When you say 40000 parts, is that 'just' moving parts or every single nut, bolt, rod, plate etc? When i was doing some 'blue sky' research at an architectural practice a few years ago I looked at a variety of mech eng packages for modelling skyscrapers at a level of detail which would have exceeded 40000 parts. I was interested because they were more advanced than the AECCad software available at the time and had better options for managing complexity. CATIA seemed to be the gold standard, but its very expensive and not at all intuitive. It seemed like we would need specialist technicians to operate it. Solidworks was most accessible in terms of usability. Spaceclaim was interesting but immature and didn't have much in the way of simulation. I didn't like Inventor as much as Solidworks, but that's maybe just because I tried Solidworks first. I dont know if any of these would be able to simulate the mechanical operation of the whole mechanism in one go though. I'd be very interested in hearing what you choose.
