- 摘要：The rolling and sliding state of the tread rubber material within contact patch
was very important to the handling stability and safety of the vehicle. In this
paper, first, the absolute coordinate system was introduced into the digital
image correlation method, which improved the ability of the traditional digital
image correlation method to solve the large deformation of polymer material
surface. Second, a new calculation method of rolling friction coefficient based
on the brush model was proposed. Third, a non-contact full-field rolling
dynamics experimental device was developed to study the effects of carbon
black components, rotational speed and vertical load on the rolling mechanical
characteristics of tread rubber material. On this basis, the rolling mechanical
characteristics of tread rubber material with different formulations were
obtained by analyzing the distribution properties of global strain rate, full-field
longitudinal speed and full-field longitudinal acceleration and the variation
laws of transverse/longitudinal strain rate, trajectory of marked points, stressstrain
hysteresis curve and rolling friction coefficient. Finally, the influence
mechanism of carbon black composition on rolling mechanical properties of
tread rubber material was revealed.
