Case Study: TREMEC reduces gearbox block out and manufacturing cost with Hexagon

TREMEC - Customer Case Study

TREMEC, a manufacturer of high-performance automotive gearboxes, faced a challenge with its gear-shifting control mechanism. The kinematic chain of components was susceptible to unexpected displacements due to tolerance variations, which could lead to a "total block out" and prevent the driver from changing gears. To improve reliability and performance, TREMEC partnered with Hexagon and employed its Adams and ODYSSEE CAE software to analyze and optimize the design.

Hexagon's solution used a virtual prototype in Adams to run design of experiments (DOE) studies, identifying how different tolerance ranges affected the mechanism. This data was then fed into ODYSSEE CAE to rapidly predict optimal new tolerance ranges. By implementing these sensitivity results, Hexagon helped TREMEC increase some tolerances by up to 100% and decrease others by 40%. This optimization reduced instances of partial block out by 8%, significantly improved the mechanism's functional response, and lowered overall manufacturing costs.
