Method and system for vibration test

摘要

A vibration testing system is economical and has high precision in realizing an equivalent test condition for testing for an entire structure, by employing a partial model by coupling testing of a partial structure and analysis of a numerical model with respect to a large structure or a structure having a portion that is difficult to establish the numerical model. In the vibration test using an actuator, a reaction of the member of the structure is detected to derive a vibration response after a given period of time at a boundary between the numerical model and the member. Excitation is performed so that the response of the actuator after the given period becomes consistent with a calculated value to make it possible to apply the response calculated with respect to the numerical model to the member by the actuator at the same timing to the actually occurring timing.
