Today, Computer Aided Engineering (CAE) has become an essential part in the development of Thermal-Acoustical Protective Shields (TAPS). As presented three years ago, such a theoretical approach has been able to reduce the development cycle of TAPS while simultaneously reducing costs. Using the approach as previously presented gave us an opportunity to learn more and upgrade the approach with more modules. These modules are focused not only on obtaining better accuracy but also adding information about processes and function of the TAPS. Besides those parameters we are now able to look up-front into the visual appearance of the product using simulation techniques. This paper will describe this updated CAE approach, with a main focus on the new added techniques and modules. This paper will also describe how the results of the approach are used in the development of new TAPS and how we verify the theoretical results by the means of experimental techniques.

Today, Computer Aided Engineering (CAE) is a feature that becomes more and more essential in the development of Thermal-Acoustical Protective Shields (TAPS). The development cycle of TAPS needs to be reduced while simultaneously reducing costs. The performance, functionality and visual appearance need to be improved as well. This paper will describe our general CAE approach, which is based on the use of different CAD systems and Finite Element Analysis (FEA). We will describe how we use the results of our approach in the development of new TAPS. Because this approach is based on the knowledge of the parameters that exist and how they influence a TAPS function, we will first discuss the most important of these parameters. Here we split our discussion into ‘What is a TAPS, ‘What are the main steps of making a TAPS - Designing, prototype’, and ‘How a TAPS works in an engine’. We will then explain the different FEA utilization's.
