Computer Aided Servohydraulic Test Rigs for Earthquake Simulations.

摘要

This report covers earthquake testing research by using automated equipment simulation models. Earthquake motions either in the ground or in a building are characterized by the low-frequency contents, typically 1-33Hz. This implies large displacements and the only way to produce such motions is using servohydraulic actuators. Earthquake testing by applying a true earthquake motion is not correct. If the equipment is mounted in a building, the dynamic behavior of the building must be accounted.
