THE RESEARCH ON THE DESIGN OPTIMATING TWO GOALS OF THE ROLLERS OF END SPINNING MACHINES

By analysing the motion and the work of the spinning roller base,this paper establises two objective functions respectively about profiling tolerance and energy consumption,sets up binding conditions according to strength,stablity,specific pressure on guideway and connected dimentions.The optimization with two objectives is first used to design the spinning roller base of morden spinning machines,and the optimum method and the results are discussed.
