Machine tool manufacturing system energy efficiency analysis method

Abstract

The invention discloses a machine tool product manufacturing system energy efficiency analysis method. The method includes the following steps that: (1) energy consumption data are acquired based on a workshop energy consumption sensing network; (2) based on the acquired energy consumption data in a manufacturing workshop, a star type model is adopted to construct a manufacturing workshop energy efficiency data warehouse; (3) a machine tool manufacturing energy efficiency evaluation index system is the established, and energy utilization situations of product production and energy management are described; (4) energy consumption integrated models are established for a step layer, a process layer, a part layer and a product layer; and (5) simulation analysis is carried out based on the established energy consumption integrated models, and the specific values of the energy efficiency evaluation indexes of each layer are obtained. According to the machine tool product manufacturing system energy efficiency analysis method of the present invention, three-level energy efficiency management evaluation indexes are established based on the energy consumption data in the manufacturing workshop acquired by the sensing network; energy consumption integrated modeling is performed for energy utilization efficiency of each level; the energy utilization ratio of the workshop is calculated based on the energy consumption integrated models; and the energy utilization situations of the whole workshop and specific production equipment can be sensed.

Description

Technical field [0001] The invention relates to the research field of energy efficiency optimization control technology for manufacturing systems in the machine tool product manufacturing industry, and specifically relates to an energy efficiency analysis method for a machine tool product manufacturing system. Background technique [0002] As a large energy-consuming country, my country's energy consumption per unit of GDP in 2008 is 2.4 times the world average, 2.4 times, 4.4 times and 1.3 times that of the United States, Japan and India respectively. Most of this energy is consumed by the manufacturing industry. As the industrial mother machine of the manufacturing industry-machine tools, its ownership in my country ranks first in the world. The total rated power of machine tools is equivalent to about three times the total installed capacity of the Three Gorges Power Station. Energy consumption is huge, but energy efficiency and energy utilization are very low, and a large numb...

Most of these energies are consumed by the manufacturing industry. As the industrial mother machine of the manufacturing industry - machine tools, its holdings in my country rank first in the world. The total rated power of machine tool equipment is equivalent to about three times the total installed capacity of the Three Gorges Power Station. The energy consumption is huge, but the energy efficiency and energy utilization rate are very low, and a large number of investigations and studies show that it is less than 30%, and a large amount of energy is consumed to do useless work
