摘　　要：为获取曲柄滑块机构的最优传动性能,提出一种基于遗传算法的曲柄滑块机构尺寸参数优化方法。首先,构建基于改进遗传算法的优化模型,建立目标函数;然后对遗传算法进行改进,提高优化模型的性能;随后,通过对比基于不同算法的优化模型的有效性与稳定性,确定提出的基于改进遗传算法的优化模型适用于曲柄滑块机构尺寸参数优化,且具有稳定性;最后,利用基于改进遗传算法的优化模型对曲柄滑块机构的尺寸参数进行优化,并将优化前后的尺寸参数进行对比,优化结果为最小传动角的最优参数为a=43 mm,b=158 mm,e=38 mm,K=1.1,H=90 mm,此时最小传动角为58.8°,曲柄滑块机构的传动性能最佳。In In order to obtain the optimal transmission performance of the crank slider mechanism,this paper proposes a method for optimizing the size parameters of the crank slider mechanism based on genetic algorithm.Firstly,an optimization model based on improved genetic algorithm is constructed,and the objective function is established.Then the genetic algorithm is improved to improve the performance of the optimization model.Then,by comparing the effectiveness and stability of the optimization models based on different algorithms,it is determined that the optimization model based on the improved genetic algorithm proposed in this paper is suitable for the optimization of crank slider mechanism size parameters and has stability.Finally,the optimization model based on the improved genetic algorithm is used to optimize the size parameters of the crank slider mechanism,and the size parameters before and after optimization are compared,and the optimization result is that the optimal parameters of the minimum transmission angle are a=43 mm,b=158 mm,e=38 mm,K=1.1,H=90 mm,at this time,the minimum transmission angle is 58.8°,and the transmission performance of the crank slider mechanism is the best.
