In this paper, the Lorentz force detuning of superconducting cavity is illustrated and discussed in detail. The static lorentz force detuning and dynamic lorentz force detuning of a 704MHz/beta = 0.45 single-cell superconducting cavity is calculated with numerical simulation method. And the mechanical stability of the cavity is also studied. Finally a method for stiffening cavity is proposed.
