For coupling vibration problem of flexible guides activated by moving missile, based on the Hermite interpolation functions, an explicit generation algorithm of flexible curve was proposed. The coordinates of interpolation points were extracted with the help of CBKSUB subroutine development, so the flexible curve could be updated in real time. A dummy-based point-to-curve constraint modeling, Marker-in-curve modeling were constructed respectively for missile-guides coupling vibration. Results showed that the simulation results were in good agreement with the experimental data, and the algorithm stability and the computational efficiency were improved obviously. The method gave a new ideas for complex missile-launcher system coupling vibration modeling.
