System concept development with virtual prototyping

Abstract

Virtual prototyping with 3D drawing programs provides a means of rapidly developing system concepts and analyzing them for form, fit, logistics, human factors integration, and general feasibility analysis.The resulting models can be studied, viewed from different angles, and even "entered" by multidisciplinary design teams working in an integrated product team environment. The authors were involved in two separate system configuration developments that benefited tirn an initial virtual prototyping approach. The first example presents the development of an electric gun concept for a ballistic missile defense application. The gun model was based on current technology developments and experiment results, and was constructed to answer the question "what configuration can be assembled in the near term that would be air transportable?" The second example illustrates the development of a small waste remediation facility, and was constructed to provide a configuration baseline fbr study. The process of converting each project's miscellaneous available technical data into a correct high-fidelity model is presented, and key technical insights provided by the virtual prototype are also presented.

Lean Approach to Production Planning for Large Solar Photovoltaic Installations

“…Virtual prototyping is commonly accepted as the design or construction of computer models permitting realistic graphical simulation [16].Virtual prototyping with 3D modeling applications provides an opportunity to analyze form, fit, logistics, human factors, and feasibility [17]. There has been a wide range of virtual prototyping facilities employed for different construction planning tasks and collaborative purposes [18].…”

Control Parameters Optimization Based on Co-Simulation of a Mechatronic System for an UA-Based Two-Axis Inertially Stabilized Platform

“…The value of VP is rapidly being recognized for a wide range of engineering applications. These applications range from illustrating the potential of a system early in the technology assessment activity or early developmental phase to detailed analysis of mature designs in the advanced engineering phase [10]. ADAMS™ is a successful software for VP analysis [11].…”

Developing rapid prototype-capable applications for industrial mobile robot platforms

“…In order to reduce the verifications time these two steps are nowadays organized with the virtual prototyping concept [1] [2]. This means that the system model is high-fidelity, which is obtained by a substantial time and costs investments.…”
