I have never seen such a beautiful video on the FEA+Vibration with Ansys solution. Good work sir. Keep it up.
Thank you !
Awsome man. Good Job.
Glad you enjoyed it, thanks.
Thanks!!! Good video!
Glad you liked it!
Thank you for information very useful
Glad it was helpful!
Dear Sir...I hve gone through ur ANSYS vdos..These r realy helpful..Thank you.
I request u to make a vdo on fatigue simution for multiaxial loading using ANSYS WB.This wil b hlpful for many CAE engineers.
Thank you for appriciation!
Sure, we will work on your requirement.
And one question, when you are saying that for damping ratio you usually consider 0.01 or 0.02, is there any reference handbook for that or it is based on your experiment? I'm looking for marsh mellow spring damping ratio. any thoughts?
You might find in manufacturing catalogue of spring. There are few uncertainty while performing analysis such as load application, FEA Model generation so based on judgment & experience we prefer to have between 1 to 2%.
I tried using this mount model in the Harmonic Analysis module (after modal for mode superposition) .When I applied an acceleration on a fixed support Boundary condition with Base excitation ON , I got an error which indicated something was unconstrained. When I remove the the spring elements and then use only 1 body the error disappears .Please help
First check modal analysis for any vibrating parts. Identify the flying body and then define connection or constraint on it.
While performing transient shock without modal analysis….we should give fix support right?
Yes!
Hello , when we model this springs for three directions , behaviour which we are getting is unrealistic…..I mean not getting realistic behaviour which will include effect of rolling and shear ….
Check the spring stiffenss values. The stiffenss values should be proper.
Dear sir,is ansys or abaqus is better for shock isolation
As vibration analysis is performed without non-linearity and hence both ANSYS and Abaqus are better. ANSYS workbench is easy for modeling and faster simulations.
Can you recommend a book for the Vibration Analysis of the Mount?
Hello, Their is no specific book for vibration mount. You will find different industry catalogs & based on size, loads & configuration, you will find different mounts.
Hi sir,
How can we define same condition in solidworks dynamaic analysis?
We have few solidwork simulation, please check the solid work playlist and try to perform the dynamic analysis.
How can we contact to clear our doubts , please share your details sir
Hello karan, you can let us know your concerns here, we will reply.
Hello sir, I have gone through your video and need help to model a device which will be helpful to me in my research.
Yes, let us know what is your concern.
Sir I am getting error, when I am using the lateral springs.. has anyone tried would need some help..
what kind of error ?
@@graspengineering9249 I think the top plate rotation needs to be constrained..then the model is able to solve else it is giving very high deformation values..
Result kaha h , where you choose rubber as a material.
This video explains how to idealize damper as spring. What results you are looking for ?
Hii Grasp Engineering, for my project in FEM simulation i need your help. I am willing to pay in returrn of help. Is there any way to contact you. Email?
