Abstract:

One of the promising ways to achieve high speed and smooth running of rail vehicles during stable movement in straight sections of the track and to improve the characteristics of fitting the vehicles in a curve is the use of independently rotating wheels in their running parts. Such undercarriages are already becoming quite widespread, for example, in urban rail transport vehicles. But independently rotating wheels can rotate in a wheel pair around a common axis with different angular velocities. It follows that during their movement, longitudinal creep forces do not arise, which form the cont

Abstract:

The safety and economic feasibility of railway transport are largely determined by the reliability and efficiency of the wheel-rail pair. At the same time, the intensity of wear of elements and the rate of development of fatigue defects must be such as to ensure economically feasible operation of rolling stock and tracks. Operational reliability and durability of the wheel-rail pair is ensured by a rational balance of wear and wear resistance. Purpose: to analyze various types of operational defects that occur on the rolling surface of the wheel and rail head and to investigate structural chan

Abstract:

One of the most acute problems faced today by Railway Transport Companies is the rapid wear of locomotive wheel borders in the freight transport. Hence, the purpose of this article is to find ways to reduce the forces acting on the wheels of railway vehicles, generally during their movement in small radius turns. For means of simplification has been assumed that the train is moving at uniform speed during a curved path. Analyzing the scheme of action of forces on the pair of wheels, we see that one of the ways to reduce this consumption phenomenon is to reduce the parasitic moment of frictiona

Abstract:

In the article the author notes that the horizontal forces arising in the process of pressing the wheel flanges to the working edge of the rail, under certain conditions can be very significant. These forces, in combination with the wheel unloading, caused by the geometric deviation of the track in the plan and profile, can lead to rolling the wheel of the wheelset onto the rail head and, as a consequence, to the stock derailment. Such pressing of the wheel to the rail head in the straight part of the track can occur when faults in the running gears of the wagons: non-parallelism of the axles

Wheel wear is one of the most critical factors affecting the vehicle performances and maintenance costs of railway vehicles.

Abstract:

Wheeled vehicles can move not only on a solid supporting surface, but also on deformable surfaces (snow, ground, sand, etc.). When a pneumatic wheel with a high internal air pressure rolls over deformable soil, the nature of the wheels’ interaction with the ground is such that the wheel can be considered rigid, since its normal deformation is small. This greatly simplifies the calculations associated with the analysis of the wheeled vehicles’ operation, taking into account the transforming properties of the wheel mover, in particular, the determination of the kinematic and power parameters of

To avoid wheel slippage as the mechanism turns, two omniwheels are installed in front and two regular tires in back, enabling the front wheels to slide freely sideways while the two back wheels continuously contact the ground.

Today, the braking process of uncoupled cars on hump yards with low productivity is carried out manually, using the brake shoe method. This braking method is based on replacing the rolling friction of the wheel on the rails with the sliding friction of the shoe base and another wheel, not equipped with a shoe, on the track. This sliding of the wheel, not equipped with a shoe, on the rails leads to its uneven wear and the creation of a linear section on the rolling surface, known as a one-sided slider. Such a slider significantly reduces the service life of not only the wheels themselves, but a

Abstract:

Abstract The interaction of the wheel and the rail, being the physical basis for the movement of trains, determines not only such important technical and economic indicators of railway transport as the weight of trains and their speed, the reliability and operational life of wheel sets, but also the basis of the foundations of railway operation - the safety of train traffic. Therefore, studies of the problems of interaction of the wheel-rail friction pair are relevant and in demand not only within the framework of a particular wagon or locomotive depot, but also in the country’s railway transp

Abstract:

This paper presents a new type of omnidirectional and holonomic mobile platform with a four-wheel-drive (4WD) mechanism for improving traction of electric wheelchairs on slippery surfaces and enhancing mobility on rough terrain. The 4WD mechanism includes a pair of normal wheels on the back and a pair of omniwheels on the front. The normal wheel in back and the omniwheel in front, on the same side of the drive mechanism, are connected by a power transmission to rotate in unison with a common motor. Omniwheels enable the front of the mechanism to roll freely from side to side. A third motor tur

Abstract:

A direct method for determining the stress intensity factor for wheel pair axes is improved based on the introduction of criteria for evaluating the quality of the finite element grid. The theoretical position is used that the stress intensity factor completely determines the stress state level at points located near the crack tip. Using the finite element method, pictures of the stress-strain state of wheel pair axes with cracks and stress intensity factors calculated through stresses near the crack tip are obtained. It is shown that the stress intensity factor values are the same in the loca

The cut of passenger cars due to wear damage to the rolling surface of the wheelset in 2022 is considered. It is found out that the most typical damage is a shelled tread. An analysis of the methods for restoring the rolling profile of wheels showed that the wheel milling with an end mill can be used as a promising one. To assess the effectiveness of the method, metallographic and tribological studies of wheel samples subjected to turning and milling are compared. According to the study results, it is found that when machining samples of wheel steel by end milling, their wear resistance is 22%

Introduction. The problem of the shortage of energy-efficient restoration technologies makes it a priority to develop new technological equipment for the restoration of the rolling surfaces of railway wheels using highly concentrated energy sources.

Abstract:

Solid-state superionic conductors (SSICs) promise significant improvements over liquid electrolytes for energy storage technologies. The advancement and application of SSICs in battery technologies are currently constrained due to an insufficient comprehension of the mechanisms underlying their ion conduction. Conduction in molecular ionic solids is well understood, where conducting ions rapidly diffuse through the rigid lattice. The rotational motion of the lattice often facilitates the rapid ionic diffusion through the “paddle-wheel” motion. This paddle-wheel motion has since become a princi

Our long-term goal is one of designing land-based vehicles to provide enhanced uneven-terrain locomotion capabilities. In this paper, we examine and evaluate candidate articulated leg-wheel subsystem designs for use in such vehicle systems. The leg-wheel subsystem designs under consideration consist of disk wheels attached to the chassis through an articulated linkage containing multiple lower-pair joints. Our emphasis is on creating a design that permits the greatest motion flexibility between the chassis and wheel while maintaining the smallest degree-of-freedom (DOF) within the articulated

A new lateral coupling structure with independently rotating wheels (IRW) is proposed, and longitudinal creepage is obtained by replacing the gear pair with the friction pair to synchronize the rotation speed of left and right wheels. The auxiliary wheelset made up of two friction wheels can be placed either under the primary suspension or on the frame. Vehicles dynamics models with three different kinds of bogies are developed, including friction coupling bogie with independently rotating wheels (FCIRW-bogie), bogie with independently rotating wheels (IRW-bogie), and bogie with rigid wheelset
