Wheelchair tire rolling resistance and fatigue.
The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented. An example calculation of rolling resistance for a polyurethane tire is giv...
متن کاملAn Efficient Numerical Scheme for Evaluating the Rolling Resistance of a Pneumatic Tire
The viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with energy saving. The transient dynamic analysis for including the rolling effects of the tire requires long CPU time and the obtained results are ...
متن کاملNumerical Computation of Rolling Resistance Based on the Result of Tire/Road Static Contact Analysis
Among various dissipating mechanisms, the viscoelastic effect of rubber material on creation of rolling resistance is responsible for 10-33% dissipation of supplied power at the tire/road interaction surface. So, evaluating this kind of loss is very essential in any analysis concerned with improving the fuel consumption of vehicles and resultantly energy savage. Hysteretic loss is a fraction of...
متن کاملThe 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...
متن کاملFinite Element Model for Steady-State Rolling Tire Analysis
The paper describes a finite element model for steady state rolling tire analysis. The model, which is improved in comparison to earlier models created by the authors, enables a larger number of analyses to be conducted in less time and with greater accuracy. The descriptions of model structure and model building procedure are given, followed by the algorithm according to which the improvement ...
