Haul truck tire dynamics due to tire condition

The Simulation of Truck Tire Rolling Noise

The road transportation sector places a severe burden on large parts of the population in the form of road traffic noise. A main contributor to this is the rolling noise generated by the tires of trucks and other heavy vehicles. Advanced simulation tools are not only needed for a better physical understanding of rolling noise generation, but also for the design of quieter tires and road surface...

Rubber friction and tire dynamics.

We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model wi...

Tire-pavement Coupling Dynamic Simulation under Tire High-speed-rolling Condition

The coupling effect between tire and pavement is an intensively researched subject to analyse the dynamic interaction of the vehicle-pavement system. By considering the 11.00 R20 tire and expressway asphalt pavement, ABAQUS software was employed in this study to establish an improved model for simulating the coupling effect, in which the tire rubber was taken as a neoHookean material and the pa...

A Tire Side Slip Model with Flexible Tire Carcass and the Identification of Tire Structural Parameters

i’ire behaviour plays a very important role in vehicle dynamic studies. Because of the complexity of tire structure, some tire models use so many assumptions they cannot represent tire behaviour well, while others are so complicated they are di@icult to use in engineering applications. This study presents an analytical tire side slip modeI with flexible tire carcass which is very helpful for un...
