SolidWorks SimulationXpress is design analysis software fully integrated with SolidWorks that simulates testing a part prototype under working conditions. It helps evaluate how safe, efficient, and economical a design is. The process involves building a SolidWorks model, manufacturing a prototype, testing it under loads, and modifying the design in SolidWorks until satisfied. Analysis reduces design cycles, costs by simulating tests, and time to market. It uses the finite element method to subdivide a model into simple elements and solve problems too complex for analytical solutions. Common analyses include static stress analysis to calculate displacements, strains, stresses, and reaction forces.

What is SolidWorks SimulationXpress? SolidWorks SimulationXpress is a design analysis software that is fully integrated in SolidWorks. SolidWorks SimulationXpress simulates the testing of your parts prototype in its working environment. It can help you answer questions like: how safe, efficient, and economical is your design?
The Procedure using SolidWorks SimulationXpress Use SolidWorks to build the model. Manufacture a prototype. Test the prototype under various loading conditions. Instrumentation is needed in most cases. Based on results, modify the model in SolidWorks, build a new prototype, and test it again until you are satisfied.
The Procedure using SoliWorks SimulationXpress Satisfied ? SOLIDWORKS Prototype Test Mass Production Yes No
Benefits of Analysis Design cycles are expensive and time- consuming. Analysis reduces the number of design cycles. Analysis reduces cost by testing your model using the computer instead of expensive field tests. Analysis reduces time to market. Analysis can help you optimize your designs by quickly simulating many concepts and scenarios before making a final decision.
The Finite Element Method (FEM)
The Finite Element Method Analytical solutions are only available for simple problems. They make many assumptions and fail to solve most practical problems. SolidWorks SimulationXpress uses the Finite Element Method (FEM). Analysis using the FEM is called Finite Element Analysis (FEA) or Design Analysis.
The Finite Element Method FEA is very general. It can be used to solve simple and complex problems. FEA is well-suited for computer implementation. It is universally recognized as the preferred method of analysis.
Main Concept of Design Analysis The FEM replaces a complex problem by many simple problems. It subdivides the model into many small pieces of simple shapes called elements.
Static or Stress Analysis This is the most common type of analysis. It calculates displacements, strains, stresses, and reaction forces. SimulationXpress uses von Mises stress analysis A material fails when the stress reaches the materials Yield Strength
Static or Stress Analysis
Static or Stress Analysis
Analysis Steps 1.Assign materials. What is the part made of? If there material is not listed you will have to create that material The most important property is Yield Strength 2.Specify restraints. Which faces are fixed and do not move? You must have at least one restraint
Analysis Steps 3.Apply loads. Where are the forces or pressures acting on the part? 4.Run the analysis. 5.View the results. What is the factor of safety? What are the resultant displacements or stresses?
Understanding the Analysis The Analysis is just a reference to what to expect and does not yield a absolute trust worthy value. The analysis should be used as a guide to your design and give a starting point for testing. Use factor of safety to take into account uncertainties and give your design a safe load rating. Confirm this rating by actual testing of the real part.
Understanding the Analysis Factor of Safety (FOS) is simple how over or under design a part is expressed as a number. A number Larger then 1: Over-designed and safe A number equal to 1: designed right at the breaking point A number smaller then 1: Under-designed and will break FOS = The maximum load the design can handle The load applied to the design in the analysis
How to use SimulatonXpress Suppose that we have already design a part. In this case, a Beer bottle Opener.
