面向高端装备制造CAE技术的机遇和挑战

Opportunity and challenge of CAE technology for high-end equipment manufacturing

针对高端装备制造在设计、分析、制造、服役和维护等全过程中对CAE的需求,从结构、流体以及流固耦合等3个方面概述CAE技术国内外进展及其面临的机遇和挑战,指出在发展具有能够对装备在极端服役环境下准确的结构、流体和流固耦合CAE分析技术的基础之上,需不断突破面向工程应用的多物理场耦合、跨尺度分析、多学科综合设计、产品性能评估和集成等关键技术,使CAE逐步向支持现代设计和全寿命周期管理转变.

For the requirements to CAE in the whole process of the high-end equipment manufacturing in the design,analysis,manufacturing,operation,maintenance and so on,the progress of CAE technology in China and abroad,and its opportunity and challenge are reviewed and discussed from three areas,i.e.,the structure,the fluid and the fluid-structure coupling.It is pointed out that based on the developments of the CAE technology that meet the accurate analysis of structural,fluid and fluid-structure coupling for equipment in extreme service environments,the key technologies such as multi-physics field coupling,cross-scale analysis,multi-disciplinary synthetical design,product performance evaluation,integration and so on should be further promoted to enable CAE to support the modern design and full life-cycle management.
