United Kingdom from 60’s, on national policies and financial resources to support the development and promotion of innovative design。 (13) Crane dynamic (fatigue life analysis of) the extensive application of research results. Truly innovative design is the design of the various methods and techniques of organic position and utilization. Design work has never been isolated, the resulting technical and management related issues: From the PDM, CAPP, ERP, PLM to the whole process of CRM management of closedloop feedback。 (9) Very short delivery time requirements parallel design and concurrent engineering design。 (5) The introduction of new highprecision weighing sensor technology and positioning systems crane design。大連 科技 學(xué)院 2020 屆本科生畢業(yè)設(shè)計(論文)外文翻譯 1 Crane innovative design Prospects 1 Outline With the new century, new patterns of global industry changes and the level of China’s rapid development of industrial technology, Innovative design has drawn increasing attention to institutions and enterprises. Crane also extremely active market in recent years up to the crane design, no doubt brought a higher level of development requirements, crane innovative design has bee the most important enterprises to improve petitiveness means and ways. With the rapid development of modern puter control technology to make prehensive consideration of the design of crane control system reliability, operation fort, organization and structure, there have been generalized optimization demands a higher level, Cranes must be designed so the conventional design from the original model e out with new ideas, new principles, new methods, new technologies and new techniques to design new products to adapt to new situations, creative design issues have been placed in real designers in front of the crane. Crane innovative design theories, methods and tools are based on modern design theory and method, applied microelectronics, information, management and other modern scientific techniques to improve product quality, customer satisfaction, price and style, improve product features, shorten product development cycle for the purpose of the relevant work done. Crane innovation theory, method and technology research aim is special equipment from the crane as required by the work of security and reliability objective, in particular technical, economic constraints, the plete lifting of the innovative creative design, to the delivery and performance requirements to meet the users premise to achieve the best mix of technical and economic. According to reality and development, design means more and more reflect the precision, automation, virtualization and fast characteristics. Modern crane products are toward the mechanical and e
