摘要
针对加工时间可控的制造过程进行了能耗特性分析,基于加工任务的比能耗模型和机床待机功率建立了制造过程能耗模型,结合能耗实时监测系统提出了制造过程节能优化方法框架,即在既定调度方案的基础上,通过调整工序时间分布来实现对最大完成时间和能耗的进一步优化。分别定量分析了压缩和延长工序时间对制造过程能耗带来的影响,提出了压缩工时和延长工时的节能策略,具体研究了策略的适用条件和应用方法。通过案例分析,验证了该节能策略的有效性,为机械加工的节能优化提供了新的思路。
Based on the SEC(specific energy cost)model and standby power of machine tools,the energy characteristic analysis and energy consumption modeling of the manufacturing process with controllable processing times were carried out. Combined with real-time monitoring system,a framework of online energy-saving method was proposed, namely on the basis of the established scheduling scheme,implemented by adjusting the processing-time distribution to further minimize the makespan and energy consumption.The effects of compressing or prolonging process time on energy consumption in manufacturing process were analyzed quantitatively. Corresponding energy-saving strategies were put forward, and the applicable conditions and application methods of the strategies were studied in detail. The effectiveness of the online energy-saving strategy is verified through case analysis,which provides a new idea for the energy-saving optimization of manufacturing process.
