“…Field measurement of tire contact stress began in 1959 [17]. At present, various types of sensors have been developed for tire force measurement [18], [19], [20], [21]. De Beer et al [5], Hernandez et al [22], and Luo et al [23] measured tire force by different types of measurement systems.…”

Tire force is one of the important factors influencing mechanical response of pavement structure. Tire force cannot be measured yet under a high-speed rolling condition because of complicated spatial distribution. To provide a representative form of the tire force to pavement mechanical analysis, this paper established an interaction model of rolling tire and rigid surface. To compare with the equivalent single-wheel load for pavement design, an 11.00R20 tire was chosen as a prototype. Steady-state transport analysis was conducted using a mixed Eulerian /Lagrangian approach, in which a rigid body rotation is described in the Eulerian manner and deformation is described in the Lagrangian manner. The influencing mechanism of tire operation parameters on tire force was explored by analyzing the simulation results of tire contact stress under several working conditions. Results demonstrated that three directions of contact stresses, namely, the vertical, longitudinal, and transversal stresses, exist simultaneously under the steady-state rolling condition. Amplitudes of longitudinal and transversal stresses are at the same magnitude with vertical stress, which should not be neglected during the mechanical response analysis of the pavement structure. Tire rolling state, axle load, tire pressure, and pavement friction coefficient could significantly influence the spatial distribution of contact stress, while speed is insignificant to contact stress. The results provide a reference for the establishment of tire force in pavement model, which is the basis of mechanical behaviours and early failure mechanism for pavement surface.

“…Nonetheless, due to Internet coverage, the range of technology-based services and applications is almost in¯nite. Accordingly, there are under development smart tyres [Zhang et al (2013)], smart wheelchairs [Huang et al (2017)], wearable devices, which measure biological functions and are interconnected with intelligent vehicles [Sun et al (2017)], or smart watches designed for measurement of biological data and can enable the user to avoid possible medical emergencies [Do et al (2016)]. Studies examining technological development mainly focus on \hard" data (such as a country's index of internet coverage) while disregarding human aspects [Rojas-M endez et al (2017)].…”

Past decades’ rapid development of technological innovations can ease individual’s everyday lives, but they can also convey a sense of frustration. The aim of the present study was to investigate attitudes toward technologies that are expected to become widespread in the near future. The Technology Readiness Index was administered to a sample of Hungarian respondents to measure the capacity to adopt technologies. The results add significant novelties about the specific patterns related to perceptions of considerably different future technologies, emphasizing the unique role of optimism. Derivations are further specified by demographic characteristics, future directions and practical implications are also discussed.

“…Adverse road conditions and faulty tires are often responsible for traffic accidents [1]. Therefore, sensors embedded in tires capable of monitoring real-time road conditions and tire health would be a step ahead in terms of automation and safety measures [4,5]. Additionally, in the development phase of a new tire, various conditions for tire testing need to be monitored and validated.…”

In this article, we report the development of a flexible, 3D printable piezoresistive pressure sensor capable of measuring force and detecting the location of the force. The multilayer sensor comprises of an ionic liquid-based piezoresistive intermediate layer in between carbon nanotube (CNT)-based stretchable electrodes. A sensor containing an array of different sensing units was embedded on the inner liner surface of a 3D printed tire to provide with force information at different points of contact between the tire and road. Four scaled tires, as well as wheels, were 3D printed using a flexible and a rigid material, respectively, which were later assembled with a 3D-printed chassis. Only one tire was equipped with a sensor and the chassis was driven through a motorized linear stage at different speeds and load conditions to evaluate the sensor performance. The sensor was fabricated via molding and screen printing processes using a commercially available 3D-printable photopolymer as 3D printing is our target manufacturing technique to fabricate the entire tire assembly with the sensor. Results show that the proposed sensors, inserted in the 3D printed tire assembly, could detect forces, as well as their locations, properly.
