Remote Handling Refurbishment Process for the European IFMIF Target Assembly: Concept Design, Simulation and Validation in Virtual Environment

In the heterogeneous environment, fast and real-time information exchange is the requirements of rapid developing and information integrated for mechanical products. Meanwhile, it is also the basis and guarantee of virtual prototyping. This paper analyzes the process of mechanical product design, particularly starts from the concept design stage of virtual product to achieve information sharing and building information models, put forward a software network environment based on objects and STEP standards for integrated information model and the basic PVPIIM framework, application protocol's development, leaf characteristics of the definition and expressions. Furthermore, we proposed a distributed virtual environment in the virtual prototyping development and make it support the whole pump virtual product development process on basis of PVPIIM for an integrated virtual environment, where we use virtual reality modeling language VRML to describe the 3D geometric shape, material, texture, color and virtual design background of pump parts.

With globalization, more and more companies are becoming multisited. Efficient and timely collaboration and communication among the development team members become critical for product success. This paper proposes a web-based virtual environment for mobile phone customization, named VMPDS (Virtual Mobile Phone Design Space). The features of this system include the combination of web technology and VR (Virtual Reality) technology, the ability to deal with and extend the product model database, adequate interaction for three-dimensional product model customization, and usefulness for the examination and evaluation of product concept design. The system is implemented by using standard open technologies to assure accessibility and platform independence.

This paper presents a software architecture that enables VRMDS (Virtual Reality Mechanism Design Studio) to simulate multi-body dynamics of computer-aided design (CAD) assemblies. VRMDS is a recently developed virtual environment dedicated to the conceptual design of mechanisms and machines. It allows users to build spatial or planar mechanisms through intuitive operations. In this paper, we develop Python’s parsing modules that import CAD assembly models in either XML or MDL format files into VRMDS and visualize them through the use of WRL or OSG geometry files. CAD assembly models consist of parts as well as kinematic constraints among them. These parts and constraints can be translated into links and kinematic joints of mechanisms and machines. The dynamics simulation for the assembly is achieved by MATLAB SimMechanics solver that communicates with VRMDS through a dedicated Pymat interface and M-script files. Finally, two case studies are provided to demonstrate the feasibility and validity of using assembly models in this virtual reality system for mechanism design. The high fidelity of the SimMechanics dynamics solver makes the simulation justified scientifically. The result is a highly integrated virtual reality design environment that is dedicated to both the concept design and virtual prototyping of machines.

Set Up

The ITER (International Thermonuclear Experimental Reactor) is an international collaborative project, and its object is aiming at demonstrating the scientific and technological feasibility of fusion energy for peaceful purposes. In the ITER, the four important engineering challenges are the first wall of the blank model, the remote handling (RH), the heating of the plasma, and the superconducting technology. The RH control system is very complexity, and the total number of the control nodes is 15378, which consists of the control nodes in the Tokamak equipment, the hot cell equipment and the control room equipment. Only the number of the control nodes of the transfer cask system (TCS) is up to 2580. The TCS is one sub system of ITER RH system, which provides the means for the remote transfer of (clean/activated/contaminated) in-vessel components and remote handling equipment between hot cell facility and vacuum vessel through dedicated galleries and lift in the ITER buildings. Due to the experimental facility with a very long timeline, the control software on the ITER is better suited using an open source solution as compared to a commercial solution. According to market share and proven record, command control and data acquisition and communication (CODAC) group chooses the EPICS (Experimental Physics and Industrial Control System) as the preferred solution. China takes part in the ITER, and wishes to grasp the RH technology, which is one of the four key technologies related to the future fusion reactors for electric power generation. According to the CODAC system configuration with EPICS component, the concept control architecture of the TCS is presented in this paper. The control system consists of the file network, the interlock network, the safety network, real-time network, RH control network and visual supervising network etc. Then, the paper analyses each part corresponding requirement function. As a result, a development service platform concept is set up. Finally, the experiment system of the leg of the TCS has been constructed.

In this study a methodology of computer aided conceptual design in product development based on ergonomics was put forward. When products concerned with people are designed, ergonomics should be taken into account. The digital human model was used to decide the layout of design scheme. Ergonomics features were extracted in workplace analysis. With the aid of software Pro/Engineer, the whole human and machine virtual environment were built. A case of the modeling and size specification of the excavator cab for different drivers was given as the example to show the whole design process. The results shows that the development of ergonomics, computer aided concept design and anthropometry can help the designers to improve product development.
