France : SIEMENS LMS software selected by Airbus A350 XWB

February 17, 2014

Software from LMS, a Siemens business, has performed an important role in the A350-900 structural analysis process, resulting in the software s expanded use in other Airbus projects.

Airbus formed a common stress analysis environment based on LMS Samtech Caesam, one of Siemens computer-aided engineering (CAE) software solutions.

LMS Caesam for the A350-900 structural development and certification provided the foundation for deploying Airbus harmonised methods to over 2000 stress engineers at more than 50 worldwide suppliers.

LMS Caesam offers a single framework that combines all Airbus processes, methods, tools and data libraries, replacing over 400 tools.

The A350-900, part of the A350 XWB family, is the first Airbus aircraft developed using the company s common environment known as ISAMI (Improved Structural Analysis through Multidisciplinary Integration).

The ISAMI environment make sure consistency in the A350 structural analysis and certification process and is based on the LMS Caesam framework, which is part of the LMS Samtech suite of simulation solutions. The LMS Caesam framework has assisted Airbus tackle its 3 main challenges on structure analysis: harmonisation; automation and deployment.

It directs and automates engineering processes for safety margin calculation, giving a substantial time-cost benefit over the full design cycle. The framework also permits the integration of harmonised sizing processes and tools, capitalising on company know-how.

Moreover, LMS Caesam is tailored to assist aerospace manufacturers manage structural analysis work streams that result from the growing global supply chain.

Consequently of the LMS Caesam platform s success with ISAMI, its use has now been extended to perform detailed structural sizing and certification for the A350-1000 and the A320neo.

Furthermore, Airbus together with Siemens LMS business segment has developed a new tool to help estimate aircraft weight early in the development process.

PRESTO (Pre-sizing of Structures for Trade-Offs) is utilized by Airbus for preliminary aircraft sizing. The use of PRESTO on the A350-1000 has already shown a noteworthy time saving over the previous method.
