The muscles of the world. Why, after 70 years, a descendant of the Land Rover Series I got an aluminum body again? (part 2)

Computer and aluminum are power!
How to combine the strength and rigidity of the frame with the characteristics of the supporting body? It was here that engineers, along with the good old theoretical mechanics and sopromat, came to the aid of engineers many times over the past three decades, computer power. In fact, why, relying on the results of scientific achievements, with the help of computers, not choose the optimal profile of the power element depending on the expected load? Those calculations, which previously took months, today are done in … one minute. In fact, the mass of the element becomes the boundary condition: it should be as small as possible, but, say, the choice of the metal thickness and such quantities as the polar moment of inertia can be left at the computer. Combining all the characteristics, you can very quickly get your VAT options for various designs. No, VAT is not a “value added tax”, it is a “stress-strain state”, in other words, stress arising in a part when a load is applied.

Of course, this is just verbal, but at least now it can be done quickly! But do not forget that the new Defender should have been better than the old. And not only in cross-country ability, but also in traction, and in the bearing capacity of the elements. Let’s say the static load on the roof of a new SUV is absolutely unimaginable 300 kg, and the jerk load on the towbar can reach as much as 18 tons! Now it’s not the Land Rover’s driver who will run after the tractor, now it is possible and vice versa.

It is clear that in order to achieve such properties, the thickness of the metal of the supporting elements must be increased. Will there ultimately be a benefit if, abandoning the frame, make the supporting body steel, and, therefore, obviously heavy? And here the good old aluminum comes to the aid of the engineers, which is almost three times lighter than steel. The required strength has been achieved, the safety level has been ensured, the traction properties are now better than before, while the mass of the machine remains the same and does not creep up. But what about the good old steel, could it really find no place on the modern Defender? It turns out that it was found, moreover, in about the same design as before! Front Defender installed subframes – just steel. They give the lightweight aluminum body extra strength and stiffness.
And yet people in the production of SUVs are still needed!
So, after more than 70 years, the new Defender, born not without the help of modern computer technology, thanks to aluminum, became the direct heir to the 1948 Land Rover Series I. What about cross? Very soon we will test it in practice!
