3D Information

<p>Building information modeling (BIM) is a new technology in the bridge construction industry. 3D models can provide perfect numerical expression of drawings from design results. 3D information models for bridge structures improve design quality in terms of accurate drawings, constructability, and collaboration. However, there are lots of challenges to apply these techniques to actual bridge projects. For instance, bridge engineers are facing the challenge of making the vast information generated by their structural model useful for professionals further down the line in the lifecycle of the bridge. Contractors and inspectors require a 3D model which is created after the design process to add extra information related to activities and store that information in the same model. In this paper, technologies available to generate, manage, and enrich the bridge 3D model with intelligent information from construction to design and inspection are proposed.</p>

The inlet deflection angle is an important blade design parameter with respect to both performance and manufacturability of torque converters. This study investigated the influence of the inlet deflection angle on the performance of torque converters and a method of optimizing the inlet deflection angle for torque converters based on 3D flow simulation is presented. Parameter analysis and multi-objective optimization were performed on an automated 3D flow simulation platform. The results indicate that the mass flow rate increases with a decreasing difference between the pump outlet deflection angle and the turbine inlet deflection angle, consequently increasing pump capacity factor. The advantages of the method proposed are an improved design quality and a significantly shorter design cycle.

Researchers especially from engineering field are using Computer Fluid Dynamic (CFD) software to simulate the three dimension (3D) model before they perform any experiments to prove their theories. The aim of this study is to develop a valve model in 3D using Solidworks software and to analyze internal fluid flow using Solidworks Flow Simulation (SWF) software to prove that this software has the capability in performing fluid simulations for the ball valve. The SWF successfully calculates the value of outlet velocity for the ball valve at different closing angles and different pressures value. The results shown are significantly acceptable by referring to the outputs of practical experiment and simulation incidence’s error of Ozdamar model 2007. The average error in calculation for SWF is about 7.42%, unlike FLUENT which is around 11.09%. Therefore; the engineers can simulate their models with higher accuracy using SWF software.

With large-scale development of ultra high-transmission network, the structure of transmission line-towers system tends to the tower higher, the cross-section of transmission lines larger and span between towers longer. As the increasing of transmission lines voltage grade, transmission line-towers system has higher requirements on static and dynamic stability. It is difficult for traditional design method to meet the demands of new transmission line-towers, not to mention shorten the design cycle, improve design quality. In this paper, we establish overhead transmission line-towers system model based on parameterized finite element method, by gradually increasing the thickness of the icing, iced load, wind load, weight, mechanical properties under the action of the load and the conductor tension. The analysis results show that the model can effectively reflect the mechanical properties of the transmission towers, and improve the quality of the design, greatly shortening the design cycle.

A fluid simulation calculation method of the microfluidic network is proposed as a means to achieve the flow distribution of the microfluidic network. This paper quantitatively analyzes the influence of flow distribution in microfluidic devices impacted by pressure variation in the pressure source and channel length. The flow distribution in microfluidic devices with three types of channel lengths under three different pressure conditions is studied and shows that the results obtained by the simulation calculation method on the basis of the fluid network are close to those given by the calculation method of the conventional electrical method. The simulation calculation method on the basis of the fluid network studied in this paper has computational reliability and can respond to the influence of microfluidic network length changes to the fluid system, which plays an active role in Lab-on-a-chip design and microchannel flow prediction.

This paper presents a knowledge-based system capable of giving the designer quality support when making decisions from the aspect of modeling the reinforcement of a plate-press within a position of maximum compressive load, and by choosing suitable material for the plate. Based on the selected combination of reinforcement and material, this system acquaints the user with the size and position of the largest comparative stress, and the greatest nodal displacement in the load-direction. This system operates based on the implemented knowledge of experts in the execution of design, material selection, and numerical analysis based on the finite-element method (FEM), which was written with the help of parameters within the knowledge-base of the CATIA V5 CAD-system. Using this system gives the user an opportunity to reach conclusions that are crucial for designing a plate-press or pressure-loaded die-elements, in general. The results reveal that the system can dramatically shorten design time and improve design quality in comparison to manual design process.

ABSTRAKValve adalah alat mekanis yang mengatur aliran atau tekanan cairan. Fungsinya adalah  menutup atau membuka aliran, mengontrol laju aliran, mengalihkan aliran, mencegah aliran balik, mengontrol tekanan, atau mengurangi tekanan. Masalah yang umumnya ditemui adalah  penutupan valve tidak sempurna dikarenakan adanya kotoran-kotoran yang menghalangi penutupnya untuk menutup secara sempurna. Penanganannya yang paling sederhana yaitu membersihkan dudukan dari kotoran-kotoran tadi secara intensif dan dilakukan pelumasan. Penelitian ini bertujuan untuk menjelaskan gambaran tentang simulasi aliran pada ball valve dan butterfly valve. Dan menjelaskan perbandingan tekanan, temperatur dan kecepatan distribusi air pada dua jenis valve. Tekanan fluida pada kondisi tertutup berbeda dengan kondisi terbuka. Hal ini akan berdampak terhadap kekuatan ball valve dan butterfly valve. Tekanan yang besar atau melebihi spesifikasi akan mempengaruhi mekanisme kerja dan kekuatan material. Pengaruh tekanan ini menjadi sangat penting dalam ball valve dan butterfly valve karena tekanan fluida dengan temperatur, pada  kondisi tertentu bisa di luar batas spesifikasi khususnya pada ball valve Sanitary SS316 Mounting Pad 3 inci dan butterfly valve Sanitary SS 304 3 inci. Metode yang digunakan adalah Computational Fluid Dynamics dengan bantuan Software Flow Simulasi Solidwork 2014.Kata Kunci: Ball and Butterfly Valve, Solidwork, Flow Simulasi, CFD, Tekanan, Temperatur, Kecepatan aliran. ABSTRACTValves are mechanical devices that regulate fluid flow or pressure. Its function can close or open the flow, control the flow rate, divert flow, prevent backflow, control pressure, or reduce pressure. The problem commonly encountered is that the valve closure is not perfect due to the impurities that prevent the cover from closing completely. The simplest handling is to clean the holder from the dirts earlier and do lubrication. This study aims to explain the description of the flow simulation on ball valve and butterfly valve. This study also explain the comparison of pressure, temperature and velocity of water distribution in two types of valve heads. Fluid pressure under closed conditions is different from opening conditions. This will affect the strength of the ball valve and butterfly valve as a valve. Pressure that is large or exceeds specifications will affect the working mechanism and material strength. The effect of this pressure becomes very important in the ball valve and butterfly valve because of  fluid pressure with temperature under certain conditions it can be out of the specification limits, especially in Sanitary SS316 Mounting Pad 3-inch ball valve and SS 304 3 inch Sanitary butterfly valve. This method was used in research is Computational Fluid Dynamics by utilizing of Flow Simulation Solidwork 2014 Software.Keywords: Ball Valve, Butterfly Valve, Solidwork 2014, Flow Simulation, CFD, Pressure, Temperature, Velocity

The Relationship

Considering the influence of the cutter head plane on manufacturing of spiral bevel gear, the method of 3D model for spiral bevel gear is built based on Program Pro/E. The relationship between the geometric parameters (such as addendum circle, dedendum circle and base circle) and the basic parameters (such as modulus and the number of teeth) of spiral bevel gear is established by using the inner program. The parametric solid model of spiral bevel gear can be obtained automatically by rotation, sweep, blend, and pattern after inputting the basic parameters. This method is significant to improve the accuracy of design and manufacturing of spiral bevel gear.
