MTS is leveraging Hybrid Simulation to streamline and shorten test and simulation cycles and generate meaningful component and subsystem test data far earlier in development. An industry pioneer, MTS has proven two approaches for integrating physical testing and virtual models to perform objective analysis and testing, well before the availability of pre-production prototypes.
» 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; for example, using actual vehicle dampers as part of a virtual handling simulation. To date, MTS has proven its approach to mHIL applications through a series of pilot projects undertaken with major OEMs, which include four-corner damper, quarter suspension and electric power steering steer solutions. MTS engineers are currently working on mHIL systems for tires, brakes, roll bars and axles, as well as a configuration that incorporates kinematics and compliance deflection measurement (K&C) inputs. Future mHIL configurations may push the concept further by incorporating multiple subsystems (such as dampers, braking and steering) running in concert, all providing real-time data to the model.
» Hybrid System Response Convergence (HSRC) employs an offline, iterative process to generate accurate test loads by surrounding physical test parts with virtual components and generic inputs; for example, using virtual tires and digital roads as part of a full-vehicle durability test.
