[Abstract]:Under the background of the global climate change problem causing the attention at home and abroad and our country actively developing low carbon economy and implementing energy saving and emission reduction, the problem of high energy consumption and high emission exists in the manufacturing industry of our country. A new manufacturing mode-low-carbon manufacturing emerges as the times require, which promotes manufacturing enterprises to walk out of a sustainable development path. In view of the multi-source coupling, dynamic and complex characteristics of manufacturing system, the characteristics of carbon flowing state of manufacturing system are analyzed, and its essential characteristics are grasped, so as to maximize the utilization ratio of resources and energy and minimize the waste emissions produced by production process. This has important guiding significance for enterprises to implement low-carbon manufacturing. In this paper, supported by the National Natural Science Foundation of China and Chongqing Natural Science Foundation, the characteristics of carbon flow characteristics and modeling methods of mechanical manufacturing system are studied. First of all, starting from the characteristics of mechanical manufacturing system, the characteristics of energy flow and logistics are analyzed, and the boundary of carbon flow system of mechanical manufacturing system is established to analyze the characteristics of carbon flow state of the system, and based on the boundary of the system, The equation of material energy balance and the calculation model of carbon emission are derived, and the evaluation index of carbon efficiency is given, which lays the foundation of quantitative analysis for the establishment of the following dynamic model. Secondly, considering the continuity of energy consumption and the influence of discrete state on continuous process, combined with the basic principle of first-order hybrid Petri net, the carbon flow state model of mechanical manufacturing system is established, and the formal definition of the model is given respectively. The rules, conflict resolution strategy, dynamic characteristics and modeling module are analyzed. At the same time, control arcs and suppression arcs are introduced to enhance the modeling semantics of the model and simplify the model. Thirdly, the carbon flow state model of mechanical manufacturing system is analyzed and studied from the aspects of objective function, constraint condition and model optimization strategy. The simulation environment based on Matlab is adopted, and the linear time-varying discrete time state variable is used as the foundation. The optimization algorithm of carbon flow state model is presented. Finally, taking the gear shaft produced by a flexible automatic production line of Chongqing Machine tool Group as an example, the production line is modeled, the objective function and constraint conditions of the model are analyzed, and the simulation software is combined. In order to verify the feasibility of the proposed method, the characteristics of carbon flow state of the production line are quantitatively analyzed.
