Design and simulation of elastic guiding mechanism for missile

This study designs a new type of elastic separation guiding mechanism made up of the elastic rod and the steel ball. The mechanism can be used into the long stroke separation of missile and take full advantage of the elastic rod´s damping effect to reduce the relative deflection and collision probability of the separation bodies. A mathematical model regarding the guiding mechanism and the separation process has been established in this paper to detect the influence of the stiffness coefficient and the preload force of the guiding mechanism having on the separation process. The simulation results demonstrate that both the stiffness coefficient and the preload force are very important for missile separation, and then we further obtain their optimal values in a certain stage separation process.
