I carried out my first simulation (I only have SolidWorks Simulation Standard 2020) concerning a design of a robot base. I would like to have your feedback on my study and the quality of it. I want to make sure I don't miss anything and don't make mistakes.
Some "options" of the simulation are still quite nebulous for me, if you have any clarification
- Volumetric body/beam/shell/surface: what are the differences and how to use the type of body correctly? - When studying a mechanically welded part (here designed as a single part), do you need to make connections with the weld seams? Whatever happens I haven't managed to make a weld seam, I get the message "The weld bead type connector must belong to surface body faces or sheet metal bodies". Any idea of how to solve this?
For your information, my loading case is as follows (page 73). I purposely put 2 x Fh and Mk.
I had a lot of errors when running the study (without really understanding how they were resolved, by magic in my opinion :=)):
- A sharing violation occurred while accessing [folder] - SolidWorks SIngular Matrix. Try other solvers such as Intel Solver
I am open to any criticism to better understand how SolidWorks Simulation works, or even some case studies if you have any to offer me.
To go on a Zozo_mp basis, let's say that simulation is the kind of software where paying for a 3 or 5-day training course is far from useless (especially when you see the cost of the software). On this kind of software, it's all in the modeling of the problem: hypothesis of calculations and modification of the 3D model to have something that can be calculated properly (it's quite rare to be able to calculate a SW assembly directly, a little less rare on a single part, but you often have to add surfaces, remove or add functions ...).
In terms of pure design: personally gluing 4 tubes that you can't really solder together in the middle seems absurd to me.
At the simulation level: representing welds is generally useless. You just have to consider that everything in contact is perfectly welded. (if you have places where you don't want there to be any soldering, the best is to leave a small gap of a few tenths of a mm: it will be quite close to reality)
Given the size of the foot: volume mesh without hesitation
