Thanks for the great video. Can you please help me simulate a milling machine cutting tool ? I mean a tool for roughing with defining the cutting force on the end of the tool with defining RPMs? I think the more accurate question is that, can such a simulation be done using SolidWorks? Many thanks in advance
I’m doing a load path study on a slider-crank mechanism. I did a static study placing a torque on the crank and seeing what happens. However how would I determine the maximum speed and force that the crank can handle. As well as the slider?
Linear static analysis does cannot handle variable loads. If you want to simulate the stresses on a design based off a variable load, then you will need to run a Nonlinear Dynamic analysis. If you do not have access to this tool, please feel free to contact a sales representative at GoEngineer to purchase this software as well as training in how to use it.
If this was a force load, then I agree it would start by going down. But I applied a base excitation acceleration load so it is as if this device is bolted to a shaker table that is vibrating up and down in at a 30 m/s^2 acceleration. So if the whole device starts by going down, then that is why we see the response of the device going up at first.
Hi is there any way to correctly add damping values on both parameters for beta and alpha for Nonlinear dynamics?, like for example you do a bullet impact test, is there any way to determine the correct damping for this? thanks..
The Rayleigh damping parameters are used to simulate numerical damping to reduce high frequency noise during the simulation process. It cannot be derived directly from experiments but can be obtained from modal damping ratios at a few frequencies of a system. A good source for these values would be research publications that can be found on Google Scholar that are similar to the case you are trying to study.
@@goengineer Hi thanks for the response, if you can give me a link to where i can get this values to at least the correct way specially for doing fast impacts like ballistic, yes i know its not possible for tearing of mesh but at least it would be best if i can at least know or estimate the damping needed for such scenarios, thanks very much for your help..
Hello, sir, can you make the solidworks model of this spring mass damper system on your youtube channel. Use 𝑚 = 1 kg, 𝑘 = 40 N/m. Set the initial value for 𝑦, 𝑦0 = 0.1 m. Evaluate 𝑏 for the critically damped system. For the working model version, make the spring at least 0.2 m long and ensure the mass is clamped securely to it in the model. Damping ratio of b (kg/s) = 0 , 2 , 4 , 6, 8,10, 12

Where I can get your solidwork files to perform experiment by myself?

How did you determine the values you used in the Time Curve as well as the 30m/s^2?
Great video! I was wondering, you applied the acceleration excitation downwards, but why does the reaction seem to start off as upward?

Damping... Damping... Damping.... NOT DAMPENING!!! Why does everyone want to make things wet!??!
It's like nails on a chalkboard
