The invention discloses a reliability analysis method for a ball-head biconical reentry vehicle. The method comprises the following steps: constructing a maximum temperature prediction model for the boundary of an internal cavity of the ball-head biconical reentry vehicle according to a deep neural network and a generalized chaotic polynomial; obtaining a labeled training data set and a non-labeled training data set; constructing a loss function based on the property of the generalized chaotic polynomial; based on the loss function, training a maximum temperature prediction model of the boundary of the internal cavity of the ball-head biconical reentry vehicle by using the labeled training data set and the unlabeled training data set; and performing prediction analysis on the maximum temperature of the boundary of the internal cavity of the ball-head biconical reentry vehicle by using the trained prediction model for the maximum temperature of the boundary of the internal cavity of the ball-head biconical reentry vehicle. According to the method, the maximum temperature of the boundary of the inner cavity of the ball-head biconical reentry vehicle can be accurately predicted under the condition that the geometric parameters and the material parameters of the ball-head biconical reentry vehicle are given, the calculation cost is reduced, and the analysis efficiency is improved.
