Modeling Software

The geometric models of the hydraulic turnover device are constructed by using three -dimensional modeling software UG, and then they are induced into simulation software ADAMS by a sharing data format. By using ADAMS, models are further simplified and the virtual prototype is established. By using the associated model, the simulation of the hydraulic turnover device is analyzed in ADAMS. Compared with the traditional methods of using physical prototypes, the movement processes and relevant parameters of the hydraulic turnover device can be effectively obtained by means of this method. Furthermore, the quality of the constraint relations between the parts is very important in terms of the accuracy of the model simulation analysis. This simulation results accord with the practical situation, which indicates that the operation is stable and the efficiency is high. It provides a theoretical basis for the practical design of the hydraulic turnover device, which shows that the combination of ADAMS and UG works well.

The building information modelling (BIM) methodology supports collaborative works, based on the centralization of all information in a federated BIM model and on an efficient level of interoperability between BIM-based platforms. Concerning the structure design, the interoperability capacity of the most used software presents limitations that must be identified and alternative solutions must be proposed. This study analyzes the process of transfer of structure models between modeling and structure analysis tools. Distinct building cases were performed in order to recognize the type of limitations verified in the transfer processes concerning two-way data flow between several software. The study involves the modeling software ArchiCAD 2020, Revit 2020, and AECOsim 2019 and the structure analyzes tools SAP 2020, Robot 2020, and ETABS 22020. The transfer processes are realized in two ways: using the native data format; using a universal standard data transfer, the Industry Foundation Classes (IFC) format. The level of maturity of BIM in structure design is still relatively low, caused essentially by interoperability problems, but despite the limitations detected, this study shows throughout the development of several building case, that the methodology has clear advantages in the development of the structure project.

The use of conventional machining processes has been subject to important decline probably due to the increment in the use of emerging technologies. Therefore, the main applications of these traditional processes, such as automotive industry, are in crisis. In order to have a chance to compete successfully in the new trends, the machining industry must meet the needs of alternative sectors such as biomedical field. The aim of this study is to prove the capacity of micro-milling, by machining complex micro-cavities on aluminum workpiece using a conventional milling machine. Results are obtained by evaluating accuracy and geometric features. This study finds that the feed per tooth is a significant factor in order to obtain better results. The use of coolant increases the tool wear and therefore dimensional errors. This scope is a potential opportunity to reutilize the conventional machines from a new approach.
