CAE Approach for Thermal-Acoustical Protective Shields 2001-01-0684

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. Here we will describe how we obtain the information about thermal shielding, acoustical behavior, obtaining the blanket shape, the forming process, and how we can optimize process and function. We will compare all these stages in general with the current (practical) approach and show the advantages of our new approach. We will look at experimental methods to explain how we can verify the calculated results.
