Changing demands reshape hydraulic
In a world of shrinking margins, fierce competition, and increasing
regulations, equipment owners want nothing less than stellar
performance from their equipment.
Contact stress in valvetrains
Engineers from Mahle compared FEA and Hertzian equations for the
calculation of contact stress in a roller-follower valvetrain
High-fidelity agricultural tires
Researchers from Goodyear and John Deere developed finite element
tire models capable of generating quasi-static spindle forces and
moments for prescribed displacements over irregular terrain.
Ag-equipment development challenges
An engineer in the field discusses the need to tread carefully
during the agricultural product-development process.
