Nacrtak The motion resistance ratio, gross traction ratio and net traction ratio of a wheel cable skidder were determined and mathematical models derived for three tire inflation pressure values with or without tire chains on forest road in mountainous conditions. The motion resistance ratio increases with the increase of tire inflation pressure. On the contrary, the gross traction ratio increa...

A pneumatic soft robot can be made autonomous by carrying a liquid chemical fuel. In the existing design, to transmit fuel, pressure of fuel tank must exceed that actuator. Consequently, sufficiently stiff, which hardens robot. Herein, inspired pit membranes in trees, pump is developed, consisting nanoporous membrane between and actuator, coated with catalyst on side The migrates across and, me...

Non-pneumatic tires (NPTs) have been widely used for their advantages of no run-flat, need air maintenance, and unique stiffness characteristics. This study focuses on the design a spoke Fibonacci spiral non-pneumatic tire (FS-NPT) based its properties three-dimensional stiffness. Finite element (FE) models, parametric studies, designs experiments (DOEs), sensitivity analyses are conducted to e...

Trucking fleets and owners of commercial vehicles utilize both new and retread tires on their vehicles in the United States. Retread tires are used primarily for the cost advantage they provide over a similar new tire. Despite the advantages that retreaded tires may bring, public perception is that retread tires are less safe than new tires as evidenced by the amount of tire debris frequently f...

Abstract The airless tires are developed to overcome a disadvantage of pneumatic tire which lost maneuverability caused flattening and blasting. finite element analysis (FEA) is an effective method for development have complex construction. material properties describe mechanical behavior each component very important yield accurate result. high order constitutive model usually obtains the accu...

Introduction . The most efficient machine for compacting road building materials in the construction of transport facilities, a roller with promising pneumatic tire that can effectively use vibration, is considered. Materials and methods results studies characterizing parameters imprint contact working body supporting surface, which significantly affect efficiency technological operation materi...

This paper introduces a technique that relates the coefficients of the Magic Formula tire model to the physical properties of the tire. For this purpose, the tire model is developed by ABAQUS commercial software. The output of this model for the lateral tire force is validated by available tire information and then used to identify the tire force properties. The Magic Formula coefficients are o...

While a new tire may have excellent resistance to crack initiation and propagation between the steel belts, an aged tire of the exact same construction can exhibit dramatically reduced crack growth resistance, which in some cases may contribute to tire failure. This article will review the research that has gone into quantifying the rate of oxidation the steel belt rubber oxidizes in different ...
