A method of producing artificial micro-profiles which imitate real unsurfaced roads


, : A method of producing artificial micro-profiles which imitate real unsurfaced roads. Selskostopanska Tehnika 18(6): 44-54

A method is described of producing a continuous, universally-applicable random micro-profile, the dynamic impact of which on a moving wheeled agricultural machine should be equivalent to the real micro-profile. Low-frequency components of the artificial micro-profile exercised little influence and were eliminated.
