Topology Optimization of MM52160 Gantry Rail Grinder Column

Structural topology optimization of the MM52160 gantry rail grinder column is carried out. Three- dimensional model of the column is built for static analysis and model analysis. The original model is simplified without changing its quality. The results showed that： the maximum static displacement of the simplified model is reduced 2.421xm than the original model, the first order natural frequency is increased by 2.85%. Topology optimization of the simplified model, the material distribution is checked. Dynamic and static stiffness al~ used to analyze the optimized structure, analysis results show that the maximum static displacement of the optimized structure is reduced 0.811xm than the original model, the first order natural frequency is increased 3.72%, tile weight is decreased 15%. Through the structural topology optimization, its dynamic and static stiffness are improved, but the weight is decreased.
