Electric actuator for air-to-air missile is a complex structure with some nonlinear factors, such as clearance and friction.Its precise mechanics modeling technology for electric actuator is the key of missile’ s structural dynamics active design.Based on the electric actuator for a certain air-to-air mis-sile, digital model of the actuator is established using finite element software-ABAQUS.As friction, clear-ance and thread connection changing, the influence law on system static stiffness is studied.Through the-oretical analysis and experimental research on static stiffness, the method of modeling and analyzing for complex structure with strong nonlinear factors is obtained, which provides theoretical basis for active a-nalysis and design of missile structure dynamics.
