Steering Module Test Systems (SMTS)

The MB Dynamics Steering Module Test System (SMTS) is an assembly of components and software designed to facilitate the quiet testing, development, troubleshooting, and auditing of a variety of steering gear and steering column assemblies – collectively referred to as steering modules.  The system can also be used to test/audit steering system components and parts.  The SMTS test rigs are non-hydraulic, there is no high pressure oil, no risks of leaks and maintenance headaches, no negative environmental impact, and much lower equipment noise levels.  While not a durability rig, the SMTS may be used to condition or wear a steering module to varying stages of useful life within SMTS equipment limits.

MB Millenium SMTS software provides an executive function over the embedded control systems for the MB Driver Simulator (DS) and the two MB Rack Load Simulators (RLS). This executive software assures that only one embedded sub-system performs position control over the steering spline or the two tie rods.

The MB Driver Simulator product family is used to simulate driver functionality by generating repeatable and precise steering maneuvers of position/angle, angular rate, or torque using imported time histories of measured drive files or user-customizable sine, triangle, and trapezoid waveform plus CSV-imported position vs time and torque vs time.

Browse our In-Lab Driver Simulator product family

The In-Car Driver Simulator (In-Car DS) quietly produces accurate, controlled, inputs to the in-vehicle steering wheel to enable acquisition of acoustic data and wheel motions during zero-vehicle-speed and simulated parking maneuvers to characterize in-vehicle zipper and other steering noises.

Rack load simulators (RLSs) are electric, electrodynamic or pneumatic devices that apply programmable static, quasi-static and dynamic loads to one or both tie rods (synchronized with each other), delivering force vs. steering wheel/column position or force vs. time (force time histories) under closed-loop MIMO control.

As a variant on a Steering Module Test Simulator (SMTS), our Column EPS Test Bench is a quiet (acoustically and electrically), non-hydraulic, turnkey lab test system used to perform all rattle, NVH and functional tests on a column EPS just like those performed on rack-mounted EPS units.

The MB intermediate shaft test system is used to evaluate stick-slip, lash, torsional stiffness, hysteresis and other performance characteristics of I-Shafts, inner tie-rods, columns, couplings and isolators or combinations under environmental, wear and various boundary conditions.

Learn what sets our I-Shaft Test System apart

MB provides a Column Stand for mounting a steering column assembly, column EPS, and or a Driver Simulator. The steering column attaches to this Column Stand using MB-supplied, or end-user supplied, brackets at the same structural connect points where the column attaches in the vehicle.
