摘要
机床主轴的设计除了要考虑其强度和刚度外,尚须考虑其动态特性。机床主轴的动态特性设计可归结为特征值反问题的求解。本文研究了基于人工神经网络和遗传算法的机床主轴动态特性结构优化设计的求解方法,利用人工神经网络实现机床主轴动态特性的近似分析,借助遗传算法实现给定固有频率下的最小重量设计。计算结果表明了该方法的有效性。
In addition to the strength and rigidity, the dynamic properties of machine tool spindle should be considered. The dynamic properties of machine tool spindle can be classified as the solution to inverse eigenvalue problem. In the paper, the solution to the optimal structural design of machine tool spindle with respect to dynamic properties based on artificial neural network and genetic algorithm is studied. The digit solution shows that the method is effective.
