Abstract
Content
  • Changing demands reshape hydraulic components
    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 system.
  • 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.
