Optimization and Performance Improvement of Mechanical Structure Based on Finite Element Analysis
As an advanced computer simulation technology,finite element analysis(FEA)has become a common method for optimization and performance improvement of mechanical structure design.In this paper,we take the optimization of excavator bucket bar structure and the optimization of hydraulic press upper crossbeam structure as examples to discuss the optimization and performance improvement of mechanical structure based on finite element analysis.Firstly,the structure of excavator bucket bar is modeled,optimized design variables and constraints are selected,structural optimization calculations are carried out and the results are analyzed to obtain the improved structure of excavator bucket bar.Then the structure of the upper crossbeam of the hydraulic press is modeled and simulated,and the stress distribution and displacement of the upper crossbeam of the hydraulic press are obtained through simulation,and the optimization and improvement are carried out to obtain the improved structure of the upper crossbeam of the hydraulic press.
