Approach for Quantitative Express of Tire’s Foot Print
With special design and manufacture instruments, foot print of used truck tires under different combinations of vehicle load was studied in this paper. The load factor is studied in terms of wheel load and tire inflation pressure. Based on the experimental data, approach for quantitative expression of foot print is also researched. Thus, the behavior of tire-pavement contact can be quantitatively expressed The area of the tire’s footprint should be calculated with different equations varying with the kinds of pavement, and critical change point of the tire’s footprint shape should be decided with load factor varying with the kinds of pavements.
