With Rev 11, LMS expands world-class LMS Test.Lab Transfer Path Analysis portfolio fatigue analysis and composite simulation

Best-on-the-market solutions to understand the root cause of noise and vibration.

LMS International offers the most complete portfolio of transfer path analysis (TPA) solutions available. Built on more than 30 years of continuous research and development work, LMS TPA methods are the problem-solvers of choice for noise and vibration engineers in the world’s leading manufacturing industries – including practically every major automotive OEM.

“What the market appreciates is our hands on and comprehensive approach to transfer path analysis. We listen to our customers and help them implement the right techniques for the variety of noise and vibration problems they encounter. A top example in our TPA portfolio is our patented LMS Test.Lab OPAX technique. Using its wider frequency range for increased accuracy, engineers can quickly identify the root causes of noise and vibration issues faster than ever before. Plus the depth of our portfolio means that there is a TPA solution to tackle all kind of issues from every possible angle,” explained Bruno Massa, Vice-President, Test Division at LMS International.

In complicated structures with various sub-assemblies, such as cars, aircraft or ships, vibro-acoustic phenomena at a certain location may be caused by a remote vibration source. For example, the energy from a car engine is transmitted into the passenger cavity by a number of different routes: from the engine mounts, the exhaust system connection points and even indirectly via the drive shafts and the wheel suspension. These complex noise and vibration issues can be thoroughly examined using enhanced TPA techniques to help engineers detect root causes early in the design cycle. LMS Test.Lab provides a highly efficient solution to identify unwanted noise and vibration, trace it back to its origin, and quickly evaluate design improvements.

“As a systematic approach for any test-based engineering process, TPA is a valuable time-saving method that helps engineers set the right brand-critical noise and vibration performance targets on both the full system and component levels. With an optimized product development cycle, engineers actually ‘pre-design’ the ideal components to avert undesirable noise and vibration. On the other hand, TPA remains a popular method for troubleshooting existing vibro-acoustic issues, and is rapidly spreading from its core application area in automotive to other manufacturing industries, such as white goods, office equipment and even aviation and shipbuilding,” added Bruno Massa.

A pioneer of transfer path analysis, LMS commercialized the first TPA product in the early 1990s under the LMS CADA-X platform. Today, this know-how is baked into the market-leading LMS Test.Lab solution.
