中文摘要：
选取一对外啮合渐开线斜齿圆柱齿轮,以其分度圆圆柱体积最小为优化目标函数,建立数学模型。为满足斜齿轮齿根弯曲强度和齿面接触疲劳强度,运用改进的遗传算法将求解过程简化,得到最优解。并利用ABAQUS有限元软件,对齿轮啮合进行有限元强度分析,最后将分析结果进行模拟显示。结果表明,利用遗传算法求解斜齿轮问题便捷可靠。
英文摘要：
In this paper,a mathematical model is established for optimization of the objective function of the external meshinginvolute helical cylindrical gear with the minimum size of the cylindrical helical cylindrical gear. In order to meet the helicalgear tooth root bending strength and tooth surface contact fatigue strength,the optimal solution can be obtained by using thegenetic algorithm to simplify the solving process. The ABAQUS finite element software is used to carry out finite element analy-sis of the gear mesh. Finally,the simulation results are shown in the end. The results show that using the genetic algorithm tosolve the problem of helical gears is simple and reliable.
