Simulation method and system for simulating drive mechanism

摘要

In place of a controlled object structure, a reaction force simulating actuator is connected to an actuator controlling the structure for recording a displacement at the connecting point. A reaction force at the connecting point after a given period of time is calculated by a digital computer on the basis of the measured value of the displacement and so forth and a known external force. The reaction force simulating actuator is actuated to realize the reaction force calculated value after the given period of time. Accordingly, since a load substantially corresponding to the reaction force from the controlled object structure is provided to a drive device, a test of the controlling drive device to be used in a condition difficult to realize can be performed under substantially similar conditions as in actual usage.
