激光器虚拟样机与物理样机方案决策研究

Scheme decision analysis between physical prototype and virtual prototype for laser

摘要: 对于具体激光器产品的设计,技术方案决策是一个复杂的过程,通常只能定性分析与逻辑判断,难以定量计算和分析。为此,采用层次分析法,以高功率横流CO2激光器为例,对其设计方案的决策作出一个精确的定量分析。通过对层次结构模型中措施层、准则层、目标层的分析,得出物理样机和虚拟样机两方案在准则层和目标层的数值对比关系,用数值计算结果为依据进行方案决策。结果表明,采用虚拟样机技术来研发激光器等比较特殊的产品具有物理样机无法比拟的优点。

Abstract: Technology scheme decision is a complex process for a real laser product.Usually,qualitative analysis and logical judgement are used in this process.It's difficult to analyze in quantitive way.With high power crosscurrent CO2 laser as an example,analysis of hiberarchy process(AHP) is used for decision process between physical prototype(PP) and virtual prototype(VP) in a quantitive way.Through analyzing mearusures,criterias and target in hiberarchy,the quantitive comparative relation between PP and VP in criteria layer and target layer are obtained and it is used to make shceme decision.Results show that it's better for laser development with PP than VP.
