| | It put the merit and way do the system design based on the new general system design idea. It also tell the key technology of the product design system in extranet and different platformdistributed computer model?multiclass complex recursive construction view model and its implement ways. | | 阐述了新一代系统设计思想 ,重点讨论了在 Extranet和跨平台环境下复杂机电产品设计系统的关键技术分布式计算模型、多分类复合递阶结构视图模型及实现方法 . | | 文摘来源 | | The paper describes an automatic on_line detecting system which can detect inner parts of complex electromechanical products. In the system,digital image processing technology is used to preprocess X_ray images of the products, and neural network algorithm is applied to diagnose faults. The fault recognition model adopts an improved back_propagating neural network, which is trained by a series of standard X_ray images of correctly assembled products.During the process of detection, two images of objects in ... | | 针对复杂的机电产品内部构件状态检测这一工程难题 ,本文介绍了一种自动在线检测系统。该系统采用X射线对产品成像 ,运用数字图像处理技术对射线图像进行预处理 ,由神经网络算法进行故障诊断。故障识别模型采用了改进的BP神经网络算法 ,以正常装配状态时的多幅图像经预处理后作为学习样本训练BP神经网络。检测时一般只需拍摄两幅不同方位的图像 ,经预处理后输入神经网络与样本图像进行比较判断 ,即可识别出关键元器件的状态。该系统将数字射线成像技术和图像处理技术相结合 ,并在故障识别算法中采用了神经网络算法 ,提高了产品故障的检测速度和可靠性 ,在工业无损检测领域具有一定的实用性。 | | 文摘来源 | | As the modeling of mechatronic product simulation is completed often in manner of centralization, a new distributed collaboration modeling method was given. First analysed the information which are necessary for distributed collaboration modeling, then made use of the distributed object technology to integrate them into distributed simulation model object. The distributed simulation model object not only can be correctly assembled and re-used with its plenty of information, but also can be accessed transpar... | | 针对目前复杂机电产品仿真通常只能集中建模的现状,提出一种新的分布式协同建模方法。首先分析了支持分布式协同建模所必需的信息,然后利用分布式对象技术,将这些信息集成为分布式仿真模型对象。分布式仿真模型对象通过包含的丰富信息,支持能够被正确的组装和重用;通过自身的分布式特点使得建模人员能够透明访问它们。基于分布式仿真模型对象的分布式协同建模方法能够强有力支持复杂机电产品的分布式协同建模。 | | 文摘来源 | |   | | << 更多相关文摘 |
