【Abstract】 Because the roundness error evaluation method has a complex structure and low accuracy,a new method of using backtracking search optimization algorithm( BSA) to deal w ith the roundness error is proposed by this paper. Firstly,the roundness error evaluation method and its mathematical model are briefly introduced; then the objective function of the roundness error is determined. Secondly,the basic principle of BSA is analyzed in detail,on this basis,the method and the concrete steps of the roundness error based on BSA are given. Finally,in order to verify the accuracy of BSA,the simulation experiments are carried out by this paper. The results of simulation experiments have show n that backtracking search optimization algorithm can evaluate the roundness error correctly and quickly.更多还原
