  • Simulating air-conditioning performance
    A computer program developed by Modine Climate Systems and Modelogics helps determine and optimize air-conditioning system performance.
  • Reduced mass haul-truck design concepts
    Liebherr Mining trucks adopted a reduced structural mass approach to convert unladen weight directly into payload, while simultaneously incorporating state-of-the-art driveline technology.
  • Optimizing a tractor frame for improved cabin NVH
    To address an aging agricultural workforce and modern ergonomic guidelines, researchers at Doshisha University and Kubota modeled medium- and large-sized agricultural tractors to reduce vibration and noise and increase comfort.
  • Applying 3d-CAD to turbocharger development
    Ishkawajima-Harima Heavy Industries has developed a 3d-CAD system for turbochargers. satisfying requirements for digital mockup development.
  • A forged steel piston for highly loaded diesel engines
    Higher peak cylinder pressures moved engineers from Mahle to search for new piston materials.
  • One world, many standards
    From Auckland to Zanzibar, the problems faced by the off-highway industry remain remarkably constant. Yet standards do not. Two industry experts discuss some of the roadblocks to global harmonization of standards.
