本文提出了应用非线性规划方法设计铲运机工作机构。首先分析了反转六杆机构工作过程中的运动几何关系,推导了运动方程和力学关系方程。确立了以机构平动性能和转斗油缸最大出力为最小的双目标函数,从而建立了约束非线性优化设计数学模型。 作者用所建立的数学模型,用SUMT优化方法,在高速电子计算机上,对国产ZLD-40型铲运机工作机构进行了实例计算,验证了数学模型及程序的正确性和可靠性,并取得了满意的优化解。 计算结果表明:该机构选择双目标函数进行优化设计,较全面地提高了机构的设计质量和工作效益,这是常规设计所难以实现的。
In this paper, we propose to design the working mechanism of scraper using nonlinear programming method. First of all, the geometric relations of the movement of the six-bar mechanism are analyzed, and the equation of motion and the equation of mechanics are deduced. The dual-objective function with the translational mechanism of the mechanism and the maximum output of the cylinder is established. The mathematic model of constrained nonlinear optimization design is established. Using the mathematical model and SUMT optimization method, the author calculates the working mechanism of domestic ZLD-40 scraper on high-speed electronic computer, verifies the correctness and reliability of the mathematical model and program, and obtains Satisfied with the optimal solution. The result of calculation shows that this institution chooses two-objective function to optimize the design, which improves the design quality and work efficiency of the whole organization, which is hard to be achieved by conventional design.
