A software LMS of Siemens for the structural analysis of the aeroplane To350 XWB of Airbus

The software of LMS, a business of Siemens, has played an important paper in the process of structural analysis of the To350-900, increasing the use of software of simulation with regard to other projects of Airbus. Airbus has created some common surroundings of structural analysis based in LMS Samtech CaeSam, one of the solutions of software of computer-aided engineering (FALL) of Siemens. For the structural development and the certification of the To350-900, LMS CaeSam provided the base for the implementation of methods harmonised of Airbus to more than 2.000 engineers of calculation of structures in more than 50 providers of all the world. LMS CaeSam Provides an only frame that integrates all the processes of Airbus, methods, tools, libraries of data, in replacement of more than 400 tools.

The To350-900, that forms part of the family To350 XWB, is the first aeroplane Airbus developed with the common surroundings of the company known like ISAMI (Improvement of the Structural Analysis By means of the Multidisciplinary Integration). The surroundings ISAMI guarantees the coherence in the structural analysis and the process of certification of the To350. ISAMI Of Airbus bases in the frame LMS CaeSam, that is part of the portfolio of solutions of simulation of LMS Samtech.

The structure LMS CaeSam has helped to Airbus to face his three main challenges in the structural analysis: the harmonisation, automation and implementation. It manages and it automates the processes of engineering for the calculation of the margin of hygiene, providing substantial profits in the time and cost in all the cycle of design. The structure allows the integration of processes and the harmonisation of the tools of dimensionado, taking advantage of the know-how of the company. Besides, LMS CaeSam adapts to help to the aerospace manufacturers to manage the flows of work of structural analysis that result of the increasing chain of global supply.

Thanks to the success of the platform LMS CaeSam with ISAMI, his use has extended to the dimensioning detailed of the structure and certification for the To350-1000 and the To320 neo. Besides, Airbus – jointly with the segment of business of Siemens LMS – has developed a new tool to help to estimate the weight of the aircraft to the start of the process of development. Also based in LMS CaeSam, Airbus uses Presto (predimensionamiento of structures of compound material) for the preliminary dimensioning of the aircraft. The use of Presto in the To350-1000 already has showed a significant saving of time with regard to the previous method.
