Research on Movement Characteristics of Launching Mechanism of Portable Missile Launcher

Abstract

According to the design requirements of portable missile launchers, the launch mechanism is utilized to provide a structure that can finely adjust the launching angle according to the movement of the target to be attacked. Using the procedure of theoretical calculation and simulation, this dissertation focuses on the key technologies in the design and application of the overall structure of the portable missile launcher, and uses the ADAMS software to simulate the launch mechanism. The launching mechanism model with the secondary clearance of movement is established. The mathematical model of the launcher with clearance is established by Lankarani-Nikravesh method and the movement process of the launching mechanism is simulated by ADAMS dynamic simulation software to test the movement accuracy when the launcher has different clearances. Through the simulation results, it can be seen that there are distinct influences on the movement of the mechanism when there is a movement gap in different positions of the launching mechanism. The simulation results are analysed, and the structure of the launching mechanism is modified according to the analysis results to obtain a better movement condition new launching agency.
