Thank you very much for this great presentation. I have one question: in Static analysis you used distributed mass and gravity, but in linear dynamics there was distributed mass and force. Why force is equal to 260 lbs?
@goengineer2 жыл бұрын
The direct answer to your question is that the force is the weight of the person that I'm simulating in this case. I can't remember why I chose this weight in particular. Something like the weight of some of the taller NBA players, but it more than likely came down to some interesting behavior I wanted to show in the results that happened around this value. A bit of a "for presentation purposes only" Goldilocks number. Some additional discussion: There is a difference between WEIGHT and MASS that I will assume is already understood by the reader. The inclusion of MASS is for the getting accurate frequency responses which depends both stiffness and mass. We used 260 lbm because the analysis of the person hanging from the rim is including the mass of the person (260 lbm person assumed here). However, the inclusion of mass alone will not create deformation in a dynamic study (and therefore stresses and strains) unless I include gravity. So either I can enable and disable gravity to control the loading conditions, or I can turn on and off forces. I decided to do the latter in this case as it's a bit more direct and gives me more control.

Nice video! At 21:58, why did you apply both mass and force? Since you added force, shouldn't you delete the mass?
@goengineer Жыл бұрын
Thank you for your question. Without the MASS the basketball hoop resonates very quickly (as if there is no person hanging onto it). Without the FORCE, there is no downward displacement. So I need both. Note: another way you might consider doing this might be to apply MASS and GRAVITY, but notice that GRAVITY is not available as a load in this study as I mention at 21:40.

Hey. great work. but just a request. can you provide me with the solidworks model ? so that I can try to perform the same analysis myself. thanks.

The model used here is available in the SOLIDWORKS Simulation tutorials so you already have it on your machine if you have SOLIDWORKS installed. You may go to Help | SOLIDWORKS Simulation | Tutorials | SOLIDWORKS Simulation Premium | Time History Analysis of a Basketball Hoop.

Much appreciated video. I am curious to know how you were able to let go of the rim for the linear dynamic simulation as this was not shown. I know you mentioned running a separate study, would I essentially let my mass y_val in the time curve be zero at x = 2 for example?
@willcawthra54542 жыл бұрын
also, is there a way to extract the actual time series data from the probed plots? Im trying to validate an experiment where I used an accelerometer. I'm assuming there's no way Solidworks will be able to probe for velocity and acceleration in this kind of example without taking the double derivative of displacement data?
@goengineer2 жыл бұрын
There actually may be a couple of methods for this, but the method I likely used in this presentation was to assign zero mass (since this is for the release case) and apply the load as a force somewhat slowly to load it and then release it. Then for the force curve, I likely applied a force equal to the weight (I believe I used 280lbs) and then released it probably in 1-10 milliseconds. So the curve could have had the following sample data points: (0.000s, 280.0 lbf) (0.100s, 280.0 lbf) (0.101s, 0.000 lbf) (1.000s, 0.000 lbf) More precisely I probably would have used a cosine (copied from excel datapoints) to load it more gradually to avoid excitation for the release case.

@@willcawthra5454 Yes, when you use the probe tool, select points and select Response (it looks like a graph with a little clock on it). This gives you the time history of whatever your plot is currently displaying (Displacement, Velocity, Acceleration, etc.). Typically with these type of simulations, we solve for accelerations and integrate to determine velocity and displacement. Integration parameters for Newmark or Wilson-Theta can be adjusted in the Study Properties under the Advanced Options.
