Road surface irregularity is known to effect vehicle NVH responses. When modeling vehicle NVH, it is desirable to have high-resolution measurements of the road surface to use as road input. For typical NVH modal tire models, the road surface sampling rate will not be an issue because several points on the tire patch (center line) are used to determine the road surface irregularity. The single p...

Tire characteristics and behavior are of great importance in vehicle dynamics since the forces transmitted in the tire-road contact are the main contributors to global vehicle performance. Several research groups have focused on the study and modeling of tires. Some of the most important factors that need to be known are tread characteristics and pressure distribution in the tire-ground contact...

This paper discusses the development of a deformable terrain database to be used in a co-simulation environment with a multibody dynamics vehicle model. The implementation of the model includes a general tire-terrain traction model which is modular to allow for any type of tire model that supports the Standard Tire Interface[1] to operate on the terrain. Rather than utilizing empirical terramec...

Waste tires have excellent mechanical performance and have been used as reinforcing material in geotechnical engineering; however, their interface properties are poorly understood. To further our knowledge, this paper examines the pull-out characteristics of waste tire strips in a compacted sand, together with uniaxial and biaxial geogrids also tested under the same conditions. The analysis of ...

Non-thermal irreversible electroporation (N-TIRE) has shown promise as an ablative therapy for a variety of soft-tissue neoplasms. Here we describe the therapeutic planning aspects and first clinical application of N-TIRE for the treatment of an inoperable, spontaneous malignant intracranial glioma in a canine patient. The N-TIRE ablation was performed safely, effectively reduced the tumor volu...

In this paper, we focus on the frequent glitches of general family cars. Based on the Neural Network theory and combining with the Micro-chip processor technology, we design an expert system-‘‘Integrated Cars Repairing Tools” (ICRT) and the size of the proposed ICRT is quite small and achieves the following attractive functions: (1) Portable Electric-jack, (2) Electric Tire-pressure-meter, (3) ...

Mixing of filler particles with elastomers is one the most important steps in tire manufacturing process. Precipitated Silica (Si), as a filler, shows enhanced properties compared carbon black when incorporated an elastomer such low rolling resistance, high wet grip performance, and wear resistance. According to standard rubber mixing process, fragmentation during must yield breakage size that ...

in this paper, multi-objective uniform-diversity genetic algorithm (muga) with a diversity preserving mechanism called the ε-elimination algorithm is used for pareto optimization of 5-degree of freedom vehicle vibration model considering the five conflicting functions simultaneously. the important conflicting objective functions that have been considered in this work are, namely, vertical accel...
