Abstract:
On the basis of accurate mechanical calculation, the author takes X type of rocket launcher as the ex ample to analyze the influence of the changes of the major st ructure design parameters on rigidity, strength and mass of the bottom frame of the multiple-barrel rocket launcher and calculate the sensitivity of parameters. The conclusion is drawn that the longitudinal beam is the key component in influencing the mechanical characteristics. And by the method of fuzzy group decision of st ructure parameters, the optimized parameters are selected and the mechanical capabilit ies of the structure are improved. The maximum of displacement and stress are reduced considerably, in the mean time, guaranteeing the decreasing of the mass of the structure. The conducted research provides a practical guide for structure design and modification of the bottom frame.
