K&C Rig Workshop

Use of Kinematics and Compliance Measurement for Simulation of Heavy Truck Vehicle Dynamics
Monday May 4, 2009

In conjunction with the 2009 SAE Heavy Truck Handling, Dynamics and Control Symposium, Michelin Americas Research Company (MARC) will hold a half-day seminar on the afternoon of May 4 on kinematics and compliance testing, results and use of data for heavy truck vehicle dynamics analysis.

The seminar topics include:

• Vehicle dynamics simulation approach: multi-body vs. functional suspension models,
• The science (and art) of completing kinematics and compliance measurements on heavy trucks, including steering characterization, vertical and roll kinematics, longitudinal and lateral compliance, and chassis flexibility,
• Guided visit of the Michelin Americas Research Company heavy truck kinematics and compliance test rig,
• Review of characteristics for typical heavy-truck suspensions, including several case studies,
• Trucksim model development from:
  • Kinematics and compliance data,
  • Tire force and moment characteristics,
  • Braking system,
  • Electronic aids: ABS and ESC simulation, and
  • Additional parameters (sprung / unsprung mass, Cg position, inertia, etc.)
• Validation of simulation results, including steady-state understeer, random steer, brake in curve and avoidance / rollover maneuvers.
