THE HANDLING AND STABILITY OF MOTOR VEHICLES. PART 6 MEASUREMENT OF STEADY CORNERING BEHAVIOR USING A TETHERED TESTING TECHNIQUE

IN TETHERED TESTING, THE TEST-VEHICLE (BEING INVESTIGATED) IS ATTACHED BY MEANS OF A BOOM TO A TETHERING VEHICLE WHICH PULLS THE TEST-VEHICLE ALONG AT A CONSTANT LOW SPEED. THE TETHER CONSTRAINS THE TEST VEHICLE ONLY IN A HORIZONTAL PLANE; THE TEST VEHICLE IS FREE TO MOVE VERTICALLY AND TO ROLL, PITCH, AND YAW. TETHERED TESTING PROVIDES A USEFUL METHOD OF INVESTIGATING AND QUANTIFYING STEADY STATE AND SOME PSEUDO STEADY STATE HANDLING CHARACTERISTICS OF MOTOR VEHICLES. THE PRINCIPAL DISADVANTAGES OF THE TECHNIQUE ARE ITS UNSUITABILITY FOR INVESTIGATING OVERSTEERING, AND ITS INABILITY TO MEASURE SPEED-DEPENDENT EFFECTS. A SERIES OF EVALUATION TESTS ARE DESCRIBED AND THE RESULTS ARE PRESENTED PRINCIPALLY IN THE FORM OF PLOTS OF STATIC MARGIN VERSUS LATERAL ACCELERATION. THE VEHICLE CONDITIONS INVESTIGATED WERE TIRE PRESSURE, SWAY BARS, AND THE TRANSMISSION OF BRAKING AND DRIVING TORQUES. THE EXISTING CONCEPT OF STATIC MARGIN IS A READILY USEFUL METHOD OF EXPRESSING STEADY-STATE HANDLING CHARACTERISTICS. /AUTHOR/
