Chassis development advanced

Altair ProductDesign’s correlated simulation technology is applied here to a single-lane-change vehicle-dynamics event.

Altair ProductDesign and Summitech Engineering recently announced the joint development of a method to create correlated passenger-car multibody dynamics (MBD) models without requiring OEM information.

"We are delighted with the methodology this partnership has produced," said Dr. Hong Su, Engineering Director, Summitech. "Using a combination of Summitech facilities, Altair MotionSolve software, and the experiences of both organizations, we have successfully created correlated vehicle dynamics models of two very different vehicles. These models will be central to the optimal design of future vehicle components."

Summitech partnered with Altair ProductDesign for its broad expertise in chassis development, including subjective vehicle evaluations, objective lab and proving ground measurement, target setting, MBD model creation and correlation, and CAE-driven design and vehicle development. The goal of this initial engagement was to establish a repeatable process, without requiring OEM and supplier data and resources, that allows a deeper understanding of benchmark vehicles and determination of baseline performances to employ simulation-driven design methods.

Tony Norton, Land Vehicles Practice Leader at Altair ProductDesign, said: "The model-building process starts with key benchmark data and judicious population of half-car models. After a comparison with kinematics and compliance test results, full vehicle models are assembled. The process has provided great correlation with the proving grounds data measured by our team."

In the ongoing design and engineering crusade that is vehicle lightweighting, grams count. In some cases, tenths of a gram count. Regardless of how fuel price has moderated in the U.S. in recent years, the importance of global platforms and global markets means the drive to create more mass-efficient vehicle structures, subassemblies and components continues unabated.
Cab doors that open 180° thanks to a new hinge design are one innovative feature on the recently unveiled 2017 Titan King Cab model.
Still riding on a separate hydroformed-steel ladder frame (itself redesigned and CAE-optimized for greater strength and lower mass), the new eight-passenger SUV sheds up to 300 lb (136 kg) compared with the incumbent model. The mass reduction enabled Ford engineers to move to a powertrain format using only the 3.5-L turbocharged V6 with auto stop-start and 10R80 10-speed automatic.
