karimmec Posted August 21, 2009 Share Posted August 21, 2009 hi i want to know if cosmos works give the same results if i use weldment, screws... or only mates thanks for help Quote Link to comment Share on other sites More sharing options...
shift1313 Posted August 21, 2009 Share Posted August 21, 2009 no. welding an assembly in the real world gives different results than a bolted assembly. having said that. Cosmos Works(not xpress) i believe supports multibody parts so you should be able to analyze a weldment as it will be comprised of multi body parts. I dont have works(only xpress) so I cant tell you if it works or not. Quote Link to comment Share on other sites More sharing options...
karimmec Posted August 21, 2009 Author Share Posted August 21, 2009 thanks so should i use bolts for example or let the assembly with mates only ? Quote Link to comment Share on other sites More sharing options...
shift1313 Posted August 21, 2009 Share Posted August 21, 2009 Are you trying to analyze an assembly or are you just trying to get one component of the assembly? I dont have simulationWorks so I can only analyze individual parts so I dont know how it will work for you. What i do when i analyze single parts is use the split line feature(located on the features tab under Curves heading). This lets me "split" the face of a part with a circle that i sketch. This simulates the face of a washer. Picking your restraints and loads is something you need to know about your part and its application. Without knowing how the part is made/restrained in real life, these results will tell you nothing. Can you give me a little more insight or maybe a screen shot of what you are working with.

karimmec Posted August 24, 2009 Author Share Posted August 24, 2009 here is a picture in real its assembled by pins, should i use pins of cosmosworks here o let it with mates only tanks Quote Link to comment Share on other sites More sharing options...
shift1313 Posted August 24, 2009 Share Posted August 24, 2009 i dont have cosmos works so i dont know how you need to restrain an assembly but im going to guess the mates wont do it. I would guess when you are makin restraints you need to do as i showed above with the screen shot. You will need to select the inside of the holes. This will be a pin restraint. In your screen shot, are you point loading the edges? Quote Link to comment Share on other sites More sharing options...
