In this study, an adaptive optimization method based on artificial neural network model is proposed to optimize the injection molding process. The optimization process aims at minimizing the warpage of the injection molding parts in which process parameters are design variables. Moldflow Plastic Insight software is used to analyze the warpage of the injection molding parts. The mold temperature...

Injection molding is the most common manufacturing process for production of high volume commercial parts. However, injection molding is characterized by extremely complex process dynamics and material properties, which make it difficult to understand and predict the product quality and can lead to numerous unacceptable quality defects. There are many solutions to these problems – Moldflow is r...

abstract: in this paper, the results of experimental and numerical simulation of low velocity impact process have been carried out to investigate energy absorption of composite sandwich panels with 3d woven fabrics of glass fibers and epoxy resin. for this purpose, diagrams of force-displacement of the quasi-static and quasi-dynamic impact tests were studied. for the finite element simulation, ...

Abstract The three-dimensional model of the automobile rearview mirror is made in three steps. Firstly, a non-contact 3D laser scanner used to obtain point cloud mirror, and then Image ware denoise cloud, construct lines from points, grid lines. Finally, poured into software for surface reconstruction, product redesigned. After obtaining Moldflow further simulate injection molding process. runn...

An easy-to-use modeling environment for numerical geothermal reservoir has been developed for TOUGH2 simulator. It consists of pre-processors to prepare text-based input data, post-processors to visualize simulation result, and databases to store observations and information related to wells. These software have interactive graphical user interfaces for easy operation to develop numerical geoth...

cylindrical thin-walled tubes due to construction and easy installation, high energy absorption capacity are used in the automotive industry as an impact energy absorber. however, the main weakness of cylindrical tubes is in the high initial peak load. therefore, in this paper, to overcome this weakness, a buckling initiator is used at the top of the tube. this buckling initiator is a steel rod...
