Abstract

Now, with the rapid development of economy and the rapid growth of population, water, land and mineral resources of energy will become more and more serious lack of. Urgent need for energy conservation and environmental protection. This means vigorously develop recycling economy, speed up the construction of a conservation-oriented society demands it is particularly important and urgent. Green is re-engineering the entire life cycle of product design and management as a guide, high quality, highly efficient, energy-saving and environmental protection as the goal. To use advanced technology and industrial production as a means.Waste products for the restoration and improvement measures such as a series of technical and engineering activities collectively. It is the development of recycling economy and builds a conservation-oriented society one of the important ways.Products to create the feasibility and feasibility of further development of manufacturing industries are the primary problems faced by. Especially value-added products (human, energy, and so on) are the key parts could be restored without the need for replacement. Parts failure is the main form of fracture, corrosion, wear and deformation, among them, wear, corrosion, deformation are more intuitive or easy to detect, only fault caused the fatigue life difficult detection. Therefore research to products made in key parts residual fatigue life and the re-manufacturing of the products of China’s manufacturing industries to the development of important significance.This paper re-manufacturing parts on the residual fatigue life prediction, as well as its manufacturing of another two. To create a shield machine knife set as an example residual fatigue life prediction. Cutter to shield machine as an example of products to create integrated assessments. Use the mechanical design module Machine Design of CATIA to create EPBΦ6.28 of earth pressure balance knife-shield machine model. The analysis of the software used by the Analysis & Simulation automatic mesh and finite element analysis modules.Remanufacturing Parts fatigue life assessment method. Stretching through the standard sample, fatigue testing, and access to estimate material properties; through geometric modeling, dynamic simulation was loading. Finite Element Analysis was by the local stress, finally will be the material properties, loads and the local stress into the corresponding fatigue damage model, Most will be able to predict fatigue life of components. On the development based on the finite element model of the fatigue life prediction. Using knife-shield machine verified by the fatigue life prediction model of practicality. This paper analyses the special status under the knife disk loading, finite element analysis of static and dynamic mechanical, get the local stress.The product to create a reasonable assessment, Determine whether a product suitable for further manufacturing, At the same time production plan for the venture arrangement, production management provided the preconditions for. In this paper, the product has been scrapped to create assessment and product design to create assessment on the basis of the analysis. Proposed a combination of these two methods to create the assessment system. This follow-up to production and business management provided guidance of views. Shield machine set against knife to create, with Guangzhou Metro Line 4 Komatsu shield machine used to manufacture as an example, Using Data clear shield machine set to create the knife and comprehensive evaluation process. To develop a feasibility analysis to create guiding significance for other product design and manufacturing process. For similar products and further optimize the manufacturing process as a reference
