Correctly assess the required amount of force

The NASA, REFA, NIOSH module for RAMSIS Automotive enables the assessment of two-handed lifting movements which are performed repeatedly over a longer period (NASA) and the assessment of the motions involved in lifting and carrying objects (REFA). It also offers a discomfort and maximum force analysis (NIOSH).

Functional highlights

Optimal operation and maintenance

 

NIOSH analysis

  • Calculation of a recommended load limit
  • Representation of influencing sizes in factors
  • Factors provide pointers for improvements in design and work operations

 

REFA analysis

  • Calculates individual normal force, maximum force and the associated limit load
  • Addresses a multitude of various influencing variables

 

NASA Discomfort analysis

  • Joint-related, static-physical whole body evaluation
  • Influences affecting discomfort:
    • degree of utilization N (G)
    • joint point resistance W (G)
    • joint torque M (G)
    • Deviation from reference posture (NASA 0g)
    • Normal force F

 

Maximum force forecast

  • Analysis of the maximum, tolerable and sustainably achievable force
  • Taken into consideration to achieve this:
    • user-defined joint chain in actual posture
    • body dimensions, gender and age group
    • direction in which the force should be effective
