Abstract：
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/β=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.
