1. The lateral input velocity can be changed based on unique customer test requirements, changing this parameter requires re-configuring hydraulic supply and distribution components accordingly.
2. The lateral input force can be changed based on unique customer test requirements, typical forces are between 15 and 25 kN peak force

MTS steering test systems feature an innovative, highly sensitive low-torque steering head module optimized for measuring steering effort.

• Integrates the torque sensor, motor and steering wheel angle feedback in a single, compact footprint
• Accurately replicates vehicle input stiffness and inertia, enabling realistic tests with extremely high-resolution measurement at very low torque magnitudes:
  • 113 Nm with resolution of  0.00001347 Nm,  Noise floor of +/- 0.004 Nm
  • 226 Nm with resolution of  0.00002694 Nm, Noise floor of +/- 0.008 Nm 
• Six-axis positioner that enables test engineers to match vehicle geometries exactly.
• Hand wheel can be engaged at any time during testing
• Steering inputs can be applied at the rack, I-shaft connection point or steering column input
• Also suitable for traditional durability steer tests

• Steering column reaction fixture
• Specimen fixturing
• Power steering pump drive system
