crushers torque speed curve

  • Vehicle acceleration and maximum speed modeling and ...

    The Engine model is quite simplistic. The input (current engine speed) is filtered and saturated to a minimum and maximum values.The role of the filter is to simulated the mechanical inertia of the engine. The saturation block makes sure that the engine speed doesn''t go below idle speed (1000 rpm) and does not exceed the maximum value (6500 rpm).
