Motorcycle Motion View Model - for Load Calculation

Sudhanshu Kashyap

Hi Everyone,

I am in the process of making a motorcycle model in motion view and wanted to get the forces on each components under several Loading cases.

I am interested in finding the forces under vertical bump condition on front and rear wheels.

But, I am facing some problems in generating the results. As, the system has been run but still no results were generated.

Can anyone help me in this. I am uploading <.mdl>file.

I have imported the frame as cad file , not .fem file.

Your frame graphic h3d is a graphic, not a flexbody.  I would recommended initially running the model without a flexbody, to get things fully debugged.  Then, create the flexbody and add it to the model.

 

So, in short, uncheck the FlexBody (CMS) feature until you get a proper flexbody created to use with the model.

Another quick observation on your model.

 

The mass and inertia values of your model are all 'zero'.  You will not get a valid solution to the basic equation F=m*a if all your 'm' are zero.

 

Kind regards,

Hi Sudhanshu - I see couple of problems with the current model.

 

1) Mass/Inertia for all the bodies are zero. You need to fix it.

2) Graphic h3d cannot be used as a flex body. You need to generate a flexbody h3d via Flexprep tool.

Thanks Praful for your reply.

How to convert flexbody h3d via flexprep tool ? As I don't have .fem file , All I have is the cad part file as a Input which I have imported as a Geometry in Motion View.

The CAD needs to be meshed to create a .fem file.  Then you can use the Flexprep tool once you have created the .fem
