The mechanical Hardware-in-the-Loop (mHIL) Damper solution combines a computational full-vehicle model with a physical damper test system(s) and damper specimen(s) to create a vehicle-level simulation environment that enables vehicle development engineers to benchmark, characterize, set-up, tune and validate damper systems at the sub-system and vehicle levels.
mHIL techniques compress vehicle development schedules by enabling meaningful evaluation and validation subsystems and vehicles earlier in development - well before the availability of vehicle prototypes
Reduces the number of vehicle prototypes required, minimizes instrumentation and data acquisition costs and streamlines final proving ground validation
Real components can be substituted for difficult-to-model components when performing virtual simulations, enhancing characterization and improving model development
Expected and unexpected fault conditions more easily detected and safely evaluated in a laboratory environment
A Mechanical Hardware in the Loop (mHIL) system provides a laboratory method of evaluating the effects of physical chassis elements (in this case the damper sub-system) on vehicle-level attributes (in this case vehicle handling).
The damper test system applies loads and/or displacements to the mechanical damper hardware based on inputs from the vehicle simulation model, measures the hardware response, and then sends these responses back to the vehicle simulation mode. The mechanical hardware is included “in the loop” with the simulated vehicle.
The advantages of using the MTS mHIL Hybrid Simulation technique in the vehicle development process include:
