Abstract:

Nut embedded disc grinding wheels, also known as disc grinding or F-Type wheels, are required for many production jobs. Nut pull-out is a common problem encountered in disc grinding wheels. The present work proposes a simple fixture, using which the integrity of the nut in the grinding wheel can be assessed. This method can be adopted by any grinding wheel manufacturer for a realistic estimate of nut pull out strength in double disc grinding wheels.

Abstract:

This paper studies on how to design a new kind of permanent magnet synchronous motor according to the need of electric wheel. We broaden the limits from the power density and moment of inertia, and focus on security, speed control range, start torque, overload capacity and so on. By linking mechanism, the motor is connected to wheels and drive them directly. The motor and the wheel hub also remain relatively independent. So the motor inherits the advantage of electric wheel and broadens the limits from dimension at the same time.

The interaction between wheel-rail produced defects on each other. Many studies of wear were done using pin-on-disc tribometer on interaction between the wheels – rail. The present paper proposes analytical study on wear. Wear rates were determined using depth of wear prediction on the interaction surfaces between wheel-rail. This prediction has been validated using pin-on-disc experimental technique using normal load of 100 N. The results show that the predictive equation developed can be used to predict the actual wear rate.

The aim of this paper is to estimate the damage of railway carriage wheels caused by lock-up braking. First, we investigate the typical characteristics of wheel-rail contact including the parameters of contact patch, longitudinal creep and coefficient of adhesion. Then we show the current requirements concerning the wheel-slide protection systems and determine the points which should be reviewed. To predict the effect of the sliding phenomenon, material properties are needed, as well. Afterwards, a simplified thermal simulation is built to estimate where martensite formation may occur.

Field statistics of the wheelsets of gauge-widened coaches in the Indian Railways show higher tendency for excessive wheel gauge widening for lower diameter wheelsets. Additionally, the axial flange deflection in gauge-widened wheelsets increases nearly linearly with the radial distance. In this work, a finite element model is developed to investigate the reasons behind these field observations. The model considers heat generation during braking, heat loss to rail, brake blocks, ambient air, residual stresses generated during wheel manufacturing, and material removal during wheel reprofiling.

A number of approximating linear empirical formulas have been obtained. They offer a powerful tool in designing and optimizing railway wheels. The most effective measure to reduce thermal and mechanical stresses

Abstract:

Ridging has been identified as a mechanized substitute for flat-land form and mounding in the cultivation of root and tuber crops. Manual ridging imposes high drudgery, consumes time and limits production scale. Therefore, mechanized ridging is necessary to improve efficiency, reduce cost and enable large-scale production. In this study, performance modelling and operational optimization of disc angle and tractor speed for a double-row disc ridger were established using CCRD in RSM. Quadratic models generated by RSM were used to predict optimum draught, wheel-slip and fuel consumption while ma

Abstract:

Agricultural fields are usually subjected to high amounts of traffic from field operations. The influence of traffic on sandy loam soil in three tillage systems were investigated in a field experiment. The field was located in a Canadian prairie region. In the experiment, the treatments were three tillage systems: no-tillage, disc tillage, and spring-tine tillage. Following tillage operations, field plots were trafficked with one pass of a sub-compact tractor. Soil properties were measured before and after the traffic to examine the effects of tillage systems and wheel traffic. For the effects

Abstract:

During aircraft braking, the change of ground adhesion forces can cause forward and backward vibration of the landing gear, and the performance of the brake disc may exacerbate this vibration. In order to solve this problem, a rigid–flexible coupling dynamic model of a two-wheel strut landing gear considering the friction characters of brake discs with different materials and a hydraulic brake system model is established in this paper. The brake disc friction characteristics effect on the low-frequency brake-induced vibration of the landing gear given different brake disc materials and ambient

Abstract:

The steering wheel of a Formula Student car has an important influence on the driving and handling stability of the car. The steering wheel of the racing car must have good mechanical and stable performance, taking into account lightweight and economic performance. Due to the small riding space of the car, the size of the steering wheel is not required to be too large. In this case, it is very difficult to meet its harsh stress state and control its vibration and noise. Based on the general requirements of the competition rules of the Formula Student racing competition, this paper constructs t

European Environmental Agency estimates that about 120 million people in the EU (over 30% of the total population) are exposed to traffic noise above 55 Ldn dB. It is estimated that 10% of the EU population is exposed to noise associated with the rail traffic. The two main sources of traffic noise comes from vehicles engines and the noise generated in the contact between the wheel and the road. In the latter the considerable part the noise is due to phenomena occurring in a wheel tram – rail system. Therefore, the problem of reducing the noise generated by railway vehicles is the subject of ma

Ferrite-pearlite steel is the most widely used material for railway wheel. However, such wheel steel can not meet the strict demands for rolling contact wear and fatigue resistance with the rising speed and weight of traffic. The aim of this paper is to improve the rolling contact wear and fatigue resistance of wheel steel by laser dispersed treatment. Such treatment creates isolated glazed regions on the surface layer of wheel steel, which are composed of fine martensite and retained autensite and have an avera0ge hardness of 762HV0.3.

Abstract:

Excessive friction at the wheel–rail contact can limit the lifespan of the wheels and rails. Meanwhile, insufficient friction can lead to increased braking distance, risking safety. Top-of-Rail (TOR) products are recognised for their potential to achieve intermediate friction levels at the wheel–rail contact and mitigate wear damages. However, the impact of these products on the airborne wear particles emitted from wheel–rail contact is not thoroughly evaluated. High particle concentration levels, particularly on underground train platforms, raise respiratory and cardiovascular health concerns

Brake judder is defined as disc or drum deformation-induced vibration which typically occurs at frequency less than 200 Hz. There are two types of brake judder namely, low speed (cold) judder and high speed (hot) judder. These two types of judder are often causing the brake pedal, steering wheel, suspension or chassis to vibrate. Consequently, it will affect comfort level of the driver and passengers. This paper focuses on the experimental investigation of low speed brake judder. In doing so, a laboratory test rig consists of disc brake unit, steering and suspension systems was used to assess

Abstract:

The grinding performance of wheel remarkably decreases by the wheel loading in dry grinding of precision hard carbon parts. When the wheel loading occurs, the dressing is carried out to remove loading chips for generation of the grinding performance. However, many abrasive grains, which have enough cutting ability under loading chips, are removed in dressing. We therefore have developed the wheel surface cleaning using adhesive films without dressing to remove loading carbon chips on wheel surfaces in our previous reports, and the cleaning could achieve the lean regeneration of grinding perfor
