Could you explain your definition of Torque and Power in greater detail please?
I thought Torque was a force multiplied by a distance hence its units being 'Nm', therefore implying that for a given force an increase in the length away from centre of rotation will increase torque.In...
If the piston is at TDC and the crank angle still has 10deg to go then you have actually made it worse as the conrod is now making more of an angle to the cylinder axis thus increasing friction. The new Toyota Aygo/Citroen/Peugeot 107 has an offset crank, the idea is to minimize friction by...
Hi Twillcox,
Yes those look like pretty reasonable plots.
I don't have any main bearing force plots as for my work it was not necessary, all I needed was the maximum and minimum stresses for Goodman diagrams.
For vibration purposes the sum of the bearing forces will equal zero anyway as will...
Hello twillcox,
From what I can understand, you are looking for the total force through a main bearing of the crankshaft for every degree crank angle. I didn't actually do this but I can show you what the force on the conrod should look like so at least you can see if thats correct. Hopefully...
Hello twillcox,
I did quite a bit of work on this subject at the start of the year. When I was doing the work I analyzed a Ford I-4 1,6l gasoline crankshaft(its a single counterbalance per bore type) and found that Ford don't actually take into account for the mass of the big-end part of the...
