The Airbus A350 Aircraft’s Structural Analysis with Siemens LMS

Using Siemens’ LMS Samtech Caesam computer-aided engineering (CAE) software, Airbus has created a stress analysis environment to replace their 400 in-house tools. The analysis environment, dubbed ISAMI (Improved Structural Analysis through Multidisciplinary Integration), is used by over 50 worldwide suppliers and 2,000 stress engineers for the certification and design of Airbus’ A350-900 plane.

The ISAMI was able to integrate processes, tools, methods and libraries used by Airbus and Samtech’s simulation solution suites to perform the same function. This ensures that the structural analysis and certification of Airbus designs are consistent.

The A350-900 is the first of the A350 XWB family to be designed using the ISAMI environment. With the new environment the automation, deployment and harmonization of the structural analysis could be completed faster.

ISAMI can automate the calculations of design safety margins allowing Airbus to save design cycle time. Furthermore, custom Airbus sizing and processing tools can be integrated into ISAMI to share company knowledge and procedures with all that use the program. Finally, ISAMI can calculate and manage structural analysis simulations to keep the manufacturer on top of various projects.

Airbus can also optimize aircraft sizes using a tool they produced with Siemens to predict the weight of an aircraft during early development and LMS Caesam PRESTO (Pre-sizing of Structures for Trade-Offs).

The success of ISAMI has led Airbus to expand its use to the A350-1000 and A320neo aircrafts as well.
