Michigan Baja Racing (MBR) is a collegiate race team in the North American Baja SAE intercollegiate
competition. The team designs, builds, and tests a new single-seater off-road race car from scratch
every year to compete against hundreds of other teams across the United States. The competition
consists of a design presentation and other static events. The main dynamic events are acceleration,
maneuverability, hill climb*, suspension and traction (S&T), and a four-hour endurance race.
Crimson Racing has a history spanning nearly two decades with Formula SAE. However,
the past five years have easily been the most successful in team history. Why? A concerted focus on understanding and justifying everything on the car without over complicating it.
There are many tools and programs that can be used to achieve this goal on various systems,
but for structural components in the suspension system, Altair HyperWorks™ has been
the most prolific. By using the Altair MotionSolve™ program in HyperWorks, Crimson Racing
can evaluate the expected suspension component loads under any given driving scenario
and adjust as needed.
In order to reach its goals the team used various tools from Altair‘s HyperWorks software suite. In particular HyperMesh and HyperView for pre- and post-processing as well as OptiStruct and MotionView to optimize the system‘s weight and dynamic behavior. In a first step MotionView was used to obtain the loads on the suspension system and to verify the kinematics of the system. Then HyperMesh was employed to mesh the components and to apply forces and constraints to simulate the most severe stress condition such as braking while cornering, applying vertical, longitudinal and lateral loads.
For the final designed robot, HyperWorks was used for structural analysis to understand whether or
not the robot meets the requirements. The evaluation was performed for the impact force received
when launching a rocket, the impact when landing from the sky and the impact vibration from
the road surface during running. MotionSolve in HyperWorks was extremely useful for practical
industrial education that is linked to CAD design.
