THE OBJECTIVE OF THE STUDY DESCRIBED IN THE PAPER IS TO DETERMINE THE EXTENT TO WHICH PEDESTRIAN PROTECTION CAN BE PROVIDED BY PRACTICAL CAR DESIGN MEASURES. THE PROJECT EXAMINES THE EFFECTS OF VEHICLE IMPACTS UPON THE SIX-YEAR-OLD CHILD AND 50TH PERCENTILE MALE ADULT. EVALUATION OF VEHICLE DESIGNS PRIMARILY INVOLVES THE USE OF THE CALSPAN CVS COMPUTER PROGRAM FOR PEDESTRIAN IMPACT SIMULATION. COMPUTER MODELS OF DUMMIES HAVE BEEN DEVELOPED WITH THE SIMULATION METHOD BEING VALIDATED AGAINST PRACTICAL TESTING. MODIFICATIONS HAVE BEEN CARRIED OUT ON THE OGLE ADULT DUMMY TO IMPROVE THE PERFORMANCE OF THE LEG IN LATERAL IMPACTS. ADDUCTION OF THE HIP JOINT HAS BEEN INCREASED AND THE KNEES HAVE BEEN GIVEN LATERAL COMPLIANCE TOGETHER WITH SUITABLE TORQUE CHARACTERISTICS. THE RESULTS FROM TESTS AND SIMULATION SHOW GOOD CORRELATION AND GIVE CONFIDENCE IN THE MODELLING TECHNIQUE. THE INFLUENCE OF VARIOUS FRONT-END CHANGES HAVE BEEN STUDIED WITH COMPUTER SIMULATION USING A SIMPLIFIED VEHICLE REPRESENTATION.(A) FOR THE COVERING ABSTRACT OF THE CONFERENCE SEE IRRD 802816.
