Piston is considered to be one of the most important part of internal combustion engine. Piston is used to deliver thrust via connecting rod to the main shaft of the engine. Normally it is made of cast iron which bears high gas pressure and has damping property. The main objective of this chapter is to perform structural and thermal analysis of MgZrO3 top surface ceramic coated piston. Piston made up of gray cast iron coated with ceramic material (MgZrO3) which is bonded by special material (NiCrAl) is designed by machine design approach to determine the dimensions of the piston and Finite Element Analysis (FEA) was performed using ANSYS 17.1. The pressure of the 5 N/mm2 was applied at top land of piston. An equivalent Von misses stress in ceramic coated piston was found less in comparison to uncoated piston. Thermal analysis of both coated and non-coated piston was performed.

Brake Drum

The brake drum is a specialized brake that uses the concept of friction to decelerate or to stop the vehicle. The deceleration is achieved by the assistance of the friction generated by a set of brake shoes or pads. During the brake operation heat is ejected out this causes damage to the brake. Disc (Rotor) brakes are exposed to large thermal stresses during routine braking and extraordinary thermal stresses during hard braking. To satisfy this condition the drum material should possess a high thermal conductivity, thermal capacity and high strength .The common material used for construction of brake drum is cast iron. The aim of the project is to design, model a disc. Modeling is done using catia. Structural and Thermal analysis is to be done on the drum brakes using four materials Stainless Steel, gray Cast iron, carbon carbon composite & aluminum metal matrix. The shoes of this kind of brake are contained within the drum and expand outwards when the brake is applied. Such kind of brakes is used in medium heavy-duty vehicles. Structural analysis is done on the drum brake to validate the strength of the drum brake and thermal analysis is done to analyze the thermal properties. Comparison can be done for deformation; stresses, temperature etc. form the three materials to check which material is best. Catia is a 3d modeling software widely used in the design process. ANSYS is general-purpose finite element analysis (FEA) software package. Finite Element Analysis is a numerical method of deconstructing a complex system into very small pieces (of user-designated size) called elements.

The internal combustion engine should be enlarged the cylinder diameter for the Power requirements. In order to ensure the engine to work normally, it is needed to compute the strength of the connecting rod. Through adopting ANSYS software, the three-dimensional computational model is constructed, and the stress analysis is carried out. We can learn the stress field of process of deformation. Through calculation the stress and strength of connecting rod are derived. Using the stress which was calculated from ANSYS we can decide the Safety of connecting rod. In general, the analysis is meaningful to optimize the design of connecting rod.

<span>It is important to predict the temperature in some of the essential parts in machine design to prevent the machine from any damage. Most researchers usually not given much attention on thermal analysis during machine design as much as the electromagnet design. Therefore, in this study, two types of thermal modelling were proposed to predict the temperature of a permanent magnet synchronous machine (PMSM). Infolytica ThermNet software has been used since the software is related to Infolytica Magnet and the losses obtained from the electromagnetic field analysis are used as the heat source in the thermal analysis. Comparison has been done between the predicted temperature from lumped parameter model and finite element analysis. The results also will be validated by using experimental setup. Since Infolytica Magnet has been used to analyse the electromagnetic output therefore finite element analysis model is the better choice.</span>

Purpose The purpose of this paper is to realize the lightweight of connecting rod and meet the requirements of low energy consumption and vibration. Based on the structural design of the original connecting rod, the finite element analysis was conducted to reduce the weight and increase the natural frequencies, so as to reduce materials consumption and improve the energy efficiency of internal combustion engine. Design/methodology/approach The finite element analysis, structural optimization design and topology optimization of the connecting rod are applied. Efficient hybrid method is deployed: static and modal analysis; and structure re-design of the connecting rod based on topology optimization. Findings After the optimization of the connecting rod, the weight is reduced from 1.7907 to 1.4875 kg, with a reduction of 16.93%. The maximum equivalent stress of the optimized connecting rod is 183.97 MPa and that of the original structure is 217.18 MPa, with the reduction of 15.62%. The first, second and third natural frequencies of the optimized connecting rod are increased by 8.89%, 8.85% and 11.09%, respectively. Through the finite element analysis and based on the lightweight, the maximum equivalent stress is reduced and the low-order natural frequency is increased. Originality/value This paper presents an optimization method on the connecting rod structure. Based on the statics and modal analysis of the connecting rod and combined with the topology optimization, the size of the connecting rod is improved, and the static and dynamic characteristics of the optimized connecting rod are improved.

A three-dimensional coupled fluid-thermal finite element simulation model has been developed to provide analyzing distribution of velocity and temperature of nine-spacer nozzle by using FEM simulation of FLOTRAN module in ANSYS 6.0. To explore fluid-thermal analysis of the flow fields of nine-spacer nozzle of aluminum roll-casting, stricter analysis of postprocessing result was conducted by MATLAB. It was concluded that flow field of nine-spacer nozzle was able to match cooling capacity of cast rollers, but nine-spacer nozzle’s geometric flaw didn’t suit for working in the case of speed increasing of the drawing-sheet and thickness reducing of the aluminium sheet during roll casting.
