In precision machining of complex curved surface parts with high performance, geometry accuracy is not the only constraint, but the performance should also be met. Performance of this kind of parts is closely related to the geometrical and physical parameters, so the final actual size and shape are affected by multiple source constraints, such as geometry, physics, and performance. These parts are rather difficult to be manufactured and new manufacturing method according to performance requirement is urgently needed. Based on performance and manufacturing requirements for complex curved surface parts, a new classification method is proposed, which divided the complex curved surface parts into two categories: surface re-design complex curved surface parts with multi-source constraints(PRCS) and surface unique complex curved surface parts with pure geometric constraints(PUCS). A correlation model is constructed between the performance and multi-source constraints for PRCS, which reveals the correlation between the performance and multi-source constraints. A re-design method is also developed. Through solving the correlation model of the typical paws performance-associated surface, the mapping relation between the performance-associated surface and the related removal amount is obtained. The explicit correlation model and the method for the corresponding related removal amount of the performance-associated surface are built based on the classification of surface re-design complex curved surface parts with multi-source constraints. Research results have been used in the actual processing of the typical parts such as radome, common bottom components, nozzle, et al., which shows improved efficiency and accuracy of the precision machining for the surface re-design parts with complex curved surface.  相似文献

二次城市设计的任务是在总体设计和控制性详细规划的基础上,在确定了某些前提要素的情况下,在人工环境和与之相关联的环境要素不断变化的过程中,重新建构城市新区的形态环境.目前,我国城市新区建设中的城市设计项目进行国际咨询后,中标深化方案的设计指引与现实建设开发中地块项目型城市设计实施相脱节,造成咨询方案不具备可实施性,二次城市设计可从过程性和可调性两方面解决以上问题.  相似文献

Focus groups have traditionally been used in market and design research to obtain group reactions to product concepts. In this article we outline a simple methodological extension to this format, involving a further stage of concept re-design in smaller subgroups facilitated by a professional designer. The method was developed in the context of working with groups of older people on concepts addressing memory, identity and social communication. It is illustrated with reference to the re-design of two seeded concepts and feedback from participants themselves on the experience of taking part.  相似文献

The adaptive input design (also called online redesign of experiments) for parameter estimation is very effective for the compensation of uncertainties in nonlinear processes. Moreover, it enables substantial savings in experimental effort and greater reliability in modeling.We present theoretical details and experimental results from the real-time adaptive optimal input design for parameter estimation. The case study considers separation of three benzoate by reverse phase liquid chromatography. Following a receding horizon scheme, adaptive D-optimal input designs are generated for a precise determination of competitive adsorption isotherm parameters. Moreover, numerical techniques for the regularization of arising ill-posed problems, e.g. due to scarce measurements, lack of prior information about parameters, low sensitivities and parameter correlations are discussed. The estimated parameter values are successfully validated by Frontal Analysis and the benefits of optimal input designs are highlighted when compared to various standard/heuristic input designs in terms of parameter accuracy and precision.  相似文献
