In this interview, Andre talks to Richard Batchelor of CP-Carrillo about the different design considerations that go into con rods including what data they need in order to calculate your own engines inertial loads and compressive loads to supply you with a product that will give you the reliability and performance you need.
We also touch on why the old argument between I beam vs H beam connecting rods actually doesn't matter without a lot of other design information and relevant application considerations which are not actually based off your peak dyno horsepower figure but rather your cylinder pressure.

A little short, but still some useful information :-) It was a bit like pulling teeth, but Andre did bring up and get some response to one of my bugbears - rating engine (and transmission) components by 'power' when the means of producing that 'power' will load the components in quite different ways - and the chap did actually make some address to those concerns. i was a little disappointed that the material selection wasn't mentioned, but I expect there were time constraints.

@gordowg1wg145 5 жыл бұрын

@@PANTYEATR1 If you're asking, there are two primary loads on a connecting rod - inertial and compressive. The first loads the 'rod with compressive and tensile - squeezing and pulling, forces or stresses and the second is a purely compressive force. Different materials can have differing 'strengths' under each condition - for example, cast iron has excellent compressive strenght, but poor tensile strength. The other factor is the shape - under tensile loads the shape is relatively unimportant as the structure is being pulled in a line, it is really a factor of the minimum cross sectional area and the material's tensile strength - like a piece of string or wire. It is in compression and bending loads that the shape, and how resistant it is to buckling, becomes important, as I think I mentioned earlier in the comments, come to think of it?

Given the dimensional constraints of your typical V8 crankcase, which sort of force connecting rod beams into the cross-sectional dimensions we are accustomed to, an H-beam is usually slightly superior. While an I-beam's strength around its primary axis (parallel to the crankshaft) is higher than an H-beam of comparable weight, the H-beam is more "square" in its strength; i.e. it's strength around its secondary axis (perpendicular to the crankshaft) is usually identical to its primary axis number. Given that connecting rods primarily fail due to buckling, and not stretching, they will fail in the direction of their lowest strength. The H-beam's weakest axis is stronger than the I-beam's weakest axis. Why did the automotive industry almost exclusively choose the I-beam then? Because it can be forged in a single stroke. The H-beam is more complicated to forge. Simple economics masquerading as superior design.

From machining point of view it's easier to produce I beam than H beam. In 2 set-up on a HMC you can already have a conrod, and then you still have the grinding etc. But, in term of design, if you want to get the same weight with a H or I section, you will have to work harder on the weight reduction for the H beam style. Indeed, design is the answer. Marketing play also a role, and H beam from Carillo are known because of their complexity. Cylinder pressure are higher in turbo engine and H beam are less impacted by compression constraint. If you have an H beam, the section in mm² is bigger -> Comp constraint = F/S , therefore, it will be lower with H style. Higher rev in dynamic, the inertia is the main parameters, you will maybe have to consider I beam. Less inertia, less constraint but less inertia means also less material and therefore design have to help to handle the load. There is no simple answer. Engine manufacturer will test (simulation or test bench) a lot of different I or H style before releasing the final production of an high perf engine. Only the test bench can give the truth.

@@St0RM33 only true for static structures in one direction; i.e. buildings, bridges, etc. For structures of indeterminate load direction, a flag pole, etc. tubes are superior.

Essentially what he is saying is that alone, it doesn't matter if a rod it I or H beam, that is not what makes it a better rod for you given all the other deciding factors. If you're not sure, talk to your con rod supplier and give them ALL the details on your application, noting just saying you're building a 1000hp LS isn't actually much help, other engine components, boost, if the car is for circuit or drag racing etc and more should be considered. A good supplier will know all the questions to ask you though to help guide you through this as they also want to sell you the right part as well and not just make a sale on something they know will fail.

Take cast rods for example, where the choice of structure causes a negligible difference in cost, have you ever seen a cast H beam? No, what’s actually happened is that metallurgy has reached a point where a forged H beam is lighter than a cast I beam for a given stiffness.
