The CosmosWorks tutorial to analyze the response of a component to an applied load. Finite element analysis is a powerful tool that allows engineers to quickly analyze and refine a design. It can be applied to problems involving vibrations, heat transfer, fluid flow, and many other areas. In this tutorial, we will point out where choices and assumptions are made that could affect the accuracy of the results. If you check the box to the right of the add-in name, then that add-in will be activated whenever SolidWorks is started. Most users will prefer to activate COSMOSWorks only when it is needed for an analysis. Click the analysis tab. From the main menu, select COSMOSWorks: Study. A study defines a specific analysis and its results. A single part file can have multiple studies associated with it. In a static analysis, we assume that that loads are applied slowly. If loads are applied almost instantaneously, then dynamic effects need to be considered. A linear static analysis assumes that the response of the structure is linear – for example, a 20-lb load produces stresses and deflections that are exactly twice that of a 10-lb load. Boundary Conditions: When a component is isolated for analysis, the way in which that component is attached to another must be simulated with boundary conditions. In this case, we have chosen a fixed restraint, which means that every point on the back face of the bracket is prevented from moving in any direction. From the main menu, select COSMOSWorks: Load/Restraint: Pressure. Click on the face around the ½-inch hole as shown here. From the main menu, select COSMOSWorks: Mesh: Create. Move the slider bar toward the right (fine) and click the check mark. Mesh Size: A finer mesh, with more elements, will generally produce more accurate results at the expense of longer processing time.

cosmosworks introductions tutorial-design analysis made simple
Cosmosworks is a useful software for design analysis in mechanical engineering. That’s an introduction for you who would like to learn more about COSMOSWorks. COSMOSWorks is a design analysis automation application fully integrated with SolidWorks. This software uses the Finite Element Method (FEM) to simulate the working conditions of your designs and predict their behavior. FEM requires the solution of large systems of equations. Powered by fast solvers, COSMOSWorks makes it possible for designers to quickly check the integrity of their designs and search for the optimum solution. A product development cycle typically includes the following steps: 1 Build your model in the SolidWorks CAD system. 2 Prototype the design. 3 Test the prototype in the field. 4 Evaluate the results of the field tests. 5 Modify the design based on the field test results. Analysis Steps : You complete a study by performing the following steps: • Create a study defining its analysis type and options. • If needed, define parameters of your study. Parameters could be a model dimension, a material property, a force value, or any other entity that you want to investigate its impact on the design. Analysis Background: Linear Static Analysis Frequency Analysis Linearized Buckling Analysis Thermal Analysis Optimization Studies, Material property, Material Models, Linear Elastic Isotropic. Plotting Results. Describes how to generate a result plot and result tools. Listing Results. Overview of the results that can be listed. Graphing Results. Shows you how to graph results. Results of Structural Studies. Lists results available from structural studies. Results of Thermal Studies. Lists results available from thermal studies. Reports. Explains the study report utility. Stress Check. Lists the basics of checking stress results and different criteria used in the checking.

autocad-2008-tutorial-2d-fundamentals
Create and Save AutoCAD drawing files ? Use the AutoCAD visual reference commands ? Draw, using the LINE and CIRCLE
commands ? Use the ERASE command ? Define Positions using the Basic Entry methods ? Use the AutoCAD Pan Realtime option. In order to become effective in using a CAD system, we must learn to create geometric entities quickly and accurately. In learning to use a CAD system, lines and circles are the first two, and perhaps the most important two, geometric entities that one should master the skills of creating and modifying. Note that AutoCAD automatically assigns generic name, Drawing X, as new drawings are created. In our example, AutoCAD opened the graphics window using the default system units and assigned the drawing name Drawing1. Drawing Units Setup Every object we construct in a CAD system is measured in units. We should determine the value of the units within the CAD system before creating the first geometric entities. Drawing Area Setup Next, we will set up the Drawing Limits; setting the Drawing Limits controls the extents of the display of the grid. It also serves as a visual reference that marks the working area. On your own, move the graphic cursor near the upper-right comer inside the drawing area and note that the drawing area is unchanged. (The Drawing Limits command is used to set the drawing area, but the display will not be adjusted until a display command is used.). Visual reference, Using the buttons is a quick and easy way to make changes to these drawing aid options. The CAD Database and the User Coordinate System.
