7.7.2.3 Additional moment of inertia

7.7.2.4 Angle of tilt

Symbol Description

add

Additional moment of inertia due to wheels, axes, etc.

• Has an impact on the dynamic torque!

• Value can be entered directly or calculated using the inertial calculator.

Symbol Description

β Angle of tilt (gradient)

• The value can be entered in degrees or as a percentage.

• The max. angle of tilt as a first approximation is: arctan(μ

)

(static friction between the wheel and road surface).

• The angle of tilt of the travel path must be considered when determining the travelling re-

sistance. For a tilted travel path (β≠0), the specific travelling resistance must be recalculated

by means of the "Travelling resistance" calculator and the values for the wheel diameter and

the angle of tilt.
