mHIL
Component &
Subsystem Testing

Mechanical Hardware-in-the-Loop (mHIL) employs a real-time, closed loop process to substitute real parts for difficult-to-model components within a virtual simulation. mHIL can serve to streamline and shorten test and simulation cycles and generate meaningful component and subsystem test data far earlier in development, well before the availability of pre-production prototypes.

MTS has proven its approach to mHIL applications through a series of pilot projects undertaken with major OEMs, including:

»  mHIL Four-corner Damper System:  This solution replaces a vehicle model’s virtual dampers with four real ones in test rigs, allowing analysis at the component, subsystem and vehicle level. Capable of running literally thousands of test cases per month, this test bed enables quick detection and correction of irregular and unwanted damping system behaviors well in advance of prototype production.

»  mHIL Steer System: This solution replaces a vehicle model’s virtual steering system with a real one mounted to a 5DOF test rig with ultra-low torque measurement capabilities. This system is used to evaluate new electric power steering (EPS) system designs more quickly and easily, as well as establish better benchmarks and validation targets for suppliers of EPS subsystems. Its testing capabilities are vast, including steering rack durability and characterization, steering effort evaluation and EPS pre-tuning — all of which incorporate a real steering rack, column, I-shaft, tie rod ends, controls and wiring.
