Abstract:A disc brake is a wheel brake that slows rotation of the wheel by the friction caused by pushing brake pads against a brake disc with a set of calipers. Disk brake offer higher performance, light weight, simpler design and better resistance to water interface than drum brakes. The brake disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. This is connected to the wheel and/or the Axle. To stop the wheel, friction material in the form of brake pads, mounted on a device called a brake caliper, is forced mechanically, hydraulically, pneumatically, or electromagnetically against both sides of the disc. Friction causes the disc and attached wheel to slow or stop. Brakes convert motion to heat, and if the brakes get too hot, they become less effective, a phenomenon known as brake fade. In this project we model a disc brake using solid works design software. Then the part is imported to Ansys work bench software. Static structural and steady state thermal analysis is carried out in Ansys work bench. In static structural analysis the component is assigned with various materials at certain load. Thus the structural deformations formed due to the applied loads are studied and tabulated. In steady state thermal analysis the part is assigned with various materials and temperature loads are applied, thus the temperature distributions at applied thermal load are studied and tabulated. The material which is showing maximum performance such as low stresses and high temperature distributions in both structural and thermal wise respectively is known as the preferable material.

ABSTRACT The clutch is one of the main components in automobiles. The engine power transmitted to the system through the clutch. The failure of such a critical component during service can stall the whole application. The driven mainplate failed normally during its operation due to cyclic loading. This project explains the structural analysis of the clutch plate by changing fillet radius. This project finds the maximum stress in failure region during operation. It also suggests design modifications to improve the life time of the clutch plate.

In this paper the differential gears assembly and its housing are analyzed for the vibrational effect on a system in which the life of the gears is detrmined within different frequency range in the platform of Ansys-14.0 with use of solidworks modeling . In this type of analysis the gear housing is also effected by vibration in casing that surrounds the gear box. The main objective of gear is to protect and to provide a safe platform to get good gear transmission. It is also gives a supports for moving parts and protected it from outside condition. The differential couples and the propeller shaft on the pinion, which is runs on the ring gear or crown gear of the differential & it is also helps as the reduction in gearing friction. And enhance the life of the gear. Hence will subjected to vibration so it becomes compalsary to calculate the response of differential gear housing in different vibration conditions and it is also finding there natural frequencies. This can be most important tool in designing the differential gear housing free from fatigue failures caused by the resonance. The design of the gear housing should be appropiate a methodology for allocated with factors causing vibrations and to promote scientific means and to minimize the effects of frequencies. This vibration analysis is done by using ANSYS 14.0 software as a computational technique and validation and the modeling of differential gear box is done by using of SOLIDWORKS.

Abstract In this work thermal analysis and comparison of various duct cross sections is done computationally using Altair Hyperworks Software. Simple Analytical results were obtained for conduction and convection through the ducts which can be used to build up thermal circuit. The inner surface of all ducts is maintained at constant temperature and ambient air is at certain temperature that is less than inner surface temperature of pipe. Due to temperature difference heat will flow from higher temperature to lower temperature. Due to temperature difference heat will flow from higher temperature to lower temperature. The material of pipe provides conductive resistance and air provides convective resistance. Hence this is a mix mode of heat transfer. The heat transfer takes place in one dimension only and properties are considered to be isotropic. The ducts are assumed to be made of aluminium having known thermal conductivity and density. The surroundings of ducts have known convective heat transfer coefficient and temperature. The results are obtained on hyperview which are for heat flux, temperature gradient and grid temperature. The different characteristics can be obtained by varying the material of the ducts.

Abstract - Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. Types of honeycomb structures are depend upon the geometrical shape. There are different types of honeycomb core structures like square, hexagonal, pentagonal, tetrahedral, pyramidal etc. In this project we are comparing the structural analysis for square and hexagonal honeycomb structures and thermal analysis of square and hexagonal honeycomb structures. Structural analysis is the determination of the effects of loads on physical structure. To perform an accurate analysis an engineer must determine such information as structural loads, geometry, support conditions, and materials properties. The results of such an analysis typically include deformation, stresses and displacements. This information is then compared to criteria that indicate the conditions of failure. Thermal analysis calculates the temperature distribution and related thermal quantities in the system or component. Typical thermal quantities of interest are: The temperature distributions:(a) The time to reach steady state,(b) The steady state temperature distribution (using a transient analysis),(c) The temperature distribution after 50 seconds;The amount of heat lost or gained; Thermal gradients; Thermal fluxes.

Abstract::- This paper highlights the effect of the temperature and cutting forces generated on the tip of the Single Point Cutting Tool (SPCT) while working. In a experimental work, temperature measurement is done by using thermocouple at various depth of cut and it found that the temperature increases with increase in depth of cut. Cutting forces acting on cutting tool are determined analytically at different depth of cut. Modeling of single point cutting tool is done by PRO-Engineer Wildfire-4 software. The model is then imported in ANSYS software and meshing is done. Then the temperature readings and the forces calculated at different depths of cut are given as an input to the software. The software analyzed the model by finite element analysis at various forces and calculated the stresses developed at the tip of the tool and also the deformation of the tip of the tool. In Finite element analysis of single point cutting tool the maximum stresses are developed at the tip of tool which is the main cause of failure. Also the maximum deformation takes place at the tip of tool which blunts the tool, is the cause of failure.
