Numerical research of selected features of the non-pneumatic tire

In this article non-pneumatic tires (NPT) subject area was taken. This term (NPT) must be understood as the specific structure, which provide appropriate quasi-static and dynamic characteristics (to compare with pneumatic tire) without necessity to maintain a compressed gas or liquid under a certain pressure. Prepared numerical model of non-pneumatic tire represent the solution available on the commercial market. The validation of the model was carried out the own experimental research results. During the numerical research of the non-pneumatic tire model, simulations of the normal force loading with different values were carried out, the shapes of the NPT contact areas were recorded on the rigid ground.
