    • 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.
