Origins of vibration driving for airborne tactical missile during its term of being used were summed up and influences of load response for missile lug through different driving methods were studied to confirm the program for its vibration test. Theoretical calculation and FEM were used to compare influences of load response for missile lug through different driving methods. Origins of vibration driving for air missile were summarized and ascertained. The load res-ponses of missile lug under different excitation modes were calculated by theoretical calculation and finite element mod-eling and the driving method for vibration test was also confirmed in the end.
