The invention relates to a maglev traffic linear synchronous motor suspension force model establishment method, which comprises the following steps: (1) dividing motor working states according to excitation current, air gap height and stator current working intervals of a linear synchronous motor; (2) establishing a finite element model of the linear synchronous motor, and performing time-step finite element simulation on each working state of the motor to obtain suspension force data of the motor in different working states and at different secondary positions; and (3) carrying out Fourier decomposition on the suspension force data, and carrying out nonlinear fitting to obtain a suspension force analysis model. Compared with the prior art, the suspension force analytical model established by the method is based on the Taylor series and the power function, the expression is simple, the method is easy to use, meanwhile, the model precision is high, and the method has very high application value.
