This work presents a convenient and non-contact acoustic sensing approach for measuring ground vibration. This approach, which uses an instantaneous dynamic tire pressure sensor (DTPS), possesses the capability to replace the accelerometer or directional microphone currently being used for inspecting pavement conditions. By measuring dynamic pressure changes inside the tire, ground vibration ca...

in this study, a simulation of tire–soil interaction model was considered with special view to two-dimensional (2-d) fem model of carcass. coefficients of mechanical behavior of silty-loam soil were accurately measured to obtain an effective simulation. the results of simulation which was implemented in matlab7, showed that the radial-ply tire had greater tractive efficiency than bias tire at t...

─ In a tire pressure monitoring system in which a pressure censor and a transmit antenna are contained in a tire, electromagnetic simulations of radiations from carcass embedded tires are requested. However, it is difficult to accurately determine these shielding effects. In this study, methods for performing accurate electromagnetic simulation by adopting the MoM scheme are determined. In the ...

Today safety of the human life is major concern. Nowadays about 75% of the casualties has been observed due to the accidents during transport of the vehicle. These are especially due to the flaw in the tire pressure. Tire break avoiding is very important for safe driving in superhighway. Wireless Tire Pressure Monitoring System (TPMS) is used to detect whether one or more of the vehicle’s tire ...

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...

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...

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) ...

Plus-sizing, or the fitting of larger diameter rims and lower profile tires to vehicles, continues to be a significant commercial force in the tire marketplace. When offering plus-size fitments to customers, many sellers simply offer “what fits” on a given vehicle. However, the various choices made by the seller, such as wheel width, wheel offset, inflation pressure, and so on, have the potenti...

recently, mixtures of clay-tire chips are used as construction material in civil engineering projects. with respect to the tending for using these materials, it is necessary to know their mechanical behavior. thereby, a number of undrained monotonic triaxial tests are carried out on the specimens of pure clay and clay-tire chip mixtures. mixed specimens prepared by mixing pure clay with 10%, 20...

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...
