Minimal needed resistive forces data for different types of wheels with uniform rectilinear motion on various floors.

These data are the minimal resistive forces for different types of wheel in uniform rectilinear motion on a various flloors. 44 different wheels were tested, varying diameter (80mm, 100mm, 160mm and 200mm), tread (solid rubber, elastic-tyre, thermoplastic rubber, synthetic rubber, injected polyurethane, casted polyurethane and polyamide) and bearing (sleeve bearing, cone ball bearing and precision ball bearing). 5 differents floors were tested: a flat, smooth and horizontal steel plate and 4 resilient floor coverings (3 PVC multilayer floor coverings and 1 monolayer rubber floor covering). These results were obtained at steady state (where acceleration is zero for a constant velocity was 2,5km/h) using an original motorised test bench. Forces were measured with a six-axis force sensor. The tests were carried out, for each wheel and flooring for 5different loads: (13kg, 24kg, 37kg, 49kg and 62 kg). Average forces were then calculated from 3 round-trips. Combining these results with a mechanical model of a cart, permits to modelize the minimal pushing force to move it.
