• Laboratory Investigation of Seat Suspension Design Performance during Vibration Testing
  11/1/2006 - Conference papers
  Researchers performed laboratory studies on four passive and two semi-active seat suspension designs. These six seat suspension systems were tested and analyzed, for vertical vibration only, using the ISO 5007 Standard.
• Field Evaluation of Seat Designs for Underground Coal Mine Shuttle Cars
  11/1/2006 - Information Circulars
  NIOSH researchers conducted a study to gather additional data to support earlier findings that NIOSH seats, with unique viscoelastic foam padding, are improved designs for coal mine shuttle cars.
• Evaluation of Seat Designs Relative to Transmitted Vehicle Vibration on Underground Mine Transport Vehicles
  10/1/2006 - Conference papers
  This study focused on reducing injury risk by improving seating on transport vehicles such as scoops, mantrips, personnel carriers, and rail-mounted locomotives.
• Musculoskeletal Symptoms Among Operators of Heavy Mobile Equipment
  6/1/2006 - Conference papers, NIOSH/USBM numbered publications
  The purpose of this study was to assess the adequacy of the cab design and to determine the percentage of musculoskeletal symptoms among operators of mobile equipment used in mining and construction.
• Pneumatic Active Suspension Design for Heavy Vehicle Seats and Operator Ride Comfort
  6/1/2006 - NIOSH/USBM numbered publications
  Handling of heavy vehicles such as tractors, trucks and buses require a large roll stiffness which causes large high accelerations at the seat level during impacts; a pneumatic active seat suspension is proposed.
• Working in Unusual or Restricted Postures
  2/1/2006 - Book chapters
  Experience has shown that many ergonomic techniques used to analyze or design standing or sitting work stations often do not adapt well to situations where a restricted posture is adopted. However, recent years have seen an increase in research examinin...
• Comparison of Seat Designs For Underground Mine Haulage Vehicles Using the Absorbed Power and ISO 2631-1(1985)-Based ACGIH Threshold Limit Methods
  7/1/2005 - Peer reviewed journal articles
  NIOSH researchers evaluated four seat designs on mine haulage vehicles with regard to roadway-induced jarring/jolting and operator comfort; the performances of the seat designs are compared.
• A Checklist for Evaluating Cab Design of Construction Equipment
  10/1/2003 - Peer reviewed journal articles
  This article introduces a one-page checklist for evaluating cab design of construction equipment.
• Systematic Comparison of Different Seats on Shuttle Cars Used in Underground Coal Mines
  8/1/2003 - Conference papers
  A field study was conducted to evaluate four seat designs on shuttle cars, including two NIOSH-designed seats.
• The Consequences of 'Leaky' Enclosures
  1/1/2002 - Peer reviewed journal articles
  Discusses design criteria for making a proper acoustical enclosure where a machine operator can safely and effectively work.
