通过对矿山设备回转体零件圆度误差实际工况的深入分析,提出了基于虚拟仪器的设计思想,以图形化开发平台Labview为技术核心设计开发了基于Labview的矿山设备回转体零件圆度误差分析系统。针对圆度误差分析中最小区域法的特点,论文采用一种改进遗传算法对圆度误差进行了优化。该方法较传统遗传算法作了改进,采用实数编码,基于搜索点的适应值变化趋势进行定向变异并自适应地改变变异步长,可达到较高的精度值。

With the deep analysis on the actual performances of the roundness error for the rotary component of the mine equipment,base on the design conception of the virtual instrument,the figurized development platform Labview as the technical key was applied to design and develop the analysis system of the roundness error for the rotary component of the mine equipment base on the Labview.According to the features of the minimum area method in the roundness error analysis,an improved genetic algorithm was applied to optimize the roundness error.In comparison with the conventional genetic algorithm,the improved genetic algorithm was improved with the real number code.Base on the adaptive value variation tendency of the search point,the directional variation conducted and self suitably exchanged the varied step size to reach a high accuracy value.
