Aircraft Landing Gear Simulation using Abaqus/Explicit

SIMULIA's picture

A mechanical system, such as aircraft landing gear, can have a large number of parts that interact in a complex nonlinear fashion. The challenge of simulating such a sys-tem lies not only in capturing the correct physical behavior but in using efficient analysis techniques. Different levels of modeling abstraction may be appropriate for different stages of the design process. Initial sizing and kinematics can be studied with a partially rigid representation, while final designs are more often analyzed with fully meshed flexible geometry.
The use of Abaqus/CAE and Abaqus/Explicit to develop a process for predicting landing gear performance is out-lined in this Technology Brief. By combining the automa-tion and customization capabilities of Abaqus/CAE, the robustness of Abaqus/Explicit, and Unified Finite Element Analysis (UFEA) concepts, we show how the Abaqus product suite can be used to efficiently analyze mechani-cal systems.
