Life Reduction Factor
Note: CV (Rzeppa) joints eliminate speed variation inherent in U-joints (Hooke). Max operating angle is typically 47° for outer joints, 22-25° for inner (plunging) joints. SAE J901 CV joint standards.
Reference
Additional Angle = arctan(Bump_travel / Shaft_length)
Max Angle = Static + Additional
Hooke Speed Var = (1 − cos(angle)) / cos(angle) × 100%
Plunge = Length × (1 − cos(angle))
Life Factor ≈ (22° / Max_angle)³ [reference life at 22°]
