The double crystal monochromator (DCM) is a spectrometer in synchrotron radiation beamlines, and its stability directly impacts the quality of emitted light. In order to meet requirements fourth generation light sources, researchers have designed DCM using an active control method ensure by actively compensating for displacement through voice coil motors. imposes high demands on vibration isolation performance frame. response external excitation characteristics, this paper proposes quasi-zero stiffness (QZS) system based compressed buckling beam structure. Random simulations finite element analysis revealed that, under different operating conditions, 3σ core part maintained at nanometer level. Moreover, presents calculation elastic potential energy establish force equilibrium equations negative analyzes stress distribution during derived deflection curve. Validation confirms method’s accuracy calculating distribution. Because structural similarities, some results can be applied study honeycomb materials.
