Engine Bench System |
摘要 |
Provided is an engine bench system capable of performing a racing test with good precision. A test body is separated into an engine main body and intermediate coupling body for connecting a crankshaft and an output shaft of the dynamometer. The engine bench system is provided with: a shaft torque sensor for detecting torsional torque; a shaft torque command generation apparatus for calculating a dynamo-side shaft torque command value by summing an engine-side shaft torque command value, and a torque value proportional to the moment of inertia of the intermediate coupling body; and a shaft torque controller for generating a torque control signal on the basis of the dynamo-side shaft torque command value and the output value of the shaft torque sensor. |

1. An engine bench system comprising:
a dynamometer having an output shaft connected to a test body; a shaft torque detector that detects torsional torque at a coupling unit between the output shaft of the dynamometer and the test body, the test body being divided into an engine main body and an intermediate coupling body that connects a crankshaft of the engine main body with the output shaft of the dynamometer; a shaft torque command generation apparatus that calculates a dynamo-side torque command value corresponding to a command value for torsional torque at the shaft torque detector, by totaling an engine-side shaft torque command value corresponding to a command value for torsional torque at a coupling unit between the intermediate coupling body and the engine main body, and a torque value proportional to an inertia moment of the intermediate coupling body; and a shaft torque controller that generates a torque control signal for the dynamometer, based on the dynamo-side shaft torque command value and an output value of the shaft torque detector. |
