Laboratory experimental study of tire tractive performance on soft soil: Towing mode, traction mode, and multi-pass effect

Tire tractive performance, soil behavior under the traffic, and multi-pass effect are among key topics in research of vehicle off-road dynamics. As an extension study (He et al., 2019a), this paper documents testing a tire moving on soft traction mode or towing mode, with single pass multiple passes, presents results mainly from aspects performance parameters, these parameters. The influence inflation pressure, initial compaction, normal load, number passes test data has been analyzed; for some tests, analysis was completed statistically. A phenomenon, different any phenomenon recorded available existing literature, discovered related to ripple formation failure. can be considered groundwork dynamics development controllers vehicles soil.
