Chapter 5 Introduction to Structural Analysis of Autorickshaw 5.1 Introduction to Static Structural Analysis A static structural analysis determines the displacements, stresses, strains, and forces in structures or components caused by loads that do not induce significant inertia and damping effects. Steady loading and response conditions are assumed; that is, the loads and structure’s response are assumed to vary slowly with respect to time. A static structural load can be performed using the ANSYS. Commercially available FEA package ANSYS-Workbench is used for stress analysis. Such programs are written so that a user can solve complex engineering problems without knowing the governing equations or the mathematics. The user …show more content…
It excels in such areas as blending, hollowing and sewing. The reasons of using Parasolid form of file are Automated detail removal technology: This is required to prepare the models for downstream applications that do not require all the geometric detail typically needed for product design, manufacturing, visualization and analysis. Extended scope of interoperability: This widens the Parasolid pipeline and there by enhances value of data sharing between Parasolid based applications. Extensive range of modelling enhancements: Parasolid provides modelling automation, addition of new tapering, offsetting and detailing capabilities. Advanced surfacing, blending and chamfering. 5.4 Material Properties 5.4.1 Chemical Composition The chemical properties of the material used in present model is as shown in table 5.1 Table 5.1 Chemical properties after modification Element Content (%) Iron, Fe 97.86 - 98.33 Manganese, Mn 1.20 - 1.50 Carbon, C 0.470 - 0.550 Sulphur, S 0.0500 Phosphorous, P …show more content…
It produces the most appropriate mesh for accurate, efficient multiphysics solutions. A mesh well suited for a specific analysis can be generated with a single mouse click for all parts in a model. Full controls over the options used to generate the mesh are available for the expert user who wants to fine-tune it. The power of parallel processing is automatically used to reduce the time you have to wait for mesh generation. Creating the most appropriate mesh is the foundation of engineering simulations. ANSYS Meshing is aware of the type of solutions that will be used in the project and has the appropriate criteria to create the best suited mesh. ANSYS Meshing is automatically integrated with each solver within the ANSYS Workbench environment. For a quick analysis or for the new and infrequent user, a usable mesh can be created with one click of the mouse. ANSYS Meshing chooses the most appropriate options based on the analysis type and the geometry of the model. Especially convenient is the ability of ANSYS Meshing to automatically take advantage of the available cores in the computer to use parallel processing and thus significantly reduce the time to create a
For the other material ASTM A216 Gr WCB same pressure of 16 Mpa is applied and the stress developed is approximately as similar to the connecting rod made with material of cast iron. Figure no. 9 indicates the maximum and minimum stress developed in connecting rod at small & big end. The equivalent stress maximum and minimum values are 71.347 MPa and 4.4955e-5 MPa respectively.
Chapter four contains a series of linear and non-linear time-history analyses and includes a very thorough analytical study on the stress histories at the critical locations of the buildings. Furthermore, the contribution of each mode of vibration to total stress is investigated.
Parts, when in service and while forming, are subjected to forces. It is necessary to know the characteristics of the material to design and form the component so that any resulting deformation will not result in failure of the component in service and while forming.
In prior generations, clothing were designed by hand. Today, designers have computer-aided design. This software allows them to view designs of clothing on virtual models of a numerous shapes and sizes. In all it's the most efficient garment designing process. It saves companies both time and resources. 3-D printed apparel revolutionizes the experience of buying clothes for the average consumer.
Computer aided design (CAD) is used in design offices around the world because speed and efficiency is extremely valuable. The idea of Concurrent Design Engineering is a relatively new concept that has improved the speed that designers produce a product. Concurrent Design Engineering is a way to integrate all the processes in design back to a three-dimensional geometric data base or a CAD model. All the steps in designing a product have an opportunity to contribute to and be actively informed of decisions and changes throughout the process of design. CAD has the ability to generate fast, easy to understand models that can be altered with ease and with concurrent design engineering, any changes would be known by everybody involved. Each of the different areas of product design are equally important and some parts of the process may be able to aid another which is why concurrent design engineering is so important. Computer software and hardware is becoming so sophisticated that it may eventually eliminate the need for any analog drawing. With the improving technology the ability to transfer graphic information across the globe has become easy.
In conclusion, it is the engineers’ preference to choose one technique for calculation over the other, although there are some minor differences in the final output of the functions. The examples throughout this document highlight the benefits of Mesh Analysis against Thevenin Analysis.
...ted with CAD software to show new design details, new fabrics and colours. Design is then converted into a pattern by the system to create a prototype and pattern pieces are developed for a real sample garment. Dramatically reduces the time involved in traditional sampling. Another program which helps speed up production is CAM (Computer Aided Manufacture.)This allows Garment production now to be highly automated. Up to 500 layers of fabric can be cut accurately with advanced CAM systems. CAM systems can also print bar-coded labels and put them on the cut pieces. Optical readers scan the labels during sorting and bundling process, eliminating errors, which allows for less faults and to be delivered to retailers and consumers faster.
The objective of this lab is to illustrated the procedures required to perform tensile tests. Using data obtained from the test will enable the student to determine various material characteristics that affect the design process. Some findings/interpretations are the stress vs strain curve will help us show how the metal reacted to the forces applied, and the point of failure is very important as it is the ultimate strength.
...aints and the applied loads to the model. The rectangular composite was then basically restrained as simply supported on one side and a pressure load of 50 Mpa was applied to opposite side of the model.
The word modelling in a layman’s language is simply the process of taking a shape; 3D modeling can therefore be stated as the process of giving something shape such that it can be completed into a 3D mesh. Typically, a 3D model can be created by taking a simple object that is otherwise known as a primitive(primitives can be anything ranging from a single point object-vertex-, a two dimensional line-edge-, a curve-a spline- or a 3 dimensional object-faces or polygons-) and then one extends it into a shape such that it can be refined and detailed.

Engineering designers must consider how much metal is necessary to withstand the anticipated load for a given application. Since they can make mistakes, or the structure can be misused, they are required to over design the aircraft by a safety factor. Once the necessary mechanical load safety factor has been considered, it becomes necessary to consider whether what corrosion allowance is necessary to keep the aircraft safe.
Earthquake Engineering is a branch of Civil Engineering that is in charge of protecting the society from natural disasters like Earthquakes. This branch of Civil Engineering mainly studies how structures behave when they are hit by a seismic wave. Earthquake engineers main responsibilities are to design structures that can stand an earthquake and to make sure that all structures have the required building codes. In addition, they need to estimate the probable damages to structures after an earthquake.
