摘要: 为解决螺旋输送机在混凝土小预制件生产过程中的能耗高,效率低等问题,提出了一种面向高效率、低能耗的混凝土螺旋输送机设计参数优化方法。首先,建立混凝土螺旋输送机工作过程的速度和力学模型,揭示影响螺旋输送过程能耗和效率的重要因素。在此基础上,以螺距、转速和输送长度为优化变量,以螺旋输送过程总能耗最小、输送效率最大化为目标,建立混凝土螺旋输送机设计参数多目标优化模型,并提出一种基于改进的非支配排序遗传算法(NSGA-Ⅱ)进行优化求解。最后,通过将多目标优化结果与单目标优化结果进行对比分析,验证了所提出优化方法在提高混凝土螺旋输送效率的同时可有效降低生产能耗。

Abstract: To solve the problems of high energy consumption and low efficiency of the screw conveyor in the production process of small concrete precast parts,a high-efficiency and low-energy concrete screw conveyor design parameter optimization method was proposed.The speed and mechanical model of the concrete screw conveyor during the working process was established,which revealed many factors that affect the energy consumption and efficiency of the conveying process.Basically,to minimize the total energy consumption and maximize the conveying efficiency in the screw conveying process,a concrete screw conveyor multi-objective optimization model for design parameters was established.The screw pitch,speed and conveying length were used as optimization variables in the optimization model.Then,an optimization solution method based on fast elitist Non-dominated Sorting Genetic Algorithm (NSGA-Ⅱ) algorithm was proposed.By comparing the results of multi-objective optimization with that of single-objective optimization,the result showed that the proposed optimization method could effectively reduce energy consumption while improving transportation efficiency.

Key words: high efficiency and energy saving, concrete screw conveyor, multi-objective optimization, fast elitist non-dominated sorting genetic algorithm
