【正文】 gorithm,there must be associativity between the CAD and FEA rational 4 behind this requirement is best explained using an the initial design stage when the engineer applies constraints on a particular surface of the FEA model。 1 外文原文 A Discussion on Modern Design Optimization The integration of optimization techniques with Finite Element Analysis(FEA) and CAD is having pronounced effects on the product design integration has the power to reduce design costs by shifting the burden from the engineer to the ,the mathematical rigor of a properly implemented optimization tool can add confidence to the design ,an optimization method controls a series of applications,including CAD software as well as FEA automatic solid meshers and analysis bination allows for shape optimizations on CAD parts or assemblies under a wide range of physical scenarios including mechanical and thermal effects. Modern optimization methods perform shape optimizations on ponents generated within a choice of CAD ,there is seamless data exchange via direct memory transfer between the CAD and FEA applications without the need for file ,if associativity between the CAD and FEA software exists,any changes made in the CAD geometry are immediately reflected in the FEA the approach taken by ALGOR,the design optimization process begins before the FEA model is user simply selects which dimension in the CAD model needs to be optimized and the design criterion,which may include maximum stresses,temperatures or analysis process appropriate for the design criterion,and,if necessary without any humen intervention,the CAD geometry is is taken such that the FEA model is also updated using the principle of associativity,which implies that constraints and loads are preserved from the prior new FEA model,including a new highquality solid mesh,is now analyzed,and the results are again pared with the design process is repeated until the design criterion is shows the procedure of shape optimization. Introduction The typical design process involves iterations during which the geometry of the part(s) is general,each iteration also involves some from of analysis in order to obtain viable engineering designs may require a large number of such iterations,each of which is costly,especially if one considers the value of an engineer’s principle 2 behind design optimization applications is to relieve the engineer of the laborious task by automatically conducting these first glance,it may ap
