Auto parts will become the development trend of green manufacturing design - News - Business News

Of modern product development process must take into account the entire product life cycle design, conduct full-life cycle management of. Total Life-cycle management must consider not only the first half-products: feasibility studies, design, manufacture, but also to consider the product, after half a lifetime: the use, maintenance up to withdraw from active service and waste management.Foreign automobile manufacturers have formed a green sizeable industry. The U.S. Society of Automotive Engineers (SAE) has hosted a "life-cycle management" and "re-create" the theme of academic meetings. The major car companies also attaches great importance to the recovery of vehicles and manufacturing. The country has many units are being re-manufacturing research in the field, it is still in its infancy.Traditional design and green design comparisonTraditional design is green design. Green design is the development of traditional design to supplement and complete. Only in the use of trad itional design based on the design goals of environmental properties of the product design but also as one of the goals in order to make products designed to meet the performance requirements of green, with market competitiveness. Both in the design basis, design, design process, designed in such aspects as there is a big difference in comparison between the two, as shown in Table 1. The traditional manufacturing model of the product life cycle.Green Manufacturing Engineering in Automobile IndustryAutomotive Manufacturing Engineering Green then be able to make technological transformation of automotive products, and to differentiate between the parts as scrap or as a re-manufacturing of recycled materials, rough, while the use of advanced surface engineering technology or rapid prototyping technology make it back to life, get more high-performance car and then manufactured products, automotive products, it is the second investment is an important measure for the appreciation of automobile products.The traditional life cycle of a carThe traditional life cycle of a car is a demonstration, design, manufacture, use, into the retirement date, its logistics is an open-loop system. The 2l century, the green car's entire life cycle "from development to regeneration", namely the use of vehicles passed after the end of life recycling renewable or manufactured to be transformed so that the life of scrap vehicles multiplied extended its logistics is a closed-loop system.Engine costs account for an important part of the total cost of vehicle, its implementation remanufacturing has important practical value. Remanufactured engines are not a simple repair on the old engine, but the old engine rigorous testing and re-manufacturing. Remanufactured engine is currently the main buyer focused on the private car owners, taxi drivers, small business owners, etc., for the price sensitive user groups. Shanghai Volkswagen's special service stations, through the Nationa l Recovery can be used to re-create the old engine, remanufactured engine products also flows through special maintenance station users, relying on a strong network of service stations special support for the maintenance of professional and high quality services, so that in the Manufacturing engine users to establish a good image.The automotive product life cycle model of recyclingAuto parts recycling typically include: (1) direct use; (2) maintenance after use; (3) three forms of re-manufacturing. In accordance with spare parts in the product life cycle, the cycle can be established for the product life cycle, recycling model.Recycling-oriented design methodsRecyclable product design is in the product design stage to fully consider the possibility of parts and materials recovery, recycling value of the size, recovery and treatment methods, such as recycling and recovery of structure and technology of a range of issues related to the final part material resources to achieve optimum utilization of and energy loss of the smallest, and environmental pollution, the smallest of a design idea and method.Detachable design for recycling is an important design methods. It requires the design in the product structure, change the traditional connection methods and replace them with easily removable connection mode. Removable structural design, there are two types: one is based on the maturity structure of connection methods, such as bolt connections, key links and the interference fit, etc.; the other is the purpose of computer-based design methods.Design method for disassemblyThe design for disassembly is one of the main elements of green design, requiring the initial stages of product design for disassembly will be one of the objectives of structural design as shown in Figure 6.In short, recycling and product-oriented design is not a removable product assembly design of a simple reversible process, should gradually establish a suitable CAD / CAM and DFD of a unified information model, and to enable them to automatically generate parts of the assembly, disassembly, etc. optimal sequence, in order to facilitate concurrent product-oriented, integrated life-cycle-oriented design.Green manufacturing engineering is a kind of ecological and economic needs to adapt to the recycling of the form of green manufacturing engineering to introduce a vehicle to solve the problem of waste vehicle caused an important means of social pollution, their considerable part of the waste by re-manufacturing components can be reused later; while The other - some waste material in the form of components Zeyi comprehensive recycling. Green cars re-manufacturing engineering for resource conservation and environmental protection, promoting social, economic and environmental development is very important and long-term practical significance.
