Eleven years ago (wow that makes me feel old), Paul Teutul Sr. and Paul Jr. took the stage at SOLIDWORKS World 2005 in Orlando. They discussed how SOLIDWORKS helped them in their custom design and fabrication of motorcycles (choppers). Unless you lived under a rock, I’m sure you have heard of their show American Chopper, or their company, Orange County Choppers.
While on stage, Paul Sr. exclaimed he had no idea what the stress plot meant, just, “Red is bad, blue is good.” This statement, while comical, isn’t completely wrong. But can be dangerous if it is not examined further.
SOLIDWORKS Simulation post processing is extremely versatile and easy to set up. The default automatic settings will show you where stress hot spots are and give you “lots of pretty pictures.” Sometimes, though, these pictures can be misleading. In the next few paragraphs, I will show you some tools in Simulation that will allow you to better understand and explain your plot results.
Explaining Simulation results to non-technical customers (or managers) can often be challenging. Depending on your color and/or deformation scale, results can look REALLY bad or not as bad as they really are. Take the images below. Both are of the same study, I just changed the scale in the legend. From a quick glance, which one seems worse?
