Mechanical Engineering Advances, Vol.2, No.1, 2024; 173 Views, 136 PDF Downloads

This paper defines vehicles and buildings as main sources of United Kingdom (UK) carbon dioxide (CO 2 ) and seeks to cut such emissions using green hydrogen made from combined wind and solar energy. Combustion vehicles powered by fossil petroleum emit near half of UK climate-warming CO 2 while buildings heated by natural gas provide a third. First, current UK grid problems are defined: Electricity, gas and petroleum grids. Refueling green vehicles has been a particular problem. Then experiments on the private wire community of Keele University show how green hydrogen could integrate both green vehicles and buildings. Next, the model supply chain is planned and tested. Finally, experiments and calculations are outlined, analyzing the optimum system design criteria proposed. We conclude that economic green hydrogen can displace petroleum in vehicles, while powering buildings instead of natural gas. Also, the prospect in 2024 is that profits can be made all along the green hydrogen supply chain, such that new businesses involved in local private clean communities can cost less than the National Grid monopoly and other dominant fossil energy companies.

The main distinguishing characteristic of active vibration control

by Zine Ghemari, Salah Belkhiri

Mechanical Engineering Advances, Vol.2, No.1, 2024; 82 Views, 52 PDF Downloads

Active Vibration Control (AVC) stands out as a prominent technique in the realm of vibration mitigation and structural dynamics. Unlike passive vibration control methods that rely on dampers or isolators, AVC systems actively manipulate forces or motions within a structure in real-time to counteract undesirable vibrations. In this paper, the main distinguishing characteristic of AVC lies in its proactive approach, wherein control algorithms and actuators are employed to actively sense and respond to dynamic changes in the system. The application of Newton’s second law allows to model of the vibration sensors operation, followed by simulations to improve their performance, contributes to the advancement of the active vibration control system by enabling more precise detection and measurement of vibrations.

Mechanical Engineering Advances, Vol.2, No.1, 2023; 66 Views, 37 PDF Downloads

In the paper, the MATLAB-Simulink model of simulation of operation of the fast light innovative regional train from “Serbian Railways” in traction and braking mode is exposed where changes are observed: stator currents of three-phase traction motors, traction electric motor speeds and electric multiple unit, electromagnetic torque on the rotor shaft of the traction electric motor and diirect current bus voltage. The model allowed review of the listed parameters for: different allowed values of contact network voltage and total voltage distortion at the place of connection of the electric multiple unit to the contact network, different mechanical loads of electric multiple unit and traction electric motor and different train speeds and rotation of traction electric motors. Appropriate conclusions were made through the analysis of the simulation results obtained.

Evaluating automobile’s vibration in frequency domain

by Yujie Jia, Vanliem Nguyen

Mechanical Engineering Advances, Vol.2, No.1, 2023; 29 Views, 16 PDF Downloads

To excitation of the low frequency not only influences the driver’s health but also strongly affects the durability of the automobile’s structures. To research the automobile’s vibration in the low frequency region, a dynamic model of the automobile is established to calculate the vibration equations of the automobile in the time region. Based on the theory of the Laplace transfer function, the automobile’s vibration equations in the time region are transformed and converted to the automobile’s vibration equations in the frequency region. Then, the effect of the automobile’s design parameters and operation parameters on the characteristic of the automobile’s acceleration-frequency is simulated and analyzed to evaluate the automobile’s comfort as well as the durability of the automobile’s structures in the frequency region. The research results show that the design parameters of the stiffness, mass, and road wavelength remarkably affect the characteristic of the automobile’s acceleration-frequency. To reduce the resonant amplitude of the acceleration-frequency in the vertical and pitching direction of the automobile, the stiffness parameters of the automobiles and tires should be reduced while the mass of the automobile’s body should be increased. Additionally, the road’s roughness also needs to be decreased or the road’s quality needs to be enhanced to reduce the resonant amplitude of the automobile’s acceleration-frequency.

Mechanical Engineering Advances, Vol.2, No.1, 2023; 28 Views, 9 PDF Downloads

Magnetic filters are used on companies for mass flux and volume flux values that helps to cover day-to-day production. This work begins describing the problem of magnetic filters fractures as industrial interest. A brief description of how magnetic filters must work on application, according to requirements on process line. On next sections is possible to find the explaining of structural fracture and mistakes on the design or data sheet usually not considered on guaranteed policy. Are mentioned more than one math modeling, taking the simplest to show the effective value of maximum pressure tolerated on magnetic filters differs from estimated for controlled conditions. Solutions shown on the article are a first approach of a future general model theory that could explain how applied science works on a factory where there is no time to stop production. This work relates math model and some values on application, meaning both the project hypothesis modeling on factories requirements for their equipment. Results depict volume, velocity, density, and pipeline relation to the pressure increase over the values on data sheet from quality department tests. Conclusions describe the connection of the math model analysis and with real situations on the application or possible structural damage. And its relationship with the proper function of magnetic filters for the purpose of lifespan analysis on future works. This work is a proof that on few weeks, companies can have a solution for their problems letting them to buy some time to avoid any future issue.

A review on Co3O4 nanostructures as the electrodes of supercapacitors

by Samatha Kelathaya, Raghavendra Sagar

Mechanical Engineering Advances, Vol.2, No.1, 2023; 169 Views, 139 PDF Downloads

Usage of supercapacitors in energy storage applications has now become a new trend due to its high auspicious features. Introduction of pseudocapacitance has increased its weightage to be used in greater number of practical utilization. Electrodes are the major constituents of a supercapacitor based on which the electrochemical performance of the supercapacitor is decided. Among varieties of electrode materials available, transition metal oxides are the most suitable ones to fulfill the required its criteria. Due to the occurrence of faradic redox reactions on the surface of electrodes, selection of efficient and favorable electrode material plays major role. Co 3 O 4 (Cobalt (III) oxide) is one among the most desiring electrode materials due to its various peculiar features. This paper reviews briefly on several factors of Co 3 O 4 as electrode material in supercapacitor applications. It includes comparative discussions towards different synthesize methodologies, influence of its dimensional morphology on the electrochemical outputs like specific capacitance, energy density and the power density.
