Nice model! Only two suggestions:
You can merge below three solids which are made of steel in to one, doing this you can avoid bonded contact between them.
You can use Static analysis - advanced solver which has more boundary condition options. Using that solver you can also apply force, pressure, remote force etc. and several other variety of loads.
Hope this helps to make your simulation more awesome. If you have any question/s, feel free to ask. Happy Simulating!.
