Research On Quality Control Method In Process Of Complex Products Remanufacture

Stage of complex mechanical product remanufacturing environment is complicated, the actual working conditions to make different types of equipment, spare parts number and status, quality of all kinds of uncertainty random disturbance factors occurred frequently, all kinds of parallel devices and constraint conditions has increased dramatically, making all kinds of complex mechanical product quality attributes in the process of remanufacturing and change constantly fusion, parts status, method of repair, processing and assembling process with high randomness and uncertainty, complex mechanical product disassembly, cleaning, detection, classification and manufacturing process or upgraded, assembly and testing process quality control points of each present a strong dynamic correlation, multiple constraints, such as highly nonlinear characteristics. So the suitable for complex mechanical products remanufacturing environment quality control strategy, is to improve the complex mechanical products manufacturing process quality stability and reliability of key again.Again based on the complex mechanical product manufacturing quality stability and reliability analysis of the related factors, in view of the complex mechanical product remanufacturing process affect the product quality stability and reliability of error and deviation, etc., to study the nonlinear coupling, and product component degradation competition mechanism and remanufacturing product quality of error and bias flow forming law; Differentiate from system level, the quality control field, implement quality attributes to form different types of quality control points in the process of transmission, the accumulative regularity of explicit quantitative expression, for the remanufacturing quality control points in the process of dynamic error and deviation compensation offer policy support; Based on local monitoring feature mapping network (RSFM) and simulated annealing genetic algorithm, starting from initialization allocation quality control field, instantiate the remanufacturing quality control point, step by step synchronous measurement, collection, processing and manufacturing quality of the experimental data, launch quality control field redistribution mechanisms, for real-time working condition of manufacturing quality information to respond to online quality evaluation, the fast solving and manufacturing quality control field distribution model, online optimization implementation quality control points; Finally USES rule-based expert system, combining with the MES theory and method of using expert knowledge and inference rules for reasoning, research the remanufacturing quality control strategy information database and platform technology, manufacturing quality control system and the remanufacturing process quality information to trace and control strategy, in order to remanufacturing enterprises improve the quality of complex mechanical product stability and reliability to provide support.
