At present, many domestic manufacturers of the seats still in use Biography Serial production of the EC, that is, the design kind of processing test to improve the design of a single cycle. Led to the design of high cost and long development cycle. The event of failure of product quality, usually taken to increase the diameter of the blind or the thickness of the wall approach, rather than from the perspective of optimizing the overall structure to modify the design. Although this 本科生畢業(yè)設(shè)計(jì)（論文） 34 approach enables the weak part of the performance of seat change, it often will seat strength and stiffness of large margin, resulting in unnecessary waste of materials, Strength to the seat assembly as an example, the requirements of our standard seat assembly can withstand 20 times the gravity of the load assembly, the German standards are required to withstand 60 times the load of gravity. The impact of China39。s automobile industry, the design of seat work backward. Strictly speaking, the seat of our study was from the 20th century, the beginning of the eighties. After almost 20 years, currently chairs a number of manufacturers will be able to model a lot of domestic production support. With the advantages of joint ventures, domestic producers have a number of seats in part of the seat design and production technology, but still rely on foreign technology strength, selfdesign is still parked in the left at the starting stage. Caused by the design of China39。 D enterprise as a result of inadequate attention to the seat, has yet to carry out specific research, not only to the seat of the security risks, and constraints the development of the seat. With the modern car design to security, the pursuit of environmental protection and energy conservation, while ensuring the safety of car seats on the basis of the structural design of the seat abroad have also begun to lightweight, lowcost development, a growing number of new manufacturing technology and the start of lightweight material widely used in modern car seat design, therefore, our study of the safety seat technology in urgent need of a large number of inputs, thereby reducing the gap with the advanced level, developed for the status quo of China39。s seat of an important factor. At present, many domestic manufacturers of the seats is still the linkage of traditional modes of production, resulting in the design of high cost and long development cycle. Once the quality of products and unqualified, the blind tend to take greater diameter, wall thickness or the thickness of the solution, rather than from the perspective of improving the overall structure to modify the design. Although this approach enables the weak part of the performance of the seat has changed, but the strength and stiffness will seat large margin, resulting in unnecessary waste of materials, potentially increased the cost of the product design meeting also reflected backward chair design means supporting research. There are still a lot of seat design and the manufacturer does not have a high standard of technology supporting the use of puteraided design and analysis, can only follow the traditional design methods and processes, but also for the safety seat is only the awareness of regulatory requirements remain in the country on, hindered the development of seat design. China39。s automobile industry, the design of seat work backward. Strictly speaking, the seat of our study was from the 20th century, the beginning of the eighties. Experienced 20 years of development, currently has a lot of seat manufacturers. With the advantages of joint ventures, some of them with the design and production technology, but mainly rely on foreign forces, their own design and R amp。 loglog(x,y) 本科生畢業(yè)設(shè)計(jì)（論文） 32 附 錄Ⅱ CAR SEAT OF THE STATUS QUO AND DEVELOPMENT TREND Study abroad is acpanied by the seat of the birth of the car and started going through the hundredyear history, the development of a very mature, with the seatrelated safety standards and regulations have been perfect. As early as age 60 in the 20th century, many foreign countries have developed national or industry on car seat safety performance to ensure that the various regulations and standards, such as the United States to enforce laws and regulations of the Federal Motor Vehicle Safety (FMVSS) and industrial and mercial equipment manufacturers association (BIFMA) and other nonmandatory laws and regulations, and developed a wide range of special test equipment.
