How to set up a "stiffness to weight" goal in a design study?

Chris Pellegrino Nov 24, 2015 1:45 PM

Is there a way to set up an equation goal to maximize stiffness to weight? I can't find a way to set up a global variable because that is defined in the part and does not have access to the simulation data. This is such a fundamental need for structural analysis that I find it hard to believe it isn't possible. I can't, however, find anything about how to do it in Help, or online searches.

Basics of Design Studies - SolidWorks - YouTube

If the stiffness is high, the displacement is low

Add a displacement and weight sensor to measure the values

  Um, yes, that's a given. However, I want to be able to create some custom goals that combine these for me so the Design Study can do the optimization. It's not trivial (lower displacement/weight defined too simply will always end up in the heaviest part), however setting up the correct boundary conditions should be able to achieve what I want.
