MB I-Shaft Test System

The MB I-Shaft test system is used to evaluate performance characteristics of I-Shafts, inner tie-rods, columns, couplings and isolators or combinations under environmental, wear and various boundary conditions.

An ultra-quiet Driver Simulator is used to apply controlled static or oscillating torsional loads. The control software acquires, computes and outputs position, wrap-up, hysteresis and other parameters of importance.
