The damping efficiency of a helicopter landing gear is represented by its load-stroke curve. Maximizing damping efficiency, through a more rectangular shape of the load/stroke curve, should ensure sufficiently high and steady damping irrespective of actual landing gear compression.

To realize this, engineers set up an Optimus-driven simulation process that automatically manages the co-simulation between LMS Imagine.Lab AMESim and LMS Virtual.Lab. Optimus orchestrated 1D and 3D simulations toward an optimum landing gear configuration balancing multiple design objectives

Increased simulation throughput

Optimus easily captures and successfully automates Imagine.Lab AMESim & Virtual.Lab simulations, delivering a repeatable simulation process. Combining Optimus with parallel computing capabilities increases simulation throughput, minimizing the time needed to execute a carefully planned DOE campaign.

Fast multi-objective optimization

Using Optimus’ Response Surface Modeling (RSM), an auto-validated RSM was fitted through the DOE response points. Multi-objective optimization performed directly on that RSM is significantly faster because it eliminates the need to run a long series of coupled 1D and 3D simulations during the optimization process.

Smart strategies deliver benchmark performance in record time

Total elapsed time is minimized thanks to a smart combination of DOE, RSM and optimization strategies – delivering benchmark landing gear performance 10 times faster compared to conventional simulation methods.
