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.

In 1948, Georgia made a variable compression motor and outperformed Infiniti

At that time, when the ICE power supply systems were imperfect, and the gas distribution mechanisms were primitive, the return per liter was small, and the consumption of gasoline and oil, related to the dynamic qualities of the car, did not fit into any modern ideas, a lot of engineering minds were struggling over the riddle of increasing ICE efficiency due to changes in compression ratio. This task is not easy, and its “conveyor” solution appeared only in our time, when the relevance of the topic has come to naught. As you know, Infiniti engineers have introduced an additional link between the crankshaft crank and the connecting rod, controlling which you can change the working volume. Continue reading
