“…Since a two-dimensional pavement model was used for the statics analysis, the applied load in the modeling process needs to be converted from the surface load (tire ground pressure) to line load. The relationship between the tire ground pressure and axle load can be expressed by Equation (9) [ 39 , 40 ].

A new type of plastic and basalt fiber composite (PB) modifier, which is composed of waste plastic and basalt fiber using a specific process, was used for bus lanes to address severe high-temperature deformation diseases due to the heavy loads of buses. The dense gradations of asphalt mixture with a nominal maximum aggregate size of 13.2 mm (AC-13) and 19 mm (AC-20) were selected to fabricate asphalt mixtures. The impact of the modifier PB on the high-temperature rutting resistance, low-temperature crack resistance, and water damage resistance was investigated experimentally. The experimental results showed that adding the modifier PB could enhance the rutting resistance and water damage resistance of asphalt mixtures significantly while maintaining the low-temperature crack resistance. Then, PB-modified asphalt mixtures of AC-13 and AC-20 were employed into a typical pavement structure of a bus lane in Yangzhou city, China, and three types of designed pavement structures were proposed. On this basis, statics analyses of all of the designed structures were performed using the finite element method. The statics analyses revealed that, compared with the standard axle load, the actual over-loaded axle made the pavement structure of the bus lane suffer a 30% higher stress and vertical deformation, leading to accelerated rutting damage on the bus lanes. The addition of the modifier PB could make the pavement structure stronger and compensate for the negative effect caused by the heavy axle load. These findings can be used as a reference for the pavement design of urban bus lanes.

“…Moving on the marshy and soft terrain, the possibility of transferring forces and moments at the contact of the tire with the ground is used with reduced tire pressure. Lowering the pressure increases the contact surface area and reduces unit pressure on the substrate [12]. The farm tractor moves both on uneven terrain, overcoming various obstacles, which affects the tires and suspension [9,13], and on paved roads with reduced tire pressure.…”

Experimental research on agricultural tractor movement, acquisition and archiving of kinematic features is an important issue in the analysis of braking and acceleration processes. The obtained traffic parameters depend on the environmental conditions, condition and type of pavement, load, tire pressure and the area of tire-pavement cooperation. The acceleration factor, and in particular the braking process, is determined by the coefficient of friction enabling the assessment of forces and moments acting at the tire-road interface. The kinematic features known as a result of measurements can be used to assess the extent of road safety. The article describes experimental research aimed at understanding the kinematic features of agricultural tractor movement without a trailer on a homogeneous asphalt surface at three pressures in drive tires.

“…In the case of passenger vehicles, simulations of the behaviour of the structure are carried out at the design stage of the individual components, and then polygon tests in extreme weather conditions and crash tests are carried out. In addition, simulations of the behaviour of individual systems are performed, such as simulation of vehicle wheels and suspension when overcoming various obstacles that may actually appear on the road or computer tests of displacements of individual body parts during a traffic accident and operation (carried out at their design phase) [1][2][3][4].…”

In the article design of a self-propelled vehicle for inspecting ventilation ducts and ceiling structures in buildings equipped with omni wheels was presented. Such vehicles are used in places that are hard to reach for people. The vehicle was designed using the vehicle control system – ARDUINO. For this system dedicated program was written, which is used to operate it. The vehicle is remotely controlled by radio waves. Its range is about 100 meters and the power supply is a 12 V battery. The vehicle operator has joysticks (controllers) modelled on those used in game controllers that are used for precise vehicle control. The vehicle is equipped with cameras that allow to view the image in real time. The omni wheels have also been tested for strength by the finite element method (FEM). Carried out FEM analysis as part of the work allowed to determine the strength of omni wheels on the acting forces during vehicle movement.
