提出了一种采用LabVIEW并行运算提高传统遗传算法计算速度的方法,可实现多核计算机多线程的同时运算,从而大幅度提高运算效率.Ni--Ti合金线材无模拉拔初始阶段拉拔速度路径优化结果表明,在八核计算机上采用基于LabVIEW的多线程并行运算程序,与基于文本编程的MATLAB运算程序相比,前者运算时间仅为后者的1/8左右.Ni--Ti合金线材无模拉拔实验结果表明,采用本文智能优化后的拉拔速度路径,可使线材直径波动长度缩短至24 mm,远小于线性或S线型路径的最小直径波动长度.
A parallel method based on LabVIEW is proposed to improve the computational speed of traditional genetic algorithm, which can realize the simultaneous operation of multi - threading in multi - core computer and thus greatly improve the computational efficiency.The drawing speed path in the initial stage of die - less drawing of Ni - Ti alloy wire The optimization results show that using the multi - thread parallel computing program based on LabVIEW in eight - core computer, compared with the MATLAB programming based on text programming, the former computing time is only about 1/8 of the latter.The Ni - Ti alloy wire has no The results of die drawing experiments show that the length of wire diameter fluctuation can be shortened to 24 mm, which is far less than the minimum diameter fluctuation length of linear or S-shaped path by adopting the intelligent and optimized drawing speed path.
