Optimize landing gear designs from the early development stage onwards
As systems become more complex, functional system analysis is not sufficient anymore. Engineers need deeper physical insight in how systems behave in order to secure the system function and performance. LMS offers a full suite of solutions for aircraft landing gear development and verification.
Simulation driven design of the landing gear from concept to final design
LMS Landing Gear System Simulation solutions help design engineers select and optimize the ideal landing gear concept. Landing gear designs can be analyzed in depth on different levels. Configuration alternatives can effectively be evaluated and optimized. As such, development risks of a new technologies and concepts are anticipated and reduced through the upstream validation of technical choices
- Analyze landing gear structure on loads, stress, movement, durability,… during different conditions (e.g. drop test)
- Analyze retraction, lowering, steering, braking and landing gear interaction with control systems
- Evaluate the landing gear to design requirements
- Optimize weight and durability
- Virtual testing and optimization

Shimmy performance optimization
Landing gear shimmy is a complex phenomenon impacting the performance and safety of aircraft. Its root cause may be traced to a large number of variables, impacting both nose and main landing gear and may result in structural damage or even collapse. LMS engineering services are uniquely qualified to help tackle difficult design issues associated with mitigating shimmy related problems.
LMS engineers leverage simulation, test and combined simulation/test technologies and methods to deliver the physical understanding required to assess and mitigate problems as they arise throughout the design cycle.
A complete portfolio of test-based engineering solutions
As landing gears become larger and more flexible, the impact of vibrations on the aircraft becomes increasingly important. The LMS Ground vibration testing solution covers the process from pre-test structural dynamics simulation, to ground vibration testing (GVT), to the use of GVT results for calibrating structural dynamics models. It is recognized by specialists around the world as a key factor to accelerate verification.
During the landing gear drop test, the LMS test solutions for data acquisition and data analysis are very adequate to acquire and post-process different kind of data: going from force data, movement, speed, acceleration, pressure, stress, …
