Layout optimization of robot forging unit based on genetic algorithm

Abstract

To improve the productivity of automated forging production units, reasonable layout is very important. In this paper, the layout optimization method of the robot working unit was studied to improve the production efficiency of forged crankshaft products, the bottleneck production unit is taken as the research object to find a satisfactory solution to the layout planning. Based on a mathematical model, a hierarchical description method of robot workspace and a prediction method of transition points were proposed. The robot running time and operability were used as evaluation indexes of the layout. The NSGA-II algorithm was used to optimize the layout scheme to obtain a better solution, and the optimized solution has better operability and runtime performance. The simulation results of professional software showed that the proposed layout optimization method and layout scheme were reasonable and significantly improved.
