Motion study - trying to get a door to open

[barrowfordred]

Hi all,
I'm using Solidworks 2008 and I'm trying to set up a motion study that shows a door opening 60° or so from the closed position.
I've added a rotary motor and set the duration from 0s to 5s, yet when I play it back the door opens and closes in about half a second and then nothing happens for the rest of the 4.5 seconds.
I do find the getting movement out of motion study to be quite perplexing. Not at all logical.
I'd be grateful for some ideas.

Thanks.

have you tried an angle mate to position the door? If you do this you can simply change the mate angle in motion study to simulate to door opening and closing. Can you attach picture of part? Do you need instruction on angle mate procedure?

Is your assembly setup properly first off. Meaning can you manually swing the door?

In your motion study have you changed from Animation to Basic motion or motion analysis?

Where was your motor applied?

In this case its probably better to use the force and under force type select torque. This will allow you to setup a force function. You also may need positive stops on the door if you want to limit its motion or put damper on it. When applying a torque you need to be careful of your selection. If you select a face(top of door) it will apply it to the center of the face. You will want to select an edge at your hinge. If your hinge and pin have zero clearance you will want to Right Click and use the Select Other dialog in order to get the correct edge.

Thanks Matt, I cant seem to activate motion study with your part. Im able to click the tab but the motion study window does not appear. Strange, I'll keep trying.

Hows 2010 treating you?

I havent used it yet just got the cd last night.

Is there a Motion Analysis tab at the bottom?

Here is a thought for you bill. Go to Tools>add-ins and make sure you have Solidworks Motion Active.

no tab, no add in available. What suite of SW are you using? Im using professional.

I think that feature is only available in SW premium.
