Radomes are a key part of antenna systems, which can seriously degrade transmitted and received signals. Modeling and simulation time for complex radomes can extend from days to weeks, and that also includes FSS structures embedded into them.

In the context of NVH vehicle development, a common source of costly design change is where issues are discovered late in a program during vehicle testing or even post launch. Often this occurs where the simulation has met the targets including vehicle level analysis. By considering a population of results rather than the nominal CAE result, a process is demonstrated to develop a more reliable design that will deliver high levels of customer satisfaction and lower levels of late change and warranty costs. In this presentation we will introduce how this can be achieved through the use of MSA and RBDO methods within the framework of Altair’s NVH Director environment.

A radome is a structural enclosure that protects antennas and electronics from harsh weather and environmental factors without degrading electromagnetic signals to the radar. It is designed to have minimal impact on the electrical performance of the antenna and to withstand structural and wind loading performance requirements. They are used across multiple industries, including aerospace, defense, electronics, and telecommunications. Radomes, especially those containing multiple layers and curved FSS elements, are complex and the modeling and simulation of these systems can commonly take days and even weeks to complete. Altair’s streamlined radome simulation solution reduces this time to minutes. This webinar will overview Altair’s radome simulation solution and its application to design a radome system. Who Should Attend? This webinar has been designed to address the needs and challenges of engineering managers, EMC engineers, antenna engineers and designers, RF engineers, and Radio site engineers from military contractors (OEMs and their suppliers), defense governmental organizations (including navy, air force, army), and aerospace companies (OEMs and their suppliers).

Improving the ESL using Complete Vehicle Correlation In the previous webinar, the development of an ESL has been shown based on a complete vehicle simulation. In order to validate this new approach, a comprehensive correlation work has been performed. Using the dynamic distortion in all closure body openings as correlation criteria offer a unique possibility to increase the understanding of the load from both the engine and the wheel suspension. This webinar presents this correlation where a test vehicle is driven on different test tracks both in reality and virtually. Presenter: Jens Weber | CAE Engineer, CEVT

Wireless electronic devices these days often support both Bluetooth and Wi-Fi connectivity. The 2.4 GHz Wi-Fi frequency band is very close to the Bluetooth operating frequency. The co-existence of these two technologies within the same device lead to interference issues. This webinar presents Altair’s EM solution to solve the coexistence and interference issues in smart devices.

ESL Development Based on Simulation - Application example The body stiffness has a major impact on the Squeak & Rattle performance of a car. Since the body structure of electrical/autonomous cars will differ clearly from traditional bodies, an enhanced requirement is needed to limit the distortion in the closure openings. This webinar presents a new approach of defining a requirement based on closure deformations using an equivalent static load (ESL), which considers both the reduction from a complete vehicle to a BIG and from a dynamic load to a static load. In addition, an example is shown how ESL can be used as input for body optimization. Presenter: Viktor Jonsson | CAE Engineer (Consultant), CEVT
