For a truck, a unisteel radial tire incorporates a single radial ply and a multiple belt system, whilst a bias ply tire has six to eight diagonally oriented plies and no belt system. The advantage of the radial tire is a relatively low internal friction which helps to minimize operating temperatures and rolling resistance.

Jan 15, 2024 · The tire studied in this paper is a radial tire used for heavy-duty vehicles, and it can be seen from its material distribution diagram that different areas are composed of different types of rubber materials, and there are as many as ten kinds, so if all areas are taken into consideration and the material parameters of each area are used as ...

May 15, 2019 · To feature 10–13 t axial load and off-road properties, a heavy load radial tire is designed with a larger section ratio (corresponding to 0.98 for heavy load radial tire) than those of truck, passenger, or car tires (0.8, 0.5, and 0.3, respectively, as shown in Fig. 1). With respect to kinematic modeling and vibration analysis of heavy load ...

May 15, 2022 · The radial tire carcass is composed of composite materials, such as steel wire and rubber. The steel wire is along the radial direction of the tire, whose circumferential tensile stiffness is relatively large. For a frequency range of 400 Hz, the modal vibration mode of a GL073 radial tire is in-plane bending of the carcass.

Jul 1, 2021 · Using the identified tire model parameters from Table 1, the in-plane tangential and radial flexible deformation of a rolling tire could be predicted by the improved tire flexible ring model. The flexible deformation of the tire under different vertical forces with a rotational speed of 80 km/h and the inflation pressure of 2.8 bar are shown in ...

Dec 1, 2021 · The radial acceleration of the tires through the estimated tire dimensionless numbers is shown in Fig. 12. The solid line represents the tire radial acceleration measured by the intelligent tire, and the dotted line represents the radial acceleration based on the flexible ring tire model with the estimated tire dimensionless numbers.

Jan 1, 2011 · To study the rolling properties of a radial tire, an accurate 3D 195/60R14 tire model is established. The modal includes the geometric nonlinearity due to large deformation, material nonlinearity, the anisotropy of rubber-cord composites, the nonlinear boundary conditions from tire-rim contact and tire-pavement contact.

Feb 1, 2024 · The partial vibration frequency of rotating radial tire will be split into two traveling wave frequencies under the influence of Coriolis force and centrifugal force [9, 10, 23]. So that how to accurately and succinctly describe the Coriolis force and centrifugal force for exploring the numerical relationship between the rotating angular speed ...

Jan 1, 2020 · The belt cord of a radial tire arranged along the circumference makes the circumferential stiffness of the tire larger than that of a bias tire. Similar to the vibration of a ring, the natural frequency corresponding to the breathing mode mainly depends on the circumferential stiffness, so it is greater for a radial tire.

Jul 1, 2002 · Moreover, a tire shoulder is also a dangerous region in which the delamination failure on the interface between the shoulder elastomer and the body ply can occur. For a radial truck tire, the tensile force in the body around a tire bead is very important to the tire performance [3]. One of the main purposes of this paper is to evaluate the
