Finite element modeling of static tire enveloping characteristics
To investigate static tire enveloping characteristics, a three dimensional (3-D) finite element model is proposed. The vertical stiffness of the tire is studied on a flat surface with and without cleat. Tire rubber materials and cord layers are represented independently using -rebar- elements...
A study of the vehicle structure crashworthiness in dolly and curb-trip rollover tests
Rollover crashes can be the most dangerous vehicular crashes among all crash types which have a higher fatality rate than other kinds of crashes. The orthogonal design was adopted to evaluate structure parameters how to affect the vehicle rollover crashworthiness in dolly and curb-trip tests. It is...
Analysis of performance ratings for tires
This study analyzed two sets of performance ratings for light-duty-vehicle tires. The aim was to ascertain whether some of the ratings in either set convey redundant information. The first set included the Uniform Tire Quality Grade (UTQG) ratings for 2,734 tires, published by the U.S. National...
Experimental analysis of tyre-enveloping characteristics at low speed
In this study, experiments are conducted to investigate tyre-enveloping characteristics. Four different types of tyres are tested. Parameters such as different tyre inflation pressures, vertical loads and types of obstacles (cleats) are considered. In addition to vertical stiffnesses of all tyres,...
Pavement surface specification for road load measurement
This report proposes a framework for specifying coast - down test surfaces that will produce relevant, reproducible road load measurements. The proposed specification includes grade, roughness, megatexture, and mac rotexture. Specification using standard scales in use by the pavement monitoring...
