Abstract An intranet-based tool for integrating an enterprise-wide simulation-based design and manufacturing environment for mechanical systems is presented. The tool is invoked as a Java applet from a web page. Users can browse global product model data from the applet and retrieve and store product data between the global product data server (called the Design Data Server) and their local workspaces. Network connections are based on the CORBA standard. This environment enables the achievement of concurrent engineering goals. It gives the members of an enterprise-wide product development team a convenient, uniform interface to the global product data from different platforms. It allows their various simulation and modeling tools on the different platforms to interoperate through the Design Data Server.

Hardware Platforms

Within a shipyard, designers have their own design objectives and moreover apply different software on heterogeneous hardware platforms; nevertheless requested collabtive operation still remains in the comple design circumstance. The paper presents a data hub model to sovle this problem and improve effectiveness and efficiency for ship design. The model is simulation-driven and consists of two main parts, including data management and integrated simulation environment. The data management processes the simulation-based design data storage, access and transformation. The integrated simulation environment bridges the gap among the multidisciplinary domain including CAD geometry, CAE, virtual navigation, kinematics and dynamics simulation. In addition, an application is developed to evaluate the validity of data hub model for ship design.

Abstract This paper presents a two-level product modeling method that supports Simulation-Based Design (SBD) of mechanical systems, primarily ground vehicles and heavy equipment, for preliminary and detailed design. A Computer-Aided Design (CAD) model combined with engineering parameters and mathematical equations that describe physical behavior of the mechanical system constitute its product model for SBD. For preliminary design, improvement of system performance, including dynamics and human factors, is the primary focus. A CAD model with reasonably accurate physical parameters, such as mass properties, is defined as the base definition of the product model. A parametric study can be conducted to search for design alternatives using dimension parameters created in the parameterized CAD model. Component designs are the primary focus in the detailed design stage. A detailed product model is evolved from that of the preliminary design, by refining geometric representation of mechanical components in CAD and expanding product assembly into parts and sub-assemblies for further engineering analysis. In the detailed design stage, a systematic design trade-off method is usually needed for design improvement. In both design stages, CAD and Computer-Aided Engineering (CAE) mappings that tie dimension parameters in the CAD model and physical parameters of simulation models facilitate the parametric study and design trade-off by quickly generating simulation models to simulate performance of the modified design. A High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) is employed to illustrate and demonstrate the modeling method.
