Need help with stress analysis

[Anonymous]

Hello,

I'm trying to do an FEA on scissor lift. In the analysis they say there is a separation but it gives an answer anyway. There is a load of 1000 lbs on the lift. The picture show the scissor mechanism isolate. In fact, the answer I get for the Platform is like 3 ksi in the middle wich I believe is right. But when I come to my scissor mechanism. It looks like there is issues. On the picture we see my constraint and a few Von Mises answer along the mechanism. I find them really small. I'm wondering if the problem with the separation could be between the platform

and the mechanism. This would go along with the fact the platform numbers look fine and not the mechanisme one.

Hope my english isnt to bad.

Thank you
