Dynamometer

This examples shows a dynamometer resisting a load from a prime mover. This prime mover is modeled as a torque source and could be an internal combustion engine, electric drive, or a hydraulic motor. The dyno absorbs input torque up to its limit, and allows rotation of connected loads for torques beyond. The dyno itself is modeled using the Fundamental Friction Clutch with static and dynamic limits set to the torque limit.

Simulation Results from Simscape Logging

These plots show the applied and resistive torques to the dynamometer. Note that the dyno completely absorbs torque up to its torque limit. After this, it can continue absorbing the amount up to the limit, but additional torque from the prime mover will cause the attached load to rotate.
