Calculating the stress-strain state of the rubber-cord shell of an elasto-screw propeller

The development of off-road all-terrain vehicles to be used in the Russian Polar region with a harsh climate and lack of roads is very important. The stress-strain state of an air-supported propeller installed on the all-terrain vehicle with a rotary-screw chassis using a flexible shell is studied. The initial profile of a rubber-cord shell and its cross-sectional shape are calculated depending on the contact pressure of the ground. This study makes it possible to simulate the behavior of the propeller shell contacting with snow, liquid and hydromorphic grounds, which can help to avoid expensive field experiments when designing all-terrain vehicles.
