SimulationXpress and optimization

SolidWorks lets you design almost anything that you can imagine, but how that model is going to perform in real case scenarios is certainly unclear. Traditionally, prototypes are made and tested, but with rising technology in computers, we can test our designs without fabricating the model.




SolidWorks simulation uses same technique as simulationXpress, but the method of application is different.


SimulationXpress gives you step by step instructions on how to use this tool.


The accuracy of the results depends on fixtures, loads, and material properties. For results to be valid, the specified material properties must accurately represent the part material, and the fixtures and loads must accurately represent the part working conditions.


Using prototypes for testing is an effective method but it is expensive, so to cut costs and time, software like SolidWorks are used in industries.

We are going to perform testing on this model using simulationXpress.


Simulation can help you accomplish the following tasks:


  • Reduce cost by testing your model using the computer rather than field tests.
  • Reduce time to market by reducing the number of product development cycles.
  • Optimize your designs by simulating concepts and scenarios before making final decisions.

Now, SimulationXpress provides with many options to perform testing on any model.

Make sure that your model has no defects like surface degeneration, as these affect the results of simulation.

You can select from various options

First, let’s restrain the model from one end, let’s say that the four holes are mounting holes and thus these will come under fixed geometry.
Image 5
Select the holes and these will be fixed for the simulation process.
Click OK
Image 6
Now that we have defined the fixed part, the next step is to give the location on application of loads.
Go to ‘add a force’.
Image 7
Select the face you want to add your force to.
It is the open end of the model.

The application of stress.
The pink arrows give the uniform application of force across the face.

Next, we define the material.
Now while designing, we had already defined the material for our model.
To change the previously defined material, go to ‘change material’.
Otherwise, click next.

SolidWorks will start creating mesh and using finite element method it will solve the model for applied stress.
Image 11
After SolidWorks is finished meshing the model, it will start solving the stress problem.
Image 18
Next, animation will be shown to make the user understand the direction of application of force.
Click next to view the colored representation of stress application.

Red color represent the maximum stress acting on the part.

Weight reduction is the most important step in economical modelling.


But this can be tricky, as we don’t want to reduce the strength of our model to reduce weight, so SolidWorks performs series of simulation to try to find the perfect model which is equal in strength but has lower weight.

Image 16


After optimizing we saw that the weight is reduced and strength is slightly increased.


Strength here is maximum stress that can be applied without breaking the model.

This is the final optimized model with thickness 15mm.
