[Abstract]:In order to achieve efficient custom-made product design and ensure the quality robustness of the final structure, this paper puts forward the structure layout and optimization technology of custom-made product from the point of view of the structural layout design, the optimization of the selection and the multi-performance simulation of the custom-made product. The main contents of this paper include the following six aspects: the first chapter describes the research status of customized product layout solution and case selection technology, analyzes the existing problems of related technologies, and introduces the research background of this paper. The research content and organization structure of this paper are given. In chapter 2, we analyze the Petri relation network of customized product function decomposition and the polychromatic model of product layout, and realize the mapping from the principle scheme of customized product to the structure layout. Firstly, the functional decomposition model is constructed based on Petri nets, and then the mapping between function-motion allocation and layout modules is carried out by using FBS mapping technology, and the layout meta-Petri relation network is obtained. Secondly, the mathematical description of the customized product layout meta-Petri relation network is given by using the uniform colors in the polychromatic set and the individual color. The multi-color model of the product layout is formed, and the corresponding algorithm for solving the layout constraints is proposed. Finally the mapping process between function-motion assignment and layout modules in customized product structure layout is described by applying the reasoning principle of uniform color and circumscribed Boolean matrix between individual colors. On this basis, a method for solving layout constraints of customized product polychromatic model based on Petri net is proposed. In the third chapter, the effect of case selection on the robustness of customized product quality is analyzed, and a customized product selection model is constructed. Based on the quality loss function of Taguchi theory, this paper introduces the robustness of the signal-to-noise ratio (SNR) representation module, synthetically considers the connection form and assembly deviation of the module, and establishes the module case robust selection model for modular products. The method of solving the model is also given. On the basis of this, a method of selecting and optimizing customized product modules based on quality loss function is proposed. In chapter 4, the detailed process of simulation analysis of customized products is described, and the method of simulation analysis based on component is proposed, and the formal form of simulation component is described at the same time. Then, the performance simulation results are analyzed based on the customer satisfaction analysis method, and the simulation results are judged according to the conditions of the satisfactory solution. Finally, the static and vibration characteristics of the key components of the high-speed elevator are simulated. In the fifth chapter, according to the theory and method proposed in this paper, the elevator product structure layout and optimization system is developed. In the sixth chapter, based on the summary of the research content and related research results, the future research direction of the subject is prospected.
