Abstract: The ingot withdrawing device is one of the core components for the vacuum electron beam melting furnace, and its motion mode and speed have a significant effect on the stability of the withdrawing process and the structure of the ingot. Certain vibration can improve the surface quality and grain refinement of the ingot. Under the impact of vibration, the structure will generate additional deformation, and the strength of the related components also needs to be checked. In the pre-development stage, by combining the theoretical analysis of the simplified model and the simulation analysis of the real physical model, the vibration characteristics of the three-dimensional model for the vibrating ingot mechanism connecting table is studied. The vibration displacement amplification of the displacement sensor is analyzed, the optimization scheme is proposed to reduce the measurement error, and the strength of the structure is tested according to different working conditions. This work may provide some references for subsequent related structural design.

Key words: vacuum melting furnace, ingot withdrawing, vibration, simulation analysis
