Software claims breakthrough system-level CAE

The latest release of LMS Virtual.Lab offers an integrated environment to engineer key performance attributes such as noise and vibration, durability, ride and handling.

The latest release of LMS Virtual.Lab offers an integrated environment to engineer key performance attributes such as noise and vibration, durability, ride and handling.

The product is also the first ever to allow users to combine the reliability and accuracy of test results with the speed and flexibility of virtual simulations to leverage the best of both technologies.

LMS Virtual.Lab Rev 2 delivers new process-oriented simulation solutions for component- and system-level durability engineering, scalable and accurate motion simulation, engine acoustics prediction, and for system-level noise and vibration prediction.

"Typically, manufacturers have many years of experience and confidence in testing their products.

But today's global competition, and the availability of computer generated designs, argue for faster prediction of product performance directly from those designs", says Jan Leuridan, LMS Chief Technical Officer.

"Our mission remains to lead the industry in integrating CAD and CAE, addressing multiple key performance attributes in one single environment, and combining the test and virtual worlds to produce better, faster and more cost efficient virtual simulations.

LMS Virtual.Lab Rev 2 does exactly that: it focuses on making the complex process of virtual simulation much easier and more effective".

LMS Virtual.Lab Acoustics Rev 2 offers an integrated solution to optimise the acoustic performance of a new engine design.

Convenient modelling and acoustic meshing capabilities combined with powerful and reliable solver technology reduce the full simulation process from days to just a couple of hours.

The parametric analysis capabilities of LMS Virtual.Lab deliver the capability to automatically assess multiple engine design variations on their acoustic performance.

Tailored visualisation tools such as multi-rpm and multi-frequency colour map diagrams offer "on the spot" engineering specific insights into the acoustic behaviour of the design.

Within Rev 2, LMS Virtual.Lab Noise and Vibration was further completed with new capabilities for noise and vibration system assembly and contribution analysis.

LMS Virtual.Lab Noise and Vibration is now the only commercial available solution in the market to perform noise and vibration analyses on the level of a full vehicle or aircraft.

It is able to identify the most dominant modes or sources of vibration problems, and allows to analyse the critical paths along which vibrations propagate throughout the car or the aircraft.

These insights provide reliable information on how to improve designs to reduce excessive noise and vibration levels before committing to expensive prototype testing.

The LMS Virtual.Lab Motion Rev 2 application implements a complete solution for multibody dynamic analysis.

It includes fast and easy fully parametric 3D modelling and mechanism authoring, making it possible to develop models quickly and very close to real life.

The transparent use of flexible components combined with high speed and very precise solvers are key to realistically simulate flexible mechanisms, and to consequently take the correct engineering decisions.

The integration of LMS Virtual.Lab Motion with other key attributes such as acoustics, vibration and durability in one engineering environment now makes it possible to put into practice system-level and multi-attribute functional performance engineering.

LMS Virtual.Lab Durability Rev 2 now fully integrates the durability engineering simulation process from components to complete assemblies such as a car suspension, car body, or aircraft landing gear.

It easily combines component FE (finite element) models and dynamic component loads, and indicates the fatigue hot spots.

It supports quick parametric re-runs of the fatigue analysis to assess multiple design alternatives.

LMS Virtual.Lab Durability automates the durability validation of seam welds, by automatically detecting seam weld locations and types, so eliminating the need to manually check these on the virtual model.

The ultimate goal for advanced durability engineers is to optimise sub-assemblies as a whole - and not just at the component level.

Through the tight integration of LMS Virtual.Lab Motion and Durability, multibody simulations, flexible body analyses and durability-specific tire models can be combined to form an unparalleled loads prediction environment - the "virtual test rig" and "digital test track".

LMS Virtual.Lab Rev 2 also includes new capabilities for component Structural Analysis.

This product module brings the Dassault Systemes generative structural analysis capability in LMS Virtual.Lab, where it complements process-centric configurations for motion and durability.

The integrated capability provides functionality for static and dynamic analysis, including specific capabilities for the modelling of flexible components in mechanism analysis.

Component structural analysis will work directly on the CAD geometry of components, this all within LMS Virtual.Lab thereby significantly raising overall simulation efficiency.

LMS Virtual.Lab is based on CAA V5 (Component Application Architecture), the open middleware for PLM from Dassault Systemes.
