Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.

The effect of laser surface texturing to inhibit stick-slip phenomenon in sliding contact

Advances in Mechanical Engineering, 2019
Stick-slip phenomenon in some mechanical structures, especially in machine tools, should be eliminated or inhibited, otherwise the vibration will occur and the position error will inevitably be obtained. In this study, different kinds of surface textures

Some Aspects of the Analysis of Stick-Slip Vibrations With an Application to Drill Strings

Volume 1C: 16th Biennial Conference on Mechanical Vibration and Noise, 1997
Abstract This paper deals with a systematic procedure to calculate periodic solutions of dynamic systems experiencing dry friction. In this first attempt we limit ourselves to 1 and 2 dof autonomous models where a smooth approximation of the discontinuous friction force is applied.
