The invention discloses a new multi-channel equilibrium correlation method of considering load distribution and damage consistency. The method comprises the following steps: (1) adopting rain-flow counting and zero-mean conversion methods to convert a load time process of each channel of a test field and a user into a sub-interval load spectrum; 2) converting the sub-interval load spectrum of eachchannel into fatigue damage according to a fatigue life prediction theory, and building a multi-channel sub-interval equivalent-damage correlation model; and 3) adopting a normalization method to normalize the damage of each channel sub-interval of the test field and the damage of the user corresponding channel. According to the method, load distribution consistency and damage consistency principles are comprehensively considered, consistent distribution of test field and user loads can be guaranteed, the consistent fatigue damage between a test field test and a user test can also be guaranteed, at the same time, adopting the normalization method solves the problem of poor matching equilibrium due to differences of signal types and orders of magnitude of all the channel, and a method of assigning different weights to all the channels is adopted to realize priority matching of the important channel.
