Space Structures uses ESI Software to Secure the Integrity of Satellite Panels during Launch under ESA Contract

Accurate Vibro-Acoustic Simulation Leads to Higher ROI and Customer Satisfaction

(PresseBox) (Paris, France, )
ESI Group, leading innovator in Virtual Prototyping software and services for manufacturing industries, announces the successful completion by German customer Space Structures of a project for the European Space Agency (ESA). As simulation models are key to ensuring the integrity of vital launch equipment subject to high-intensity acoustic field during launch, accurately modeling acoustic conditions is an important challenge. Space Structures used ESI's vibro-acoustic simulation software VA One to virtually test their designs in various acoustic noise environments. They could qualify the structural stress and strength responses of carbon-fiber composite panels, early in the design stage - improving their return on investment for this project, and increasing the satisfaction of their own customer, the European Space Agency.

One of the main challenges in the aerospace industry is to accurately predict acoustic and vibration responses under rocket launch conditions, as the intense acoustic field experienced during the early launch phase, including liftoff, can cause severe structural damage. Specifically, the integrity of both the spacecraft and protective fairing, along with sensitive ground-based equipment, can be impaired at launch. Most approaches to evaluate launch acoustic conditions use older calculation or empirical methods and rely heavily on trial-and-error testing information from legacy designs. These provide little opportunity for design optimization and such methodology can lead to inaccurate results, conservative assumptions, excess weight, and are likely to neglect frequency-dependent characteristics. In this context, independent engineering firm Space Structures GmbH sought to employ an advanced simulation methodology that would eliminate such limitations.

Specialized in the development of metal and composite structures for space applications, Space Structures was commissioned by the European Space Agency to develop a multi-functional panel for large satellites. Building on their core competences in the development of carbon-fiber composite structures for large spacecraft and years of experience in designing the right equipment for launch environments, Space Structures envisioned a new, cutting-edge methodology that would reduce uncertainties related to the ability of the structures to withstand the launch acoustic environment, and would enable them to address the topic early in their design process. As they laid out this ambitious project, Space Structures decided to extend their simulation capabilities to include the prediction of structural stress and strength responses during acoustic excitation.

With help from ESI teams, Space Structures created a Boundary Element Model (BEM) with more than 250,000 nodes, a landmark achievement unthinkable in the industry just 10 short years ago. Florian Ruess, Managing Director of Space Structures GmbH, comments: "ESI VA One is an outstanding software product. However, the real success is provided in the proactive, flexible, timely and high-quality support of the ESI team from our first contact with the sales team to our contact with technical support."

Today, Space Structures has expanded their business thanks to the simulation tool and now have a customer service department that routinely conducts analytical verification and design optimization of spacecraft structures, including vibro-acoustic simulation. With the assistance of ESI's technical service, Space Structures learned to benefit from the comprehensive functionality of VA One across the full-frequency range. The company realized a high return on investment and saw raised levels of customer satisfaction. In the future, Space Structures intends to continue their use of VA One to improve structural design for all acoustic noise environments For more information about ESI's solution for vibro-acoustics simulation, please visit:
