Stress Analysis How too Apply Loads Correctly

[Huichen_aerograce]

In this Assembly, I chose MB plate and Power Plate to conduct stress analysis. But I am quite confused how to apply loads on them? 

For MB plate:

It will be subjected to the loads caused by the gravity of other components. But the question is that, where to apply those forces? On certain points? On surfaces? And how to handle the gravatational force of top cover?

For Power Plate:

What forces will it  be subjected to? Where to apply them?

Thank you for your helppppp!!!!!!

The assembly that you attached does us no good without the associated parts.

You can assign a gravitational direction in the stress analysis.

Thanks for your prompt reply:) May I know how to do it in details? I am kind of new to inventor

To gather all the files, do a pack-n-go..
Open the assembly.
File Menu, save as. Chose pack n go.

The files will be placed in a folder. Go to that folder and zip all the files. Attach the zip file here.

When doing stress analysis you need to specify a fixed point (Which would be the point fixed to the ground), Place the gravity and then add a load.

As soon as you have send us the zip file we can have a better look at it

Heyyy! I have attach my file here:) Could you help me do a stress analysis to MB plate and power plate? I would like some illustration on how to apply the loads.
