Lead author in a parametric study the effect of vehicle speed and tire grade on tire friction in locked-wheel braking. Vehicular speed loss before skid mark deposition was quantified as a function of a remote speed at start of skid. Co-investigator in a study of the effect of head restraint placement and seat back stiffness on the kinematic and kinetic response of anthropomorphic test dummies in low speed rear end impacts. Co-investigator in a parametric study on the effect of impact pulse parameters on the kinematic response of anthropomorphic test dummies in low speed rear end impacts. Performed data analysis for a study of the kinematic and kinetic response of anthropomorphic test dummies in low speed rear end impacts. Neck loads were measured with load cells and calculated from head accelerations and head restraint loading data. The responses of two different dummies was compared with that of human volunteers. Lead author of a study of the performance of pickup truck bumpers in low speed impacts. Front and rear bumpers of 5 different pickup trucks were tested, using both barrier and vehicle impacts. Co-investigator in a study to validate a method of using bumper component tests to predict full vehicle behaviour in low-speed collisions. Developed a mathematical model to correlating full vehicle dynamics to individual component dynamics. The model was validated with 1624 tests. Performed data analysis for a study of tire friction under wet and dry conditions. These 540 tests showed the difference between three grades of tires, and documented the delay between brake application and the start of skidding. Performed data analysis for a study of occupant kinematics in low speed rear end collisions. Sophisticated statistical analysis determined the set of the most influential of 31 independent factors for each of 27 dependent kinematic parameters.
