Abstract:

In order to study on the effects of grinding of rail head on rolling contact fatigue of rails, residual stress measurements were conducted for rails processed under different grinding conditions. In this study, residual stresses in rails used for a service line were measured with the method of X-ray stress measurement. The triaxial stress analysis was conducted using a new method for an area detector type X-ray stress analysis proposed by the authors. Four grinding conditions were used to rail specimens. The distributions of residual stresses in the surface layer of the rail head were obtained

Objective: To reduce side wear of rail elements of side track backing-up rail. Methods: Comparative and computational methods were applied in the study. Results: It was detected that in order to extend the pointwork turnout curve service life, it is necessary to reduce the side impact on an outer rail by using rail pads of diverse elasticity.

The paper tests the rail profiles of Shanghai-Nanjing PDL after its rail pre-grinding. The grinding values are counted, which shows that the grinding mainly occurs on the inner side of rail top, ranging from 0 to 1.26mm. Wheel-Rail Contact Geometry is also analyzed. Results shows that after pre-grinding, the wheel-rail contact points concentrate to the center of rail top, and it is good for rail wear control. But the rolling radius difference decreases and it weakens the rails ability of return the wheels position.

In the first pattern, the treads of both wheels are in contact with the two top surfaces of the ^-shaped guide rail; in the second pattern, the treads of both wheels are in contact with the two top surfaces of the ^-shaped guide rail, and the wheel edge is in contact with the guide rail web on one side. Based on these findings, an equivalent mechanical model with four unilateral springs is proposed to describe the wheel–rail contact.

By setting a reasonable vibration coefficient and orthogonal coefficient, the mode with the highest sensitivity to cracks is selected for crack detection. Taking a vertical crack on the rail bottom as an example, mode 1 at a frequency of 60 kHz is

Top 10 natural frequencies and mode shape characteristics of four types of light-rail box girder bridges were summarized by FE modeling. And the mode analysis results were horizontal, vertical contrasted. Furthermore, the relationships between the natural frequency and structural stiffness were studied. Finally, the bridge-types of four types of light-rail box girder bridges were optimized. The results show that the torsional stiffness of the box girder with side walls and diaphragms is much greater than that of the box girder without side walls and diaphragms, the torsional stiffness of the s

Abstract:

In urban railway environments, the problem of tramcars passing small radius arches appears to be topical. In this regard, the authors proposed that the wheelsets should be complemented on the outer side of the wheels with a second tread of a lower radius, intended exclusively for ride in arches of the track with a radius which the conventional wheelsets cannot even theoretically pass without creep. The complemented wheel tread enters into operation (or out of action) as a result of passing over a specially shaped rail located in the intersections before and behind the small radius arc. In this

Abstract:

According to the requirements of the “Rules for industrial safety of cranes”, anti-theft devices must ensure that cranes under the influence of wind force stop at any point on the track, including at the junction of rails connected by side strips. Various types of anti-theft crane devices recommended for use have a number of disadvantages. Thus, the supply of anti-theft crane devices made in the form of lever grips interacting with the rail head with mechanisms for disengaging and converging grippers with electromechanical, electromagnetic, hydraulic or pneumatic drives complicates their desig

Abstract:

Estimating the effect of rail transit on residential property values has resulted in mixed findings. Some researchers report positive effects on property values while others are negative or insignificant. The current paper argues that the impact of rail transit on property values depends on contextual factors which can influence magnitude and direction of the impact and cause variation in the findings. Tehran’s Metro Rail System is chosen because the neighbourhoods served by the metro to the north side and south side of the city are dramatically different in terms of economic, social and physi

Nowadays, vehicle lightweight design is a main topic in automotive industry. Crashworthiness, which is the most important performance of a full vehicle, must be always satisfied in the study on body lightweight design. This paper presents research, from the point of view of safety, of structural lightweight design of the front side rail of a passenger car. The response surface method is used to create mathematical models that represent the relationship between structural sheet thicknesses and absorbed energy of the entire structure in the frontal crash simulation, and the relationship between

The cracking and deformation analysis of concrete tunnel segment in the jacking process is made by ANSYS. First, we analyzed the effect of such measures as placing a hydraulic jack between the section and rail beam sliding plane described in the four sliding rails scheme upon the cracking and deformation of segment concrete, then the influence of change in spacing of two sliding rails at the same side on the cracking and deformation of segment concrete stated in the six sliding rails scheme. Meanwhile, we made a comparison between the two layout schemes, thereby providing a basis and reference

Abstract:

The wear hardness of the wheel in the gauge when passing curved sections of the track is a primary factor for traffic safety. This parameter is determined by the ratio of the transverse force that increases when the crew passes the curved section to the dynamic vertical load from the rolling stock on the rail. Using mathematical modeling in the software package «Universal mechanism», it is proved that the use of lubrication on the tracks of both track rails reduces the longitudinal forces by up to 60% in curves of small radius and up to 30% at radius up to 1000 m. It is possible to reduce the

In this paper, a numerical prediction model was established to investigate the development of rail wear on high-speed railways, and a corresponding program was written using Matlab. According to Archard’s material wear theory, the wear depth distribution in the wheel–rail contact patch and along the rail profile was calculated based on a simulation of vehicle–track dynamics and a wheel–rail rolling contact analysis. In the dynamics model, various structural components and the complex nonlinear interactions between components were precisely simulated to ensure consistency with reality. Simulati

Abstract:

The paper considers methods for analysis of size combinations of wheelsets and elements of switches that are used at determination of dimensions of gutters for check-rail assemblies. The method of limit combinations, from the one side, doesn’t guarantee a reliable train operation on crossing assemblies in real operation, but, from the other side, it makes unreasonably strict demands to the design of the assembly. In order to eliminate the contradictions the paper proposes to use a method of probable compositions that allows not only solving an issue of limited safe dimensions of gauge and gutt
