系统工程方法和价值准则在光电产品设计中的运用

 以系统工程方法论述光电产品技术设计的特征、内容及方法，阐明基于价值准则的优化设计分析决策法，叙述在光电系统开发设计阶段采用VPD(Virtual Product Development)技术实现光电产品全数字化拟实平台的方法和过程。在开发某光电跟踪测量产品中立足于系统工程方法结合VPD技术，使设计师利用模型与仿真技术可获得产品的概念形成、设计、制造到实现全过程的三维可视和可交互的产品集成开发环境。通过将VPD与实践经验相结合，并以数字化主模型为依托，开发出“屏幕样机”，进而对其展开动力学模型辨识等仿真试验，实现了从过去的经验设计方式跨越到预测设计方式，完成了虚拟制造驱动设计全过程。

Application of systematic engineering method and value criterion

The characteristics, contents and methods of the design of optoelectronic products were discussed by using systematic engineering method, and the optimization design analytic decision based on the value criterion was described, as well as the method and process for achieving the full digitalized simulation platform of optoelectronic product by utilizing the virtual product development (VPD) technique in the design phase of the optoelectronic system development. An optoelectronic tracking and measurement product was developed based on the systematic engineering method in combination with the VPD technology .By using models and simulation technique the designer obtained the 3-D visual interactive integrated development environment for the concept formation,design, manufacture and realization of the product. Combining VPD with the practical experience and according to the digital main model, the virtual prototype was designed and the simulation tests such as identification of dynamic model were carried out. The forecast design was achieved substituted for the experience design to finish the whole process for virtually-manufactured driver designing.
