A new product design process: Combining the system model and VRTC

Abstract

A new product design process, the virtual reality transferred by correlation (VRTC) is presented to lower the cost and shorten the product development process. The workflow is based on the comprehensive analysis of the problem to build a simulation-driven design process, which is used for both decisions of making the design parameters and minimizing the need for tests. By combining the VRTC with a system model, the designers can make a quick assessment for the design for the whole system and shorten the product's time for market with an improved quality. A vibro-acoustic analysis on a loudspeaker diaphragm is presented to show the effectiveness of the workflow. By measuring the mode shapes and sound pressure, the relation between vibrations of diaphragm and sound generated can be found, and then we can redesign the speaker's structure to generate desired sound quality. © 2013 Springer Science+Business Media New York.
