Steering Test Systems

Apply highly precise steering torque, lateral and vertical inputs to characterize, test and tune electric and hydraulic power steering systems. Available in compact 3- and 5-axis configurations, these systems are deployed worldwide by suppliers and OEMs to evaluate steering durability and characterization for passenger cars, SUVs and light trucks under real world loading conditions. 

Applications

  • Durability
  • Characterization

Test Specimens

  • Electric Power Steering Systems
  • Hydraulic Power Steering Systems

Key Product Features

Precise

A highly sensitive low-torque steering head module accurately replicates vehicle input stiffness and inertia, and features a six-axis positioner to match vehicle geometries exactly

Industry Standard

FlexTest controls and RPC software provide a highly flexible programming environment, offering function generation, time history playback and block cycle loading,

Versatile

Optional environmental chambers, vehicle bus integration solutions and a human-in-the loop interface can be integrated to accommodate evolving test requirements

Accelerated Testing

MTS Steering Systems can be integrated into hybrid simulations to extend test system utility into the early stages of vehicle design
