The invention discloses a DET and RELAP5 coupled dynamic characteristic analysis method based on a universal auxiliary variable method, which comprises the following steps of: constructing a DET simulation model of a discrete dynamic event tree, and modifying an input file TRIP card in a manner of increasing universal auxiliary TRIP variables according to a DET simulation object state transition type; the universal auxiliary TRIP variable is a variable type or a logic type; the simulation time step length is controlled by setting the simulation time of the RELAP5 program, and an output result file of each simulation step length of the RELAP5 program is analyzed; According to the DET simulation object state transition type, backtracking and executing the RELAP5 program. The method has the advantages that the setting process and method of the DET state transition object TRIP in the RELAP5 program input file needed by DET and RELAP5 program coupling are simplified, the modeling complexity is reduced, and the mod
