind speed, eccentric thrust angle and ground angle. The results show that the wind load not only has a great influence on the attitude of the missile out of the barrel and the vibration of the launch barrel, but also promotes or hinders the launch accuracy deviation caused by the eccentric thrust Angle and the inclination of the ground.

Key words： following-up; time-varying; wind load; vehicle mounted missile launch system; ABAQUS user subroutine
