摘要
采用"黄金分割"规律,提出了压杆稳定设计的优化法。这种方法是将稳定因数φ=0.382作为第一次的试算点;通过对两种约束,压力一定,材料为Q235钢的压杆力学模型,利用优化法进行大量稳定设计截面的计算,并对计算结果分析统计及与试算法的比较表明,这种优化法能较快找到最佳值。
Put forward the optimization method of the struts stable design,using'golden section' rule.This approach will stabilize the factor φ=0.382 as the first spreadsheet point.By two constrains,when the pressure is determined,the material Q235 steel struts mechanical model use the optimized method for the calculation of a large number of stable cross-section design,and analyze statistical results and compare that.This optimization method can quickly find the best value,better practicality.
