摘要
针对直线度误差评定方法中评定基线难以确定的现状,提出和声搜索评定深孔轴线直线度误差的方法;以形状位置公差评定的最小条件原则为基础,以任意方向直线度误差评定的最小包容区域法为检测模型,将和声搜索算法与评定基线寻优相结合;分析了和声搜索算法的操作原理,将和声记忆库中每行的信息对应一条评定基线,通过和声记忆库的更新搜索最优评定基线;经检验和声搜索评定方法可行,根据MATLAB计算结果分析和声搜索算法能够提高直线度误差评定精度,可以为任意方向直线度误差的评定提供参考。
During evaluating straightness error it is difficult to determine the evaluation baseline,for the status quo proposed harmony search method assessment deep hole axis straightness errors; based on minimum zone condition to shape position tolerance assessment principles,in any direction straightness error evaluation least envelope zone method as a model,combined harmony search with the evaluation baseline optimization;analysised of the harmony search algorithm theory,the information of each rowin harmony memory corresponding to a baseline assessment,by updating the harmony memory search for optimal evaluation baseline;upon examination harmony search assessment method is feasible,based on M ATLAB calculation results that harmony search algorithm could improve the accuracy of straightness error evaluation,it could provide a reference for the evaluation of straightness errors in any direction.
