The invention provides a semi-analytic mutual inductance calculation method for a dynamic wireless power transmission magnetic coupling mechanism. In the design and optimization process of the magnetic coupling mechanism, the mutual inductance calculation method only needs one-time finite element simulation in the whole process, and the mutual inductance of the magnetic coupling mechanism under different receiving end positions and different receiving end structure parameters can be rapidly calculated; the problems that in the dynamic wireless power transmission magnetic coupling mechanism mutual inductance calculation process, calculation time is too long, the simulation workload is large, computer memory occupation is too large, and the physical concept is not clear in a traditional simulation calculation method can be solved, and the mutual inductance calculation speed and the design speed of the magnetic coupling mechanism are greatly increased. Meanwhile, according to the method, the analytic function re
