can scholar (the quotation of prices in the face) on the existing or produced products for return of the survey results, the establishment of a cost model。 Japan, Switzerland, the United Kingdom and other scholars have estimated the cost of the manufacturing stage had more of. However, research funding and manpower shortage, workload and difficult reasons, progress has remained slow. Many scholars country on this subject for several years of research, DFC and DTC proposed research model, pleted the prehensive analysis and parison of the single series of crane design standards and design objectives of the cost of prehensive evaluation system. But the data accumulated amount is less, less practical scope. Can be seen from the above, the design of the product cost reduction has also been a long time to stay in the local phase of the analysis and calculation, has not yet put it into the design process through the integration of CAD system, and did not introduce the concept of product life cycle , resulting in mostly qualitative analysis, quantitative analysis is based on a small number of limited data, based on statistical analysis, Therefore, the establishment of the whole process designed especially to support the initial design phase of the program and the cost of the overall structure of the information model has been the key to achieving lowcost design and the urgent need to address the problem. Innovative design of the Rapid Response 大连 科技 学院 2020 届本科生毕业设计（论文）外文翻译 5 Tokyo International Conference in 1992 formally proposed concurrent engineering technology, developed as the basis to reduce the design period of rapid design techniques (RDT), Current international design in parallel for rapid design, rapid prototyping, serialization modular technology and the development of virtual manufacturing technologies are relatively fast, but crane industry has not been largescale popularization and application. Simulation and Virtual Design Study abroad are more active, the simulation of mechanical product design modeling, including the current most widely used finite element method (FEM), finite difference method. Simulation technology is increasingly widely used, so that it can overe the physical space and time constraints. Digital prototype simulation designed crane products on large and plex program evaluation。 review of agency action principle, the structure interference check is of great practical significance. At the same time in the puter virtual reality system (VRS) in the virtual design environment (VD) for technical studies also began to receive attention. Intelligent design The major industrial countries are from traditional CAD technology continues to intelligent CAD (ICAD) and the direction of manmachine intelligent design system, electrical control system from the analysis, selfadjusting, selfcorrection, intelligent level increased, which make cranes the whole process of design and use of automation and intelligence can be achieved. Optimal Design of Generalized Home about numerical optimization techniques applied to engineering design early 70s, and the current discrete and random variable optimization, structural optimization, intelligent optimization, optimization modeling and optimization of plex systems research methodology has been made in the fields of theory and a considerable level of application of the results, But extended to the forward modeling, processing model, backward extended to the whole process of optimization results show that lack of research indepth and prehensive, and there is a certain gap between the major industrial countries. China crane design parameters on the sensitivity analysis and optimization of the specific application of generalized also achieved initial success. 3 Objectives and key content and direction Target Research and product innovation to grasp the theory and method, and applied to a 大连 科技 学院 2020 届本科生毕业设计（论文）外文翻译 6 number of focused product design, improve product design capability and level of integrated, so that crane products in the product quality, price, delivery and function of type (shape color) and so on to meet the evolving needs of users, in the fierce market petition take more share. Main contents Innovative design techniques Type carried out on the crane drive innovation, structures and functions of innovation theory and technology innovation base in theoretical research, we analyze the new material, new techniques, new gear, and thus through the optimization of different design, deposition and bination to prod。
