Abstract: Engineers need the special software for predicting fatigue life of unmanned aerial vehicle transported on camion under excitation of random road surfaces in order to reduce greatly the amount of testing otherwise needed.According to the theories of fatigue life prediction，the authors develop the corresponding fatigue life analysis software.Concretely，the traditional local stress-strain approach is adopted.For solving the nonlinear equation and system of nonlinear equations of the traditional local stress-strain approach，in term of the excitation difference among the A，B，C and D level road surface，the self-adaptive algorithm is presented.Finally，the authors use the self-adaptive algorithm to predict the fatigue life for an unmanned aerial vehicle transported on camion in a type of task section.

Key words: unmanned aerial vehicle transported on camion, self-adaptive algorithm, fatigue life prediction
