Analyzing SOLIDWORKS Simulation Drop Tests

Article by Lauren McGarry on Mar 23, 2022

This article is a companion piece to the latter half of this video. For more information about the options available when setting up a drop test, please see read this blog post and its associated Quick Tip video.

Animating Results

Animating a result plot is a helpful tool for sharing the results of your SOLIDWORKS Drop Test Simulation studies. To animate a result plot, right-click it and select Animate in the right-click menu.

The first time performing a SOLIDWORKS Simulation Drop Test study is typically a little slow to load as the steps are being rendered. Afterward, however, it will run smoothly.  

An animation of the Stress results shows how stresses spread through your model over time from the impact point. A color chart will appear in the lower right-hand corner of the Graphics Area, providing a key for the displayed results.

To save the animation as a .avi, stop the animation, check the box for Save as AVI file, select a location for the animation using the Browse button, then play the animation again.

Displaying Contact Forces

In the Result Force PropertyManager, we can view the internal forces that develop as a result of the model hitting the ground. To access this, right-click the Results folder and select List Interaction/Friction Force…

Select the faces in which we're interested, specify the time step at which we want to see the results, and click the Update button. 

The moment of impact is when the time is 0 microseconds. 

By changing the Plot Step, we can see how the contact forces update in the time following the impact. 

The X, Y, and Z components of the forces are listed in flyouts in the graphics area and in the Contact/Friction Force section of the Result Force PropertyManager.
