Case Study: Energy Absorption Systems achieves faster redesign cycles and an optimized clevis linkage with ANSYS Workbench

Integrating Simulation into Product Development Streamlines the Design Process

Energy Absorption Systems, Inc., a world leader in crash cushions and impact attenuators, needed to redesign the clevis linkage on its TMA-180 truck-mounted attenuator after switching to a different hydraulic cylinder supplier. The change in cylinder geometry and loading threatened delays, so the company turned to ANSYS, using ANSYS Workbench integrated with Autodesk Inventor, to quickly develop a reliable redesign and reduce time to market.

ANSYS Workbench’s bi-directional CAD associativity let engineers extract geometry, run simulations, and update designs without rebuilding loads or meshes, enabling rapid what-if iterations to evaluate materials and reduced part thickness. By using ANSYS, Energy Absorption Systems shaved days off the redesign cycle, brought the modified attenuator to market faster, and produced an improved, more thoroughly vetted clevis linkage.
