Switchyard is an important part of the beam propagation system, the stability of which has a direct effect on the beam’s propagation. A model of the switchyard mirror mount is built by the finite element analysis software, a digital seismograph is adopted to measure the micro vibration of the mirror mounts' install base, the processed velocity power spectra are used as the loads and the beam direction of each optical elements is studied. The rotations of four optical elements of the switchyard are 0.338 mrad, 0.327 mrad, 0.289 mrad and 0.241 mrad, all less than the required stability index of 0.460 mrad. The error between analysis result and measurement one is 0.6%, which indicates that the analysis result is reasonable.
