Challenge

Problem set 2 -week 3 challenge : Anti-Characteristics

Load Transfer lbs 328.29
Front Wheel Rate lb/in 259.92
Rear Wheel Rate lb/in 336.96
Front End Deflection Under Load in 0.63
Rear End Deflection Under Load in 0.49
Pitch Angle deg 0.65
Pitch Gradient deg/g 1.30 pitch angle * g / throttle acceleration
Front Anti-Lift Angle deg 3.45 Assume IRS since anti's are calculated relative to wheel center. Torques reacted by subframe, chassis body
Rear Anti-Squat Angle deg 6.04 Assume IRS since anti's are calculated relative to wheel center. Torques reacted by subframe, chassis body
Front Swing Arm Angle, 100% Anti-Lift deg 9.84 arctan(cg height/wheelbase)
Rear Swing Arm Angle, 100% Anti-Squat deg 9.84 arctan(cg height/wheelbase)
Front Anti-Lift Percent % 0.00 0% for RWD
Rear Anti-Lift Percent % 61.42 (theta/theta_ideal)*drive ratio*100
Actual Swing Arm Angle, e/d deg 20.63
Rear Anti Squat % % 209.63 (theta/theta_ideal)*drive ratio*100
Front Anti-Lift % % 0.00 0% for RWD
Front End Delfection, Compensated in 0.65 rebound
Rear End Deflection, Compensated in -0.53 compression
Pitch Angle, Compensated deg 0.07 Theoretically should be zero.
