Responsibilities

Deliverables :*Development, and validation, of Vehicle Dynamics functionality as it relates to Chassis quality/warranty of Client vehicles OR development, and validation, of ride, steering, handling, and tire performance to meet functional objectives of Client vehicles..
*The overall objective is to minimize vehicle/suspension sensitivity to variation in forces induced by road surfaces, assembly build variation, vehicular architecture, and/or wear.
*Responsible for quality testing activities throughout all Program development phases; from up-front target setting and design definition, through in-vehicle testing on prototype properties, and then pre-production (pilot) properties.
*Ensure that critical components have appropriate targets/specifications to minimize sensitivity to brake rotor wear (judder), tire/wheel imbalance, vehicle lead/drift/pull, steering wander, torque steer, and vehicle shake (ride). This will be accomplished through a combination of simulation, objective testing, and subjective evaluation methods
*Responsible for in-vehicle development of the critical components to meet the vehicle’s overall ride, steering, handling, and tire performance objectives.
*This development work takes place predominantly at the Chelsea Proving Grounds in Michigan, with travel required to other test locations as both weather, and test surface conditions dictate (Significant travel occurs during the winter months, with trips lasting 2-3 weeks at a time. Travel is mostly domestic within North America, but can also be international, and is approximately 20% of the time)
*Requires specialized driving skills for subjective ride, steering, routine handling and limit handling evaluations.
*Responsible for the leadership of all CAE/virtual analysis activity associated with steering/suspension hard-point development; steering/suspension component stiffness /damping specification; and ride/handling
performance optimization for all variants of a vehicle architecture, including formulation of design recommendations.
*Analysis/optimization of suspension/steering sub-system kinematics and compliance.
*Analytical assessments of steady state/transient handling behavior; and calculation of associated component loads for various Handling events (Emergency handling/fish-hook, Trailer Tow SAE J2807, Slowly Increasing Steer, Step Steer, Off-Road events for Trail Rating.) Simulation of ride events and associated characterization of performance (Primary Ride (Low frequency events), Secondary Ride (High frequency events), Impact harshness , Vehicle pitch under braking, Vehicle head-toss , Shimmy and Wander and Brake Judder.)
Development/validation/ownership of all associated vehicle/sub-system simulation models (multi-body/ADAMS, parametric/CARSIM, VICarRealtime, NASTRAN/flex-body.)
