- 7. Chapter1 1.About ANSYS ANSYS is a commercial finite element code used to solve a wide variety of engineering problems in the real world. It can model many different phenomena, including heat transfer, structural response, modal analysis, transient dynamic response and fluid flow problems. ANSYS is a general purpose software, used to simulate interactions of all disciplines of physics,structural, vibration, fluid dynamics and heat transfer for engineers.So ANSYS, which enables to simulate tests or working conditions, enables to test in virtual environmentbefore manufacturing of products. 1.1Introduction to ansys software ANSYS is a product of ANSYS, Inc. The software creates simulated computer models of structures, electronics, or machine components to simulate strength, toughness, elasticity, temperature distribution, electromagnetism, fluid flow, and other attributes. Ansys is used to determine how a product will function with different specifications, without building test products or conducting crash tests. Most Ansys simulations are performed using the Ansys Workbench software, which is one of the company's main products. Typically Ansys users break down larger structures into small components that are each modeled and tested individually. A user may start by defining the dimensions of an object, and then adding weight, pressure, temperature and other physical properties.

- 9. Chapter2 2.Static structural Analysis A static structural analysis determines the displacement,stresses,strains,forces and many more in stractures or components causes by loads,moment or any valid condition.That do not induce inertia and dumping effects. 2.1 Example of static structural analysis 2.1.1Analysis of Rim: Rim is a central part of wheel over which a rubber tyre is mounted. In wheel assembly tyre mounted on the rim in between the left and right board flanges over the bead seat area. Wheel convert axle torque into the rotational motion that rotating tyre comes in contact with road surface and rotational motion gets converted into the linear motion of a vehicle, that means wheel assembly is very important part of any automobile without it vehicle cannot displaces from one position to another.

- 14. Chapter 3 3.Explicit Dynamics Analysis ANSYS explicit dynamics analysis software solutions are capable of solving short- duration, large-strain, large-deformation, fracture, complete material failure, and structural problems with complex contact interactions. Explicit time integration is more accurate and efficient for simulations involving – Shock wave propagation – Large deformations and strains – Non-linear material behaviour – Complex contact – Fragmentation – Non-linear buckling. Typical applications are drop tests and impact and penetration. ANSYS Explicit Dynamics analysis software provides simulation technology to help simulate structural performance long before manufacture.

- 21. Chapter 4 4. Fatigue analysis While many parts may work well initially, they often fail in service due to fatigue failure caused by repeated cyclic loading. Characterizing the capability of a material to survive the many cycles a component may experience during its lifetime is the aim of fatigue analysis. In a general sense, Fatigue Analysis has three main methods, Strain Life, Stress Life, and Fracture Mechanics; the first two being available within the ANSYS Fatigue Module. 4.1 Example of fatigue analysis 4.1.1 Fatigue analysis of connecting rod A connecting rod is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft.[1] The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. 4.1.2 Geometry

- 26. Chapter 5 5. Modal analysis The modal analysis calculates natural frequencies and mode shapes of the designed model. It’s the only analysis that doesn’t require any input excitation or loads, which also makes sense, as mentioned before natural frequencies are independent of the excitation loads. Natural frequency depends only on two things mass and stiffness.
- 27. 5.1 Example of MODAL analysis 5.1.1 Modal analysis of airplane An airplane or aeroplane is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. 5.1.2 Geometry 5.1.3 Material

- 31. Chapter 6 6. Stedy State Thermal Analysis In steady-state analyses, boundry conditions and loads such as temperature, convection, heat flow, radiation, heat flux etc. in thermal analyses, must not change with the changing time. If the abrupt changes in engineering analyses, the calculation much more hard. The most important material property that is needed to be defined in steady- state thermal analyses in ANSYS, is the Thermal Conductivity. You need to specify the initial temperature for the ANSYS solver. This information is required because of, if the material properties are dependent upon the changing temperature. 6.1 Example of stedy state thermal analysis 6.1.1 Stedy state thermal analysis of cylindrical fins Fins enhance heat transfer from a surface by exposing a larger surface area to convection and radiation. Finned surfaces are commonly used in practice to enhance heat transfer, and they often increase the rate of heat transfer from a surface several-fold.

- 41. Chapter 8 8. Fluent Flow ANSYS Fluent is part of the ANSYS suite of engineering analysis software, whichincludes Mechanical APDL, BladeGen, and many other software packages capable of thermalanalysis, electromagnetic analysis, and more. Fluent is also widely recognized as one of theindustry standard CFD software packages. Although Solidworks is capable of performingrudimentary CFD analysis, it is only a rudimentary approach as Solidworks is fundamentallyCAD software and is not built with simulation in mind, as ANSYS is. The versatility andcapability of ANSYS Fluent makes it an easy first choice for fluid dynamics analysis.
- 42. 8.1 Example of Fluent flow Analysis 8.1.1 Fluent Flow Analysis Natural convection flow of liquid is process of heat transfer mostly occurs due to density difference caused by temperature gradient.The process of natural convection through vertical tube has many applications like nuclear reactor, water tube boiler, solar water heating systems, HVAC applications, etc. This present work mostly useful for the design the water tube boilers and solar water heating systems. In these applications vertical copper tubes are used for the generation the steam where the flow of water takes place only due to natural convection flow.
