【摘要】：混合高阶傅里叶非圆齿轮驱动的差速泵,排量、脉动率和齿轮不根切最大模数等性能指标影响因素复杂,为了方便快捷地获得最佳参数,建立混合高阶非圆齿轮阶数与差速泵叶片参数的基本关系和混合高阶傅里叶非圆齿轮传动数学模型;建立了排量、脉动率和不根切最大模数的子目标函数,使用功效系数法建立差速泵性能的多目标评价函数,采用遗传算法求解多目标函数,得到相同泵腔尺寸下具有最大排量和最小脉动率的满足不根切最大模数大于1.5的混合高阶傅里叶非圆齿轮阶数比和节曲线参数非劣解,优化后的差速泵最小脉动率为22.04%,排量为3 870.44 m L,相比已有文献,脉动率降低11.3%,排量增加3%。
[Abstract]:The mixed high-order Fourier non-circular gear drive differential pump, displacement, pulsation rate and gear non-root cutting maximum modulus and other performance factors are complex, in order to obtain the best parameters conveniently and quickly, The basic relationship between the order of hybrid high-order non-circular gear and the blade parameters of differential pump and the mathematical model of hybrid high-order Fourier non-circular gear transmission are established, and the subobjective functions of displacement, pulsation rate and maximum modulus of non-root tangent are established. The multi-objective evaluation function of differential pump is established by using the efficiency coefficient method, and the genetic algorithm is used to solve the multi-objective function. The order ratio of mixed high-order Fourier non-circular gears and the non-inferior solution of nodal curve parameters with maximum displacement and minimum pulsation rate of the same pump cavity are obtained, which satisfy the maximum modulus of non-root tangent larger than 1.5, and the order ratio of the mixed high-order Fourier non-circular gear and the nodal curve parameter are obtained. The optimized differential pump has a minimum pulsation rate of 22.04 and a displacement of 3 870.44 mL. Compared with the previous literatures, the pulsation rate is reduced by 11.3m and the displacement is increased by 3 parts.
