Study on High Anti-Vibration Machine Bed

Abstract:

Vibration is one of the most important factors affecting the accuracy and precision of machine bed. Under the definite structure, different materials and fillings will affect the natural frequency of the machine bed. 3 kinds of candidate materials (HT300.20#.20# & concrete) are selected to build different machine bed. Based on FEM, modal analyses are performed on the different machine beds, 4 sets of natural frequency are sampled on each one. Aiming to better performance in vibration, the machine bed is optimized with higher natural frequency. Through experimental study on the machine bed, it is clear that the optimized machine bed can meet the needs to perform better in machining.
