Rotational displacement of a simple 2 part hinge around a coordinate system

Rotational displacement of a simple 2 part hinge around a coordinate system

Hi,

 

I am getting an error messgae when trying to apply a rotational displacement around a coordinate system on a simple 2 part hinge assembly. 

 

I have attached a word document with multiple screen shots of how i have got to the error message.

 

The hinge assembly is constraimned by a coordinate system on the barrel of the hinge and an angle offset (10 degrees) on the 2 planes through the parts. 

 

In simulate the assembly is closed, an interface connection definition applied to the mating faces.  I want to make the moving part rotate around the fixed part by adding a displacement of 3 degrees to see the impact on the asembly.  Hwoever when trying to add this ratational displacement i get the error message in the attached document.

 

Please could someone offer assistance?  What am i doing wrong and is what im trying to do even possible?

 

thanks

Hi MCR28007

 

A solid actually has no rotational degrees of freedom. You can not prescribe a rotation. Only translations

What yo u need to do is add a datumpoint, slightly removed from the citrcular endface and connect that to the endface with a  rigid connection.

Then prescribe the rotation.

Look:

Kind regards
