United Kingdom from 60’s, on national policies and financial resources to support the development and promotion of innovative design。 Germany proposed design is science, to design the development of science has reached a considerable scale。 The United States set up the Planning Board Japan also attaches great importance to the development of design technology will be designed as a technical, economic, aesthetic, and the overall integration of ergonomics, and strongly promote and adopt new technologies. In short, the economic and technical design of the developed countries and a lot more attention to innovative design, making the mechanical and electrical products, including lifting the product design, safety and reliability, technical and economic aspects of such rapid changes occur more and more design increasing levels. The development of China’s crane design has gone through a tortuous process. More than before the design is based on imitation of the Soviet Union mainly, with the designer’s experience, a great product design limitations. From the 60’s, started a new product development and design of new ponents and experimental research, to make the design experience from design imitation and gradually to experimental research and analysis phase. To 80 years, BaoGang and some very large panies with foreign crane and with the introduction of foreign joint design, manufacturing, and other forms of domestic adoption, begin in the country to introduce a number of international advanced technology and design. The same time, puter application technology into design, design work on the crane played an important role in promoting development. However, our crane design are still many problems, primarily the design of most small and medium analysis is not enough, low capital investment, personnel training, keep up with development needs, has not formed to develop new products or old products, design and ability to cope with the introduction of advanced technologies and products, not from a design perspective digestion, and no ability to reinnovation. Designers do not form a reasonable echelon。 the product is still the same kind for several decades, so far, the copy from the mode of existence, not their intellectual property, only the contract brought in to cope with low price. A few large enterprises in the innovative design of rapid development, the domestic 大連 科技 學(xué)院 2020 屆本科生畢業(yè)設(shè)計(jì)（論文）外文翻譯 4 design capability and level of cranes and the advanced design phase to shorten the distance. These enterprises have a large number of new puter technology, already popular twodimensional CAD, 3D design has been extended. ED and other electrical design using advanced design tools, the introduction of the stator voltage regulation and frequency control, PLC system control involved using a large number of hightech sensing devices, to achieve a positioning accuracy, easy operation, is also gradually increase its security and reliability. Through the application of expert systems, greatly advanced the process of innovative design and use of system theory and information theory and other modern puter application technology research results and have made innovative design crane began to intelligence direction. Reduce design, procurement and production costs Domestic and foreign experts on the cost estimates and methods to reduce costs a lot of research, some enterprises in program design, and quotation system such as the work of the results achieved to some extent. German scholars of the cost structure and classification, with the relative costs of different design concept to realize the contrast between the evaluation， At the same time using the design methodology and design of cost control features of cost and design features of the transformation between the proposed objectives of cost accounting of useroriented。 Ameri
