机械加工系统节能降噪型综合任务分配模型及其应用

节能、降噪是机械加工系统实施绿色制造需要考虑的主要问题之一。曾分别对节能、降噪为单目标的任务分配问题进行了研究,但实际中既要考虑能耗问题,又要考虑噪声问题。鉴于此,将能耗问题和噪声问题综合考虑,建立了一种机械加工系统中节能降噪型多目标综合任务分配模型;对模型的求解方法进行探讨,提出了一种基于遗传算法的模型求解过程。最后,基于空载功率和空载噪声对模型进行简化,提出了一种模型应用方法,案例分析表明该应用方法具有较好的效果。

INTEGRATED TASK-ASSIGNING MODEL OF ENERGY SAVING AND NOISE REDUCTION IN THE MACHINING SYSTEMS AND ITS APPLICATION

From the viewpoint of green manufacturing, energy saving and noise reduction are two important problems that should be considered in machining systems. The task-assigning model of energy saving and the task-assigning model of noise reduction have been studied respectively. But in machining practice, the energy consumption and the noise are coinstan-taneous, and need to be considered together in the task-assigning model. A multi-objective task-assigning model is established so as to consider both energy saving and noise reduction in machining systems. A flexible arithmetic based on genetic algorithm (GA) is also presented to solve the model. Based on the traits of unloaded power and noise of the machine tools, a practical method is developed that simplifies the application of this integrated model. Finally, a case study is analyzed to show that the model and the arithmetic are practically applicable.
