Aircraft landing gear is an essential system that allows any aircraft to start from the gate, taxi to the runway, and take off and land safely.
Nose and main landing gear systems include powerful actuators, structural struts and beams, complex wheels and brake systems, all subjected to high load, stresses and harsh environmental conditions.
The landing gear mechanism requires complex multibody dynamics and high-load simulation on the structural parts and the wheels, tyres and brake components. Hexagon Manufacturing Intelligence supports these needs with a range of computer-aided engineering (CAE) software, including multibody dynamics and coupled simulation tools.
Hexagon’s production software solutions can also simulate the production process, calculating the right amount of material to be machined and ensuring tool paths are optimised, while our CAM software will generate and communicate optimised trajectories to machining centres.
When manufacturing a landing gear strut, beam, wheel or brake, these circular and cylindric parts need to be inspected both inside and out during production to ensure that the materials have been made correctly. Our on-machine probing solutions can support measurement during production, while our data analytics tools can compile in-line metrology data to anticipate manufacturing defects early and make corrections within the production process. Hexagon’s automated non-contact metrology tools also enable quick process monitoring and dimensional inspection of landing gear components and assemblies near the production floor.
Analysing and accurately predicting how aircraft systems like landing gear will fatigue during service is a key safety concern for aerospace designers.
With such a range of potential operating conditions, the ability to simulate and optimise landing gear systems for different scenarios is crucial for safety and performance.
