The disc brake is a device that used for reducing speed or discontinuing the cycle of the vehicle. many times, using the brake for vehicle starts to heat producing during braking process, such that disc brake undergoes breakage due to high temperature. Disc brake design is done through creo 4.0 and analysis is completed by using ANSYS18.1 workbench. The main purpose of this project is to study the Thermal analysis of the Materials for the Cast Iron, Stainless steel and aluminium alloy at various disc rotor profiles. A comparison between the three materials and profile for the Thermal values at maximum speed of the vehicle.

Hierarchy Process

This study is an approach to investigate the environmental impact of screw manufacturing and to choose suitable material for selected screw-making processes for the best performance with minimum environmental impact. The parameters involved were types of material and screw-making process using the environmental data available in Asia region. The two different manufacturing approaches being evaluated were machining and forging. The types of material considered were low carbon steel, stainless steel, titanium alloy and aluminium alloy. As for machining process, the materials being considered in screw manufacturing were low carbon steel, stainless steel, titanium alloy, aluminium alloy, magnesium alloy and cast iron. The information of environmental impact are generated by SolidWorks. Sustainability tool was used in the formation of pair-wise comparison matrices for Analytic Hierarchy Process (AHP). Then, the ranking of global priorities had enabled the determination of appropriate material to be used for those selected screw manufacturing process. As a result, aluminium alloy was found to give minimum environmental impact for forging process whereas cast iron was found to excel in machining process. At the same time, titanium alloy was not suggested to be used in either process.

Brakes are the most important component of any automobile. Brakes provide the ability to reduce or bring automobile to a complete stop. The process of braking is usually achieved by applying pressure to the brake discs. The main objective of this research paper is to propose an appropriate design and to perform analysis of a suitable brake rotor to enhance the performance of the high-speed car. The design of the brake disc is modelled using Solid works and the analysis is carried out using Ansys software. The analysis has been conducted by considering stainless steel and grey cast iron using same brake rotor design so that optimal choice of brake disc can be considered. The analysis considered involves static structural analysis and steady state thermal analysis considering specific parameters on brake rotor to increase the life of brake rotor. From the analysis it is found that the performance and life of disc brake depends upon heat dissipation. From the analysis results it can be concluded that grey cast iron has performed better as compared to stainless steel as this material has anti-fade properties which improves the life of the brake rotor.

High Temperature Steam

High temperature steam lines in power plant piping systems are often supported by the use of pipe support stanchions welded to the steam pipe. The end of the pipe stanchion has a steel plate welded to it, which typically slides on rack steel. The temperature of the stanchion drops from the process pipe interface along the length of the stanchion. The material for the process pipe carrying high temperature steam can be stainless steel, alloy steel, or carbon steel. The material for the stanchion can also be stainless steel, alloy steel, or carbon steel. It is of course cheaper to use carbon or low alloy steel for the stanchion as there is no steam flow in to the stanchion, when the process pipe is made of stainless steel, or other high alloy steel such A335 Gr. P91. In this paper, finite element thermal analysis is utilized first to obtain steady state temperature distribution due to decay or attenuation from the steam line surface along the stanchion. Conduction of heat from process pipe to stanchion, and convection from stanchion surface are considered. Then finite element structural analysis was performed to obtain steady state thermal stresses at the pipe-stanchion interface utilizing the temperature distribution obtained from thermal analysis as an input. The current industrial practice is to use similar materials for both process pipe and stanchion materials conservatively. Normally encountered pipe materials were considered. The materials studied include 304 & 316 Grade stainless steels, A335 Grades P91, P22, & P11 alloy steels, and A106 Grade B carbon steel. The temperature and stress results are presented. Guidelines are provided for the acceptability of pipe-stanchion dissimilar interfaces.

The paper investigates the effects of mechanical wheel slide protection devices (WSPD) on the braking capacity for coaches equipped with disc or cast iron block brakes. Decelerations and jerks, that affect the passengers comfort, are also analyzed. An original simulation program, based on experimentally determined air pressure evolutions in brake cylinder is used for this purpose. Results of numerical simulations show that in the case of repeated actuations of mechanical WSPDs, disc brake vehicles are more affected in terms of braking capacity. Regarding jerks during braking actions, in both normal and low adhesion conditions, vehicles equipped with high power cast iron block brake with two pressure levels prove to be more affected.

Abstract: Brakes are one of the most significant safety systems in an automobile. In the braking process, the rotor will be exposed to large stresses which result in surface cracking, overheating of brake fluid, seals and other components. Therefore one of the main tasks of the braking system is to reduce the surface temperature of the brake rotor. This can be achieved by choosing the right material which will undergo the least thermal stresses. In this project, thermal analysis for vented disc brake rotor of Mahindra Bolero’s done, for providing an efficient material for disc brake rotor and brake pads which can dissipate heat generated during braking at faster rate and also being structurally safe.

Mineral Kromit merupakan salah satu bahan galian yang sangat dibutuhkan dalam industri-industri stainless steel, gray cast iron, iron free high temperature alloys, dan chromium plating untuk perlindungan permukaan. Di dalam mineral industri, khromit diproses bergabung dengan magnesite seperti magnesia sintered, magnesia calcined dan binders seperti clay, lime, gypsum, bauxite, dan corundum. Hasil yang diperoleh berupa bahan yang tahan terhadap tekanan, tahan terhadap perubahan temperatur, baik sebagai isolasi antara tembok bangunan terhadap asam. Biasanya persentase yang dicari adalah FeO.Cr2O3 dengan kadar Cr2O3 > 42% dan FeO <15% .Berdasarkan hasil analisis mineralogy butir terhadap contoh konsentrat hasil dulang yang diambil selama kegiatan pemboran didaerah Topogaro, Kabupaten Bungku Barat, Sulawesi Tengah diperoleh prosentase mineral kromit (Fe2Cr2O4) dengan kandungan Cr2O3 dalam konsentrat dulang berkisar 7.961%-13.93%Dari hasil penyelidikan permukaan, pemboran dan analisis laboratorium diketahui secara umum mineral kromit dapat dipisahkan dari mineral pengotor sehingga meningkatkan kadar kromit.
