![]() ![]() Then apply loads and restraints as normal. This will help treat the model as if it were not split. STEP 2 – Start Stress Analysis environmentįirst apply frictional constraints on all the split faces, eight in total. As there are 10 blades, we need to the split the model by a 360º angle.Īngle of Split to create single blade = 360º / No of blades It will help to change the model display to wireframe or transparent color when creating the sketch as this will allow you to see the top plate and hence aid in positioning the split-line equally between the two blades. STEP 1 – Split the model so that only one blade remains In the following example we need to determine the maximum deflection and stress in the blades when the fan is operating at 2000 revs/min. You can then apply the loads and constraints as you would for the entire model. As long as the model's loading and geometry is symmetric, we can split the part and apply frictional constraints on all resulting split faces. Typical uses include analyzing, half, quarter, or even cyclic symmetry models (as illustrated here). In addition to constraining component surfaces to freely slide along a plane they can also be used to model symmetry boundary conditions. ![]() In this tutorial I will attempt to explain how we can create efficient models giving us the flexibility to analyze results with different mesh settings and aiding us to gain some confidence in our designs.įrictionless Constraints – Define Symmetry Conditions This can lead to frustration and in some cases lead to lack of confidence in the results. ![]() ![]() This is particularly true for large or complex models which can result in a large number of elements, with the default mesh settings and with further mesh refining can significantly increase the time taken to produce the mesh. Thus, it provides greater flexibility in experimenting with different mesh sizes to help us better understand results, which would otherwise be impractical. The major advantage of this process is the reduced model sizes and reduced time required to perform analyses. Back November 29th, 2010 Inventor Simulation: Analyze with Confidenceįrictional constraints can be used to analyze a portion of a model, as briefly mentioned in my previous article on the subject, Stressed!
