"Impact Behavior Modeling of Motorcycle Front Wheel-Tire assembly," International Journal of Automotive Technology, Vol. 10, #3, pp. 329-339. Description: Results of a 2^(5-1) fractional factorial experiment measuring Y = crush radius on front wheel of a motorcycle tire. Factors and levels are (where D is confounded with SMPG interaction): S = Impact Speed (meters/second) (3, 6) M = Impact Mass (kg) (51.18, 101.33) P = Tire Pressure (kPa) (148, 252) G = Striker Contact Geometry (radius= 0.03, 0.10) D = Impact offset Distance (m) (height= 0, 0.108) Variables/Coumns Treatment 7-8 Impact speed 15-16 /* -1=3, +1=6 */ Impact Mass 23-24 /* -1=51.18, +1=101.33 */ Tire Pressure 31-32 /* -1=148, +1=252 */ Striker Contact Geometry 39-40 /* -1=0.03, +1=0.10 */ Impact Offset Distance 47-48 /* -1=0, +1=0.108 */ crush radius 52-56 run order 63-64
