Line body and Surface body how they work?

Hello Everyone,

I am using ansys 18.2 version and I am making conical spring which is line body and compressed by two surface body. When I apply force or displacement spring is passing through bottom surface plate. I have applied Bonded contacts between line body to top surface plate and another bonded contact between line body to bottom surface plate and frictionless between line body to bottom plate( surface body) . but still it is passing through each other.

What should I do?

First Bonded contact

Second contact

Frictionless contact

And shell thickness effect is also on yes in all contacts.

Best Regards,
