LMS, the engineering innovation company, today announced the
introduction of a dedicated simulation solution for landing gear
systems based on LMS Virtual.Lab Motion. The new solution allows
development teams to build detailed aircraft landing gear models,
reliably simulate their real-life performance, quickly assess
multiple design alternatives and optimize aircraft designs before
prototype building. LMS Virtual.Lab Landing Gear has been developed
in close cooperation with several aircraft and landing gear
manufacturers to cover the specific engineering challenges in
developing landing gear systems.
LMS Virtual.Lab Landing Gear supports development teams in gaining
a detailed insight in the dynamic behavior of the landing gear, and
its overall performance in terms of reliability, stability and
safety. The integrated solution supports the analysis of the
behavior of the landing gear in all regular maneuvers. It also
assesses the response of new system designs to extreme and failure
load cases, for which physical tests are either too dangerous or
too costly to perform.
LMS Virtual.Lab Landing Gear includes a dedicated user interface
which is fully customized to the specific modeling and simulation
process for landing gear engineering. This allows users to build
their design from pre-defined and fully parameterized landing gear
templates or to create their own landing gear configuration
template. To assure a realistic representation of the landing gear,
the simulation models include tires, wheels, brakes, telescopic
oleo damper struts and linkages to brace and retract the system.
The models incorporate aerodynamic loads and information about
retraction, deployment, take-off, landing and ground maneuvers.
Based on the model parameters, LMS Virtual.Lab automatically
assembles the complete landing gear model, applies the ground load
cases, runs the simulation and performs standardized post
processing of the results. This integrated process eliminates
extensive modeling efforts, removes potential modeling errors and
supports the quick assessment of design alternatives.
The new Landing Gear solution is based on LMS Virtual.Lab Motion,
offering advanced multi-body simulation capabilities to assess
dynamic system behavior. LMS Virtual.Lab Landing Gear therefore
takes the flexibility of components and the operation of control
systems into account to accurately calculate loads on components
and the complete landing gear under a wide range of operating
conditions. For example, landing gear retraction and extension can
be simulated to size the actuators and hydraulic valves that drive
these maneuvers. Takeoff, landing, taxiing, symmetric and
asymmetric braking and other ground maneuvers can all be accurately
simulated to validate the correct functioning and the safety limits
of new landing gear designs.
Dedicated post-processing features help engineers to easily
identify and solve problems in the landing gear design. Users can
review dynamic responses, including all system loads, accelerations
and positions. They can detect collisions based on detailed CAD
models, analyze motion envelopes and force vector animations.
“LMS Virtual.Lab Landing Gear addresses the key requirements
of landing gear development teams to assess the overall performance
of a new design or a set of derivatives in the shortest possible
time,” commented Willy Bakkers, Vice-President and General
Manager of the LMS CAE Division. “The new LMS Virtual.Lab
solution ensures that aircraft engineers can optimize their design
before building prototypes and maximizes their return from the
available test resources.”
