In this research, in order to optimize casting design of an automobile part (Gear Box), Computer Aided Engineering (CAE) was performed by using the simulation software (Z-Cast). The simulation results were analyzed and compared with experimental results. During the filling process, internal porosities caused by air entrap were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were predicted and reduced by the modification of the gate system. For making better permanent High Pressure Die Casting (HPDC) mold, cooling systems on several thick areas are proposed in order to reduce internal porosities caused by the solidification shrinkage.

In this research, Computer Aided Engineering (CAE) simulation was performed by using the simulation software (Z-Cast) in order to optimize casting design of an automobile part (steering wheel housing) which is well known and complicated to achieve a good casting layout. The simulation results were analyzed and compared with experimental results. During the filling process, internal porosities caused by air entrap were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were predicted and reduced by the modification of the gate system.

In a competitive and globalized business environment, the need for the sustainable product development becomes stronger. To meet these trends, the total cost during the product life cycle, called life cycle cost (LCC), should be considered as an important factor in new product development. In this paper, a hybrid life cycle cost model (HLCCM) is developed as a hybrid life cycle cost system (HLCCS) to estimate the cost performance of product design alternatives. It aims at improving the cost performance of products using genetic algorithms and artificial neural networks which consist of high-level product attributes and LCC results. The framework incorporated HLCCM is proposed in cloud computing based collaborative design environment and allows users to estimate the product data and other related information on a wide variety of application. This paper presents approximate LCC estimation of product design alternatives represented by solid models in cloud computing based collaborative design environment.

In this research, Computer Aided Engineering (CAE) simulation was performed by using the simulation software (AnyCasting) in order to optimize casting design of an automobile part (Oil Pan_7G9E) which is well known and complicated to achieve a good casting layout. The simulation results were analyzed and compared carefully in order to apply them into the production die-casting mold. During the filling process, internal porosities caused by air entrap were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were predicted and reduced by the modification of the gate system.

In present casting industries, product development paradigm is shifting from traditional trial-and-error to proof-of-concept based on CAE-enabled simulation. In the new production development paradigm, CAE simulation plays an important role because it models the entire casting process and reveals the dynamic behavior of the casting system in working conditions. In this research, Computer Aided Engineering (CAE) simulation was performed by using the simulation software (AnyCasting) in order to optimize casting design of an automobile part (Upper Oil Pan) which is well known and complicated to achieve a good casting layout. The simulation results were analyzed and compared carefully in order to apply them into the production die-casting mold. During the filling process, internal porosities caused by air entrapments were predicted and reduced remarkably by the modification of the gate system and the configuration of overflow. With the solidification analysis, internal porosities caused by the solidification shrinkage were also predicted.
