Abstract：In this paper, the horizontal slip table in 600 kN electrodynamic vibration equipment was studied. Numerical analysis and structure optimization were carried out to improve its axial resonance frequency, so as to further broaden the frequency range in vibration test. To analyze the slip table more accurately, the structure was divided into parts, and each of them was modelled in detail. At the contact surface, a novel bolt model was raised to simulate the connection between parts, which is easier to apply in finite element analysis. Through sensitivity analysis of several main structural parameters, the key parameters of the slip table to axial resonance frequency were extracted. Finally, these key parameters were optimized to increase axial resonance frequency. The results show that the optimized axial resonance frequency is increased by 8.72%, while the mass is reduced by 0.97%, the available thrust can be considered basically unchanged.
